+
+<p>1.2. Сервис предоставляет Пользователям следующие возможности:</p>
+<ul>
+<li>Создание и участие в игровых марафонах</li>
+<li>Получение случайных игровых заданий различной сложности</li>
+<li>Отслеживание прогресса и статистики участников</li>
+<li>Участие в специальных игровых событиях</li>
+<li>Получение уведомлений через интеграцию с Telegram</li>
+</ul>
+
+<p>1.3. Сервис предоставляется на условиях «как есть» (as is). Администрация не гарантирует, что Сервис будет соответствовать ожиданиям Пользователя или работать бесперебойно.</p>
+
+<hr class="my-8 border-dark-600" />
+
+<h2>2. Регистрация и учётная запись</h2>
+
+<p>2.1. Для доступа к функционалу Сервиса необходима регистрация учётной записи. При регистрации Пользователь обязуется предоставить достоверные данные.</p>

+<li>Все действия, совершённые с использованием его учётной записи</li>
+<li>Своевременное уведомление Администрации о несанкционированном доступе к аккаунту</li>
+</ul>
+
+<p>2.3. Каждый Пользователь имеет право на одну учётную запись. Создание дополнительных аккаунтов (мультиаккаунтинг) запрещено и влечёт блокировку всех связанных учётных записей.</p>
+
+<p>2.4. Пользователь вправе в любой момент удалить свою учётную запись, обратившись к Администрации. При удалении аккаунта все связанные данные будут безвозвратно удалены.</p>

+
+## Кто может оспаривать
+
+| Условие | Можно оспорить? |
+|---------|-----------------|
+| Своё задание | ❌ Нельзя |
+| Чужое задание (статус COMPLETED) | ✅ Можно (в течение 24 часов) |
+| Чужое задание (статус ACTIVE/DROPPED) | ❌ Нельзя |
+| Прошло более 24 часов с момента выполнения | ❌ Нельзя |
+| Уже есть активный диспут на это задание | ❌ Нельзя |
+
+## Типы оспариваемых заданий
+
+### 1. Обычные челленджи
+
+Можно оспорить выполнение любого челленджа. При признании пруфа невалидным:
+- Задание переходит в статус `RETURNED`
+- Очки снимаются с участника
+- Участник должен переделать задание
+
+### 2. Прохождения игр (Playthrough)
+
+Основное задание прохождения можно оспорить. При признании невалидным:
+- Основное задание переходит в статус `RETURNED`
+- Очки снимаются
+- **Все бонусные челленджи сбрасываются** в статус `PENDING`
+
+### 3. Бонусные челленджи
+
+Каждый бонусный челлендж можно оспорить **отдельно**. При признании невалидным:
+- Только этот бонусный челлендж сбрасывается в `PENDING`
+- Участник может переделать его
+- Основное задание и другие бонусы не затрагиваются
+
+**Важно:** Очки за бонусные челленджи начисляются только при завершении основного задания. Поэтому при оспаривании бонуса очки не снимаются — просто сбрасывается статус.
+
+## Процесс голосования
+
+### Создание диспута
+
+1. Участник нажимает "Оспорить" на странице деталей задания
+2. Вводит причину оспаривания (минимум 10 символов)
+3. Создаётся диспут со статусом `OPEN`
+4. Владельцу задания отправляется уведомление в Telegram
+
+### Голосование
+
+- **Любой участник марафона** может голосовать
+- Два варианта: "Валидно" (пруф OK) или "Невалидно" (пруф не OK)
+- Можно **изменить** свой голос до завершения голосования
+- Голосование длится **24 часа** с момента создания диспута
+
+### Комментарии
+
+- Участники могут оставлять комментарии для обсуждения
+- Комментарии помогают другим участникам принять решение
+- Комментарии доступны только пока диспут открыт
+
+## Разрешение диспута
+
+### Автоматическое (по таймеру)
+
+Через 24 часа диспут автоматически разрешается:
+- Система подсчитывает голоса
+- При равенстве голосов — **в пользу обвиняемого** (пруф валиден)
+- Результат: `RESOLVED_VALID` или `RESOLVED_INVALID`
+
+**Технически:** Фоновый планировщик (`DisputeScheduler`) проверяет истёкшие диспуты каждые 5 минут.
+
+### Результаты
+
+| Результат | Условие | Последствия |
+|-----------|---------|-------------|
+| `RESOLVED_VALID` | Голосов "валидно" ≥ голосов "невалидно" | Задание остаётся выполненным |
+| `RESOLVED_INVALID` | Голосов "невалидно" > голосов "валидно" | Задание возвращается |
+
+### Что происходит при INVALID
+
+**Для обычного задания:**
+1. Статус → `RETURNED`
+2. Очки (`points_earned`) вычитаются из общего счёта участника
+3. Пруфы сохраняются для истории
+
+**Для прохождения:**
+1. Основное задание → `RETURNED`
+2. Очки вычитаются
+3. Все бонусные челленджи сбрасываются:
+   - Статус → `PENDING`
+   - Пруфы удаляются
+   - Очки обнуляются
+
+**Для бонусного челленджа:**
+1. Только этот бонус → `PENDING`
+2. Пруфы удаляются
+3. Можно переделать

+| Событие | Получатель | Сообщение |
+|---------|------------|-----------|
+| Создание диспута | Владелец задания | "Ваше задание X оспорено в марафоне Y" |
+| Результат: валидно | Владелец задания | "Диспут по заданию X решён в вашу пользу" |
+| Результат: невалидно | Владелец задания | "Диспут по заданию X решён не в вашу пользу, задание возвращено" |
+
+## Конфигурация
+
+```python
+# backend/app/api/v1/assignments.py
+DISPUTE_WINDOW_HOURS = 24  # Окно для создания диспута
+
+# backend/app/services/dispute_scheduler.py
+CHECK_INTERVAL_SECONDS = 300  # Проверка каждые 5 минут
+DISPUTE_WINDOW_HOURS = 24     # Время голосования
+```
+
+## Пример сценария
+
+### Сценарий 1: Успешное оспаривание
+
+1. **Иван** выполняет челлендж "Пройти уровень без смертей"
+2. **Иван** прикладывает скриншот финального экрана
+3. **Петр** открывает детали задания и видит, что на скриншоте есть смерти
+4. **Петр** нажимает "Оспорить" и пишет: "На скриншоте видно 3 смерти"
+5. Участники марафона голосуют: 5 за "невалидно", 2 за "валидно"
+6. Через 24 часа диспут закрывается как `RESOLVED_INVALID`
+7. Задание Ивана возвращается, очки снимаются
+8. Иван получает уведомление и должен переделать задание
+
+### Сценарий 2: Оспаривание бонуса
+
+1. **Анна** проходит игру и выполняет бонусный челлендж
+2. **Сергей** замечает проблему с пруфом бонуса
+3. **Сергей** оспаривает только бонусный челлендж
+4. Голосование: 4 за "невалидно", 1 за "валидно"
+5. Результат: бонус сбрасывается в `PENDING`
+6. Основное задание Анны **не затронуто**
+7. Анна может переделать бонус (пока основное задание активно)
+
+## Ручное разрешение диспутов
+
+Администраторы системы и организаторы марафонов могут вручную разрешать диспуты, не дожидаясь окончания 24-часового окна голосования.
+
+### Кто может разрешать
+
+| Роль | Доступ |
+|------|--------|
+| **Системный админ** | Все диспуты во всех марафонах (`/admin/disputes`) |
+| **Организатор марафона** | Только диспуты в своём марафоне (секция "Оспаривания" на странице марафона) |
+
+### Интерфейс для системных админов
+
+**Путь:** `/admin/disputes`
+
+- Отдельная страница в админ-панели
+- Фильтры: "Открытые" / "Все"
+- Показывает диспуты из всех марафонов
+- Информация: марафон, задание, участник, кто оспорил, причина
+- Счётчик голосов и время до истечения
+- Кнопки "Валидно" / "Невалидно" для мгновенного решения
+
+### Интерфейс для организаторов
+
+**Путь:** На странице марафона (`/marathons/{id}`) → секция "Оспаривания"
+
+- Доступна только организаторам активного марафона
+- Показывает только диспуты текущего марафона
+- Компактный вид с возможностью раскрытия
+- Ссылка на страницу задания для детального просмотра
+
+### API для ручного разрешения
+
+**Системные админы:**
+```
+GET  /api/v1/admin/disputes?status_filter=open|all
+POST /api/v1/admin/disputes/{dispute_id}/resolve
+
+Body: { "is_valid": true|false }
+```
+
+**Организаторы марафона:**
+```
+GET  /api/v1/marathons/{marathon_id}/disputes?status_filter=open|all
+POST /api/v1/marathons/{marathon_id}/disputes/{dispute_id}/resolve
+
+Body: { "is_valid": true|false }
+```
+
+### Что происходит при ручном разрешении
+
+Логика идентична автоматическому разрешению:
+
+**При `is_valid: true`:**
+- Диспут закрывается как `RESOLVED_VALID`
+- Задание остаётся выполненным
+- Участник получает уведомление
+
+**При `is_valid: false`:**
+- Диспут закрывается как `RESOLVED_INVALID`
+- Задание возвращается, очки снимаются
+- Участник получает уведомление
+
+### Важно: логика снятия очков за бонусы
+
+При отклонении бонусного диспута система проверяет статус основного прохождения:

+
+**Почему так?** Очки за бонусные челленджи начисляются только в момент завершения основного прохождения (чтобы нельзя было получить очки за бонусы и потом дропнуть основное задание).

+## Логирование действий
+
+Ручное разрешение диспутов логируется в системе:
+
+| Действие | Тип лога |
+|----------|----------|
+| Админ подтвердил пруф | `DISPUTE_RESOLVE_VALID` |
+| Админ отклонил пруф | `DISPUTE_RESOLVE_INVALID` |
+
+Логи доступны в `/admin/logs` для аудита действий администраторов.

+# Система типов игр
+
+## Обзор
+
+В системе существует два типа игр, определяющих логику выдачи заданий:
+
+| Тип | Значение | Описание |
+|-----|----------|----------|
+| **Челленджи** | `challenges` | При спине выдаётся один случайный челлендж из списка |
+| **Прохождение** | `playthrough` | Нужно пройти игру целиком, челленджи становятся бонусными |
+
+---
+
+## Модели данных
+
+### Game
+
+```
+game_type: str              # "challenges" | "playthrough"
+playthrough_points: int?    # Очки за прохождение (только для playthrough)
+playthrough_description: str?   # Описание задания
+playthrough_proof_type: str?    # Тип пруфа: screenshot/video/steam
+playthrough_proof_hint: str?    # Подсказка для пруфа
+```
+
+### Assignment
+
+```
+challenge_id: int?      # ID челленджа (для challenges)
+game_id: int?           # ID игры (для playthrough)
+is_playthrough: bool    # True если это прохождение
+```
+
+### BonusAssignment
+
+```
+main_assignment_id: int     # Ссылка на основное задание (playthrough)
+challenge_id: int           # ID бонусного челленджа
+status: str                 # "pending" | "completed"
+proof_path: str?            # Путь к файлу пруфа
+proof_url: str?             # URL пруфа
+proof_comment: str?         # Комментарий со ссылкой
+points_earned: int          # Заработанные очки
+```
+
+---
+
+## Логика спина
+
+### Тип "Челленджи" (challenges)
+
+```
+1. Выбрать случайную игру из доступных
+2. Отфильтровать уже выполненные челленджи этой игры
+3. Выбрать случайный невыполненный челлендж
+4. Создать Assignment с challenge_id
+```
+
+**Игра исключается из спина**, если все её челленджи выполнены.
+
+### Тип "Прохождение" (playthrough)
+
+```
+1. Выбрать случайную игру из доступных
+2. Создать Assignment с game_id и is_playthrough=True
+3. Создать BonusAssignment для каждого челленджа игры
+4. События (Jackpot, Golden Hour и т.д.) ИГНОРИРУЮТСЯ
+```
+
+**Игра исключается из спина**, если есть Assignment со статусом COMPLETED или DROPPED.
+
+---
+
+## Завершение заданий
+
+### Челлендж (challenges)
+
+```
+POST /marathons/{id}/complete-assignment
+```
+
+1. Загрузить пруф (файл или комментарий)
+2. Начисляются очки челленджа × модификатор события
+3. Увеличивается серия участника
+4. Статус → COMPLETED
+
+### Прохождение (playthrough)
+
+```
+POST /marathons/{id}/complete-assignment
+```
+
+1. Загрузить пруф прохождения
+2. Начисляются очки за прохождение (`playthrough_points`)
+3. Бонусные очки добавляются из completed BonusAssignments
+4. Увеличивается серия участника
+5. Все pending BonusAssignments удаляются (больше нельзя выполнить)
+6. Статус → COMPLETED
+
+### Бонусный челлендж
+
+```
+POST /marathons/{id}/assignments/{assignment_id}/bonus/{challenge_id}/complete
+```
+
+1. Доступно только пока основное задание ACTIVE
+2. Загрузить пруф бонусного челленджа
+3. BonusAssignment.status → COMPLETED
+4. Очки накапливаются в BonusAssignment.points_earned
+5. **Очки НЕ добавляются сразу** — добавятся при завершении основного задания
+
+**Исключение:** Если main assignment уже COMPLETED (перепрохождение после диспута), очки добавляются сразу.
+
+---
+
+## Фильтрация игр для спина
+
+### Функция `get_available_games_for_participant`
+
+```python
+for game in approved_games:
+    if game.game_type == "playthrough":
+        # Исключить если есть COMPLETED или DROPPED assignment
+        if has_finished_playthrough(participant, game):
+            continue
+    else:  # challenges
+        # Исключить если ВСЕ челленджи выполнены
+        if all_challenges_completed(participant, game):
+            continue
+
+    available.append(game)
+```
+
+---
+
+## Система очков
+
+### Челлендж
+
+```
+base_points = challenge.points
+modifier = event_modifier (если есть активное событие)
+total = base_points × modifier
+```
+
+### Прохождение
+
+```
+base_points = game.playthrough_points
+bonus_points = sum(bonus.points_earned for bonus in completed_bonuses)
+total = base_points + bonus_points
+```
+
+**События НЕ влияют на очки за прохождение.**
+
+---
+
+## Дроп задания
+
+### Челлендж
+
+- Штраф в очках (зависит от настроек марафона)
+- Серия обнуляется
+- Игра остаётся доступной (можно получить другой челлендж)
+
+### Прохождение
+
+- Штраф в очках
+- Серия обнуляется
+- **Игра исключается из спина навсегда**
+- Все BonusAssignments удаляются
+
+---
+
+## Диспуты
+
+### Оспаривание прохождения
+
+Если диспут признан недействительным:
+1. Assignment → RETURNED
+2. Вычитаются все очки (прохождение + бонусы)
+3. Серия обнуляется
+4. Все BonusAssignments сбрасываются в PENDING
+
+### Оспаривание бонуса
+
+Если диспут признан недействительным:
+1. BonusAssignment → PENDING
+2. Вычитаются очки бонуса
+3. Proof данные очищаются
+4. Можно попробовать выполнить заново
+

+# ТЗ: Типы игр "Прохождение" и "Челленджи"
+
+## Описание задачи
+
+Добавить систему типов для игр, которая определяет логику выпадения заданий при спине колеса.
+
+### Два типа игр:
+
+| Тип | Название | Поведение при выпадении |
+|-----|----------|------------------------|
+| `playthrough` | Прохождение | Основное задание — пройти игру. Челленджи становятся **дополнительными** заданиями |
+| `challenges` | Челленджи | Выдаётся **случайный челлендж** из списка челленджей игры (текущее поведение) |
+
+---
+
+## Детальное описание логики
+
+### Тип "Прохождение" (`playthrough`)
+
+**При создании игры** с типом "Прохождение" указываются дополнительные поля:
+- **Очки за прохождение** (`playthrough_points`) — количество очков за прохождение игры
+- **Описание прохождения** (`playthrough_description`) — описание задания (например: "Пройти основной сюжет игры")
+- **Тип пруфа** (`playthrough_proof_type`) — screenshot / video / steam
+- **Подсказка для пруфа** (`playthrough_proof_hint`) — опционально (например: "Скриншот финальных титров")
+
+**При выпадении игры** с типом "Прохождение":
+
+1. **Основное задание**: Пройти игру (очки и описание берутся из полей игры)
+2. **Дополнительные задания**: Все челленджи игры становятся **опциональными** бонусными заданиями
+3. **Пруфы**:
+   - Требуется **отдельный пруф на прохождение** игры (тип из `playthrough_proof_type`)
+   - Для каждого бонусного челленджа **тоже требуется пруф** (по типу челленджа)
+   - **Прикрепление файла не обязательно** — можно отправить только комментарий со ссылкой на видео
+4. **Система очков**:
+   - За основное прохождение — `playthrough_points` (указанные при создании)
+   - За каждый выполненный доп. челлендж — очки челленджа
+5. **Завершение**: Задание считается выполненным после прохождения основной игры. Доп. челленджи **не обязательны** — можно выполнять параллельно или игнорировать
+
+### Тип "Челленджи" (`challenges`)
+
+При выпадении игры с типом "Челленджи":
+
+1. Выбирается **один случайный челлендж** из списка челленджей игры
+2. Участник выполняет только этот челлендж
+3. Логика остаётся **без изменений** (текущее поведение системы)
+
+---
+
+### Фильтрация игр при спине
+
+При выборе игры для спина необходимо исключать уже пройденные/дропнутые игры:
+
+| Тип игры | Условие исключения из спина |
+|----------|----------------------------|
+| `playthrough` | Игра **исключается**, если участник **завершил ИЛИ дропнул** прохождение этой игры |
+| `challenges` | Игра **исключается**, только если участник выполнил **все** челленджи этой игры |
+
+**Логика:**
+```
+Для каждой игры в марафоне:
+  ЕСЛИ game_type == "playthrough":
+    Проверить: есть ли Assignment с is_playthrough=True для этой игры
+              со статусом COMPLETED или DROPPED?
+    Если да → исключить игру
+
+  ЕСЛИ game_type == "challenges":
+    Получить все челленджи игры
+    Получить все завершённые Assignment участника для этих челленджей
+    Если количество завершённых == количество челленджей → исключить игру
+```
+
+**Важно:** Если все игры исключены (всё пройдено), спин должен вернуть ошибку или специальный статус "Все игры пройдены!"
+
+### Бонусные челленджи
+
+Бонусные челленджи доступны **только пока основное задание активно**:
+- После **завершения** прохождения — бонусные челленджи недоступны
+- После **дропа** прохождения — бонусные челленджи недоступны
+- Нельзя вернуться к бонусным челленджам позже
+
+### Взаимодействие с событиями
+
+**Все события игнорируются** при выпадении игры с типом `playthrough`:
+
+| Событие | Поведение для `playthrough` |
+|---------|----------------------------|
+| **JACKPOT** (x3 за hard) | Игнорируется |
+| **GAME_CHOICE** (выбор из 3) | Игнорируется |
+| **GOLDEN_HOUR** (x1.5) | Игнорируется |
+| **DOUBLE_RISK** (x0.5, бесплатный дроп) | Игнорируется |
+| **COMMON_ENEMY** | Игнорируется |
+| **SWAP** | Игнорируется |
+
+Игрок получает стандартные очки `playthrough_points` без модификаторов.
+
+---
+
+## Изменения в Backend
+
+### 1. Модель Game (`backend/app/models/game.py`)
+
+Добавить поля для типа игры и прохождения:
+
+```python
+class GameType(str, Enum):
+    PLAYTHROUGH = "playthrough"  # Прохождение
+    CHALLENGES = "challenges"    # Челленджи
+
+class Game(Base):
+    # ... существующие поля ...
+
+    # Тип игры
+    game_type: Mapped[str] = mapped_column(
+        String(20),
+        default=GameType.CHALLENGES.value,
+        nullable=False
+    )
+
+    # Поля для типа "Прохождение" (nullable, заполняются только для playthrough)
+    playthrough_points: Mapped[int | None] = mapped_column(
+        Integer,
+        nullable=True
+    )
+    playthrough_description: Mapped[str | None] = mapped_column(
+        Text,
+        nullable=True
+    )
+    playthrough_proof_type: Mapped[str | None] = mapped_column(
+        String(20),  # screenshot, video, steam
+        nullable=True
+    )
+    playthrough_proof_hint: Mapped[str | None] = mapped_column(
+        Text,
+        nullable=True
+    )
+```
+
+### 2. Схемы Pydantic (`backend/app/schemas/`)
+
+Обновить схемы для Game:
+
+```python

+            if self.playthrough_points is not None:
+                if self.playthrough_points < 1 or self.playthrough_points > 500:
+                    raise ValueError('playthrough_points должен быть от 1 до 500')
+        return self
+```
+
+### 3. Миграция Alembic
+
+```python
+# Новая миграция
+def upgrade():
+    # Тип игры
+    op.add_column('games', sa.Column(
+        'game_type',
+        sa.String(20),
+        nullable=False,
+        server_default='challenges'
+    ))
+
+    # Поля для прохождения
+    op.add_column('games', sa.Column(
+        'playthrough_points',
+        sa.Integer(),

+
+def downgrade():
+    op.drop_column('games', 'playthrough_proof_hint')
+    op.drop_column('games', 'playthrough_proof_type')
+    op.drop_column('games', 'playthrough_description')
+    op.drop_column('games', 'playthrough_points')
+    op.drop_column('games', 'game_type')
+```
+
+### 4. Логика спина (`backend/app/api/v1/wheel.py`)
+
+Изменить функцию `spin_wheel`:
+
+```python
+async def get_available_games(
+    participant: Participant,
+    marathon_games: list[Game],
+    db: AsyncSession
+) -> list[Game]:
+    """Получить список игр, доступных для спина"""

+
+    for game in marathon_games:
+        if game.game_type == GameType.PLAYTHROUGH.value:
+            # Проверяем, прошёл ли участник эту игру
+            # Исключаем если COMPLETED или DROPPED
+            finished = await db.scalar(
+                select(Assignment)
+                .where(

+---
+
+## Изменения в Frontend
+
+### 1. Типы (`frontend/src/types/index.ts`)
+
+```typescript
+export type GameType = 'playthrough' | 'challenges'
+
+export interface Game {
+  // ... существующие поля ...
+  game_type: GameType
+  playthrough_points: number | null
+  playthrough_description: string | null
+}
+
+export interface PlaythroughInfo {
+  description: string
+  points: number
+}
+
+export interface SpinResult {
+  assignment_id: number
+  game: Game
+  challenge: Challenge | null  // null для playthrough
+  is_playthrough: boolean
+  playthrough_info: PlaythroughInfo | null
+  bonus_challenges: Challenge[]
+  can_drop: boolean
+  drop_penalty: number

+  title?: string
+  download_url?: string
+  genre?: string
+  game_type?: GameType
+  playthrough_points?: number
+  playthrough_description?: string
+}
+```
+
+### 2. Форма добавления игры
+
+Добавить выбор типа игры и условные поля:
+
+```tsx
+// components/AddGameForm.tsx
+const [gameType, setGameType] = useState<GameType>('challenges')
+const [playthroughPoints, setPlaythroughPoints] = useState<number>(100)
+const [playthroughDescription, setPlaythroughDescription] = useState<string>('')
+
+return (
+  <form>
+    {/* ... существующие поля ... */}
+
+    <Select
+      label="Тип игры"
+      value={gameType}
+      onChange={setGameType}
+      options={[
+        { value: 'challenges', label: 'Челленджи' },
+        { value: 'playthrough', label: 'Прохождение' }
+      ]}
+    />
+
+    {/* Поля только для типа "Прохождение" */}
+    {gameType === 'playthrough' && (
+      <>
+        <Input
+          type="number"
+          label="Очки за прохождение"
+          value={playthroughPoints}
+          onChange={setPlaythroughPoints}
+          min={1}
+          max={500}
+          required
+        />
+        <Textarea
+          label="Описание прохождения"
+          value={playthroughDescription}
+          onChange={setPlaythroughDescription}
+          placeholder="Например: Пройти основной сюжет игры"
+          required
+        />
+      </>
+    )}
+  </form>
+)
+```
+
+### 3. Отображение результата спина
+
+Для типа "Прохождение" показывать:
+- Основное задание с описанием из `playthrough_info`
+- Очки за прохождение
+- Список дополнительных челленджей (опциональные)
+
+```tsx
+// components/SpinResult.tsx
+{result.is_playthrough ? (
+  <PlaythroughCard
+    game={result.game}
+    info={result.playthrough_info}
+    bonusChallenges={result.bonus_challenges}
+  />
+) : (
+  <ChallengeCard challenge={result.challenge} />
+)}
+```
+
+### 4. Карточка текущего задания
+
+Для playthrough показывать прогресс по доп. челленджам:
+
+```tsx
+// components/CurrentAssignment.tsx
+{assignment.is_playthrough && (
+  <div className="mt-4">
+    <h4>Дополнительные задания (опционально)</h4>
+    <BonusChallengesList
+      assignmentId={assignment.id}
+      challenges={assignment.bonus_challenges}
+      onComplete={handleBonusComplete}
+    />
+    <p className="text-sm text-gray-500">
+      Выполнено: {completedCount} / {totalCount} (+{bonusPoints} очков)
+    </p>
+  </div>
+)}
+```
+
+### 5. Форма завершения бонусного челленджа
+
+```tsx
+// components/BonusChallengeCompleteModal.tsx
+<Modal>
+  <h3>Завершить челлендж: {challenge.title}</h3>
+  <p>{challenge.description}</p>
+  <p>Очки: +{challenge.points}</p>
+
+  <ProofUpload
+    proofType={challenge.proof_type}
+    onUpload={handleProofUpload}
+  />
+
+  <Button onClick={handleComplete}>
+    Завершить (+{challenge.points} очков)
+  </Button>
+</Modal>
+```
+
+### 6. Редактирование игры
+
+Добавить модалку/страницу редактирования игры:
+
+```tsx
+// components/EditGameModal.tsx
+interface EditGameModalProps {
+  game: Game
+  onSave: (data: GameUpdate) => void
+  onClose: () => void
+}
+
+const EditGameModal = ({ game, onSave, onClose }: EditGameModalProps) => {
+  const [title, setTitle] = useState(game.title)
+  const [downloadUrl, setDownloadUrl] = useState(game.download_url)
+  const [genre, setGenre] = useState(game.genre)
+  const [gameType, setGameType] = useState<GameType>(game.game_type)
+  const [playthroughPoints, setPlaythroughPoints] = useState(game.playthrough_points ?? 100)
+  const [playthroughDescription, setPlaythroughDescription] = useState(game.playthrough_description ?? '')
+
+  const handleSubmit = () => {
+    const data: GameUpdate = {
+      title,
+      download_url: downloadUrl,
+      genre,
+      game_type: gameType,
+      ...(gameType === 'playthrough' && {
+        playthrough_points: playthroughPoints,
+        playthrough_description: playthroughDescription,
+      }),
+    }
+    onSave(data)
+  }
+
+  return (
+    <Modal onClose={onClose}>
+      <h2>Редактирование игры</h2>
+
+      <Input label="Название" value={title} onChange={setTitle} />
+      <Input label="Ссылка на скачивание" value={downloadUrl} onChange={setDownloadUrl} />
+      <Input label="Жанр" value={genre} onChange={setGenre} />
+
+      <Select
+        label="Тип игры"
+        value={gameType}
+        onChange={setGameType}
+        options={[
+          { value: 'challenges', label: 'Челленджи' },
+          { value: 'playthrough', label: 'Прохождение' }
+        ]}
+      />
+
+      {gameType === 'playthrough' && (
+        <>
+          <Input
+            type="number"
+            label="Очки за прохождение"
+            value={playthroughPoints}
+            onChange={setPlaythroughPoints}
+            min={1}
+            max={500}
+          />
+          <Textarea
+            label="Описание прохождения"
+            value={playthroughDescription}
+            onChange={setPlaythroughDescription}
+          />
+        </>
+      )}
+
+      <div className="flex gap-2">
+        <Button variant="secondary" onClick={onClose}>Отмена</Button>
+        <Button onClick={handleSubmit}>Сохранить</Button>
+      </div>
+    </Modal>
+  )
+}
+```
+
+### 7. Кнопка редактирования в списке игр
+
+```tsx
+// components/GameCard.tsx (или GamesList)
+{isOrganizer && (
+  <Button
+    variant="ghost"
+    size="sm"
+    onClick={() => setEditingGame(game)}
+  >
+    Редактировать
+  </Button>
+)}
+```
+
+### 8. Счётчик доступных игр
+
+Отображать количество игр, которые ещё могут выпасть при спине:
+
+```tsx
+// components/AvailableGamesCounter.tsx
+interface AvailableGamesCounterProps {
+  available: number
+  total: number
+}
+
+const AvailableGamesCounter = ({ available, total }: AvailableGamesCounterProps) => {
+  const allCompleted = available === 0
+
+  return (
+    <div className="text-sm text-gray-500">
+      {allCompleted ? (
+        <span className="text-green-600 font-medium">
+          Все игры пройдены!
+        </span>
+      ) : (
+        <span>
+          Доступно игр: <strong>{available}</strong> из {total}
+        </span>
+      )}
+    </div>
+  )
+}
+
+// Использование на странице марафона / рядом с колесом
+<AvailableGamesCounter available={gamesCount.available} total={gamesCount.total} />
+```
+
+---
+
+## Уточнённые требования
+
+| Вопрос | Решение |
+|--------|---------|
+| Очки за прохождение | Устанавливаются при создании игры (поле `playthrough_points`) |
+| Обязательность доп. челленджей | **Не обязательны** — можно завершить задание без них |
+| Пруф на прохождение | Тип указывается при создании (`playthrough_proof_type`) |
+| Пруфы на бонусные челленджи | **Требуются** — по типу челленджа (screenshot/video/steam) |
+| Прикрепление файла | **Не обязательно** — можно отправить комментарий со ссылкой |
+| Миграция существующих игр | Тип по умолчанию: `challenges` |
+| Дроп игры (playthrough) | Дропнутая игра **не выпадает** повторно |
+| Бонусные челленджи после завершения | **Недоступны** — только пока задание активно |
+| Счётчик игр | Показывать "Доступно игр: X из Y" |
+| События для playthrough | **Все игнорируются** — стандартные очки без модификаторов |
+
+---
+
+## План реализации
+
+### Этап 1: Backend (модели и миграции) ✅
+- [x] Добавить enum `GameType` в `backend/app/models/game.py`
+- [x] Добавить поля `game_type`, `playthrough_points`, `playthrough_description`, `playthrough_proof_type`, `playthrough_proof_hint` в модель Game
+- [x] Создать модель `BonusAssignment` в `backend/app/models/bonus_assignment.py`
+- [x] Обновить модель `Assignment` — добавить `game_id`, `is_playthrough`
+- [x] Создать миграцию Alembic (`020_add_game_types.py`)
+
+### Этап 2: Backend (схемы и API) ✅
+- [x] Обновить Pydantic схемы для Game (`GameCreate`, `GameResponse`)
+- [x] Добавить схему `GameUpdate` с валидацией

+- [x] Добавить API счётчика игр (`GET /available-games-count`)
+- [x] Добавить схемы для `BonusAssignment`, `PlaythroughInfo`
+- [x] Добавить эндпоинты для бонусных челленджей
+
+### Этап 3: Backend (логика спина) ✅
+- [x] Добавить функцию `get_available_games()` для фильтрации пройденных игр
+- [x] Обновить логику `spin_wheel` для обработки типов
+- [x] Для типа `challenges` — выбирать только невыполненные челленджи
+- [x] Обработать случай "Все игры пройдены"
+- [x] Обновить ответ SpinResult
+- [x] Обновить логику завершения задания для playthrough
+- [x] Добавить логику завершения бонусных челленджей
+- [x] Игнорирование событий для playthrough
+
+### Этап 4: Frontend (типы и формы) ✅
+- [x] Обновить типы TypeScript (`Game`, `SpinResult`, `BonusAssignment`, `GameUpdate`, `AvailableGamesCount`)
+- [x] Добавить выбор типа в форму создания игры
+- [x] Добавить условные поля "Очки", "Описание", "Тип пруфа", "Подсказка" для типа "Прохождение"
+- [x] Добавить API метод `gamesApi.update()` и `gamesApi.getAvailableGamesCount()`
+- [x] Добавить API методы для бонусных челленджей
+
+### Этап 5: Frontend (UI) ✅
+- [x] Обновить отображение результата спина для playthrough
+- [x] Обновить карточку текущего задания (PlayPage)
+- [x] Показ бонусных челленджей со статусами
+- [x] Бейдж "Прохождение" на карточках игр в лобби
+- [x] Поддержка пруфа через комментарий для playthrough
+
+### Этап 6: Тестирование
+- [ ] Тестирование миграции на существующих данных
+- [ ] Проверка создания игр обоих типов
+- [ ] Проверка редактирования игр (смена типа, обновление полей)
+- [ ] Проверка спина для playthrough и challenges
+- [ ] Проверка фильтрации пройденных игр (playthrough не выпадает повторно)
+- [ ] Проверка фильтрации челленджей (выпадают только невыполненные)
+- [ ] Проверка состояния "Все игры пройдены"
+- [ ] Проверка завершения основного и бонусных заданий
