# Trivia1

> Free multiplayer trivia and joke karaoke for bars, hotels, restaurants,
> and events. Browser-based, QR-code join, no app, no signup required.

## Game modes

- **Trivia Royale** (`https://trivia1.com/royale`) — free-to-play, single-elimination
  live trivia everyone plays at once; miss a question and you're out, and
  the last player standing wins. An always-on public game runs 24/7 at
  `https://trivia1.com/royale` (jump in instantly as a guest — no account — or sign in
  to save your score), plus bigger free scheduled games three times a day
  (1:00, 6:00 & 9:00 PM ET) at `https://trivia1.com/royale/live`. No host; it runs
  itself. Entry is free; a knocked-out player can spend tokens to buy back in.

- **Host your own game** (`https://trivia1.com/host`) — any free account can host;
  it is NOT a paid feature, and configuring a game is free. Running a
  game from the built-in question banks is free (a free account covers
  up to 30 players); tokens are spent only on optional extras —
  AI-generating questions on a custom topic, the metered self-running
  modes, and passes for larger crowds. Players join by code or QR — no
  login and no app required. Pick one of three modes when creating:
  - **Classic** — rounds of questions, cumulative scoring across rounds,
    host-paced from `/manage`. Free from the built-in banks; a game
    includes up to 30 questions and a one-time unlock raises that limit.
  - **Royale** — your own private single-elimination knockout; a wrong or
    missed answer knocks a player out, last standing wins. Metered per
    question in tokens while players are in.
  - **Infinite** — self-running rounds that roll continuously and reset
    scores each round, showing a round winner. A small start cost, then
    metered per question in tokens as it runs.

Tokens are earned by completing the short onboarding steps in your
dashboard, claiming a daily login bonus, and placing in Trivia Royale,
or bought in packs — there is no subscription. Players never pay to join.

## How to create a game via URL

Anyone — including an LLM agent suggesting a link to a user — can pre-fill
the host form with URL query parameters. The visitor still clicks Create,
so this is safe to share in chat replies or QR codes.

Hosting requires a free account: a signed-out visitor who opens a `/host?…`
link is sent to sign up (or log in) first, and the full deep-link is
preserved, so after signup they return to the pre-filled host form. Playing
a game (join by code / QR) needs no account.

### Trivia: `https://trivia1.com/host`

| Param | Type | Notes |
| --- | --- | --- |
| `title` | string ≤ 255 | Game name shown to players. |
| `venue_name` | string ≤ 255 | Bar / restaurant / event name. |
| `time` | int 5–1800 | Default per-question time limit in seconds. |
| `mode` | `custom` \| `answer_only` | Whether questions are multi-choice (default) or open-answer. |
| `topic` | string ≤ 500 | What to generate questions about. Sets `ai_queued` on the session. |
| `count` | int 1–50 | How many AI questions to generate when `topic` is set. |
| `difficulty` | `easy` \| `medium` \| `hard` | Difficulty for AI generation. |
| `category` | string ≤ 100 | Category name to tag generated questions with. |

AI-generation params (`topic`, `count`, `difficulty`, `category`) are
stashed into the new session's settings. After the host clicks Create,
the `/manage/{id}` page shows a banner offering one-click bulk generation
through the AI provider chain (Groq → Gemini → OpenAI → Anthropic).

### Joke Karaoke: `https://trivia1.com/joke/host`

| Param | Type | Notes |
| --- | --- | --- |
| `title` | string ≤ 255 | Game name. |
| `mode` | `random` \| `self_pick` \| `host_curated` | How jokes get assigned to performers. |
| `rate_window_seconds` | int 10–300 | Audience rating window after each performance. |
| `categories` | comma-list of ints | Joke category IDs to filter the draw to. |

### Opaque blob form

For URLs you don't want users to read (QR codes, marketing emails), pass
a base64-encoded JSON blob:

```
https://trivia1.com/host?settings=eyJ0aXRsZSI6IjgwcyBUcml2aWEifQ
```

Direct query params override fields decoded from the blob.

## Example deep-links

Casual game:

```
https://trivia1.com/host?title=Friday+Pub+Trivia&venue_name=Joe%27s+Bar
```

AI-generated quickstart:

```
https://trivia1.com/host?title=80s+Movie+Trivia&topic=80s+movies&count=10&difficulty=hard
```

Joke karaoke night:

```
https://trivia1.com/joke/host?title=Karaoke+Night&mode=self_pick&rate_window_seconds=45
```

## Programmatic control — MCP server

Trivia1 exposes a Model Context Protocol server at `POST https://trivia1.com/mcp` for
agents that need to create, manage, and tear down games end-to-end.
Protocol version `2025-03-26`. Bearer-token auth (`Authorization: Bearer
t1_…`); tokens are issued to any signed-in account at
`https://trivia1.com/account/api-tokens`.

Tools exposed (call `tools/list` for full schemas):

- `games_list` — List trivia (and future joke karaoke) sessions owned by the authenticated user, newest first.
- `game_get` — Get full state of a single trivia session by session_id.
- `trivia_session_create` — Create a new trivia session, optionally filling every round with questions in the same call. Each round takes an optional banks[] list, so one call can build "Round 2: 5 easy Star Wars + 3 medium Marvel + 2 hard Middle-earth". Call banks_list first for ids, pool sizes and difficulty spread. Returns session_id, join_code, host_token, plus a creation_import block showing what each bank actually contributed. Rounds with no banks[] are created empty — fill them later with bank_questions_import_to_session or trivia_questions_generate. Free users are limited to one game at a time — creating a new one hides the previous.
- `trivia_infinite_session_create` — Create a never-ending trivia session. Each round contains 20 randomly-selected non-duplicate questions; rounds auto-roll until 24h elapses or the host ends the game. Scores reset on each rollover so late-joining teams stay competitive. Returns session_id, join_code, host_token, manage_url, join_url, and the infinite block (started_at, expires_at, questions_per_round, bank_specs). Free for signed-in members.
- `trivia_session_settings_update` — Patch fields in a session's settings JSON (time limit, question mode, venue name, etc.).
- `trivia_session_end` — Mark a trivia session as completed.
- `trivia_questions_list` — List questions for a session, ordered by sort_order.
- `trivia_question_add` — Add a single multiple-choice question to a session.
- `trivia_question_update` — Edit fields on an existing question.
- `trivia_question_delete` — Delete a question from a session.
- `trivia_questions_generate` — AI-generate multiple-choice trivia questions for a topic and append them to the session. Routes through the AiChain (groq -> gemini -> openai -> anthropic).
- `trivia_teams_list` — List teams in a session with their scores and player counts.
- `trivia_team_add` — Add a host-created team to a session.
- `trivia_team_award_points` — Award (or deduct, with a negative value) bonus points to a team. Useful for trivia rule edge cases (creative answers, penalties).
- `joke_session_create` — Create a new Joke Karaoke session. Returns session_id, join_code, host_token, manage_url, join_url. Venue/Business feature (not on standard accounts).
- `joke_session_start` — Set a joke session to status=active. Idempotent.
- `joke_session_pause` — Set a joke session to status=paused.
- `joke_session_advance` — Close the current performance, pick the next joke + team (mode-dependent), and start it live. Returns the new performance or {ended:true} if no more can be drawn.
- `joke_session_skip` — Mark the current performance as skipped (no rating window) and advance.
- `joke_session_end` — End a joke session — closes any live performance and sets status=ended.
- `joke_categories_list` — List joke categories (id, slug, name, joke count).
- `joke_session_get` — Get full state of a joke session (settings, current performance, teams, recent performances).
- `joke_performances_list` — List performances in a joke session, ordered by position.
- `joke_teams_list` — List teams in a joke session.
- `category_list` — List trivia categories with bank-question counts. Read access for any authenticated token.
- `category_create` — Create a new trivia category. ADMIN ONLY. Slug auto-derives from name if omitted.
- `category_update` — Update a category. ADMIN ONLY.
- `category_delete` — Delete a category. ADMIN ONLY. Fails with 409 if the category still owns bank questions or rounds — reassign first.
- `bank_questions_list` — List questions in the global shared bank. Filter by category_id and/or difficulty. Pagination via offset+limit.
- `bank_question_create` — Add a question to the global shared bank. ADMIN ONLY.
- `bank_question_update` — Edit a bank question. ADMIN ONLY.
- `bank_question_delete` — Remove a bank question from the global catalogue. ADMIN ONLY.
- `bank_questions_import_to_session` — Copy matching bank questions into a session round. Two shapes: `difficulty` + `count` for a flat draw, or `difficulty_mix` ({"easy":4,"medium":4,"hard":2}) to build a ramp inside ONE round in a single call — tiers are appended easiest-first so the round plays as a curve. Questions already in the session are never drawn twice. 50 questions per call, whichever shape.
- `banks_list` — The catalogue of banks you can actually build a game from: the shared banks, the premium banks (flagged with whether you have unlocked them), and your own — each with its pool size and difficulty breakdown. Call this BEFORE trivia_session_create: bank ids are not category ids, and the catalogue is uneven enough that planning blind produces short or empty rounds (some premium banks hold no easy questions at all). Also returns your per-game question cap so a plan can be sized to fit.
- `custom_banks_list` — List the authenticated user's saved custom question banks with question counts.
- `custom_bank_create` — Create a new empty custom bank.

- `custom_bank_delete` — Delete a custom bank and all its questions.
- `custom_bank_question_add` — Add a question to a custom bank.
- `custom_bank_question_update` — Edit a question inside a custom bank.

- `custom_bank_save_from_session` — Snapshot a trivia session's questions (optionally one round) into a new custom bank for reuse later.
- `custom_bank_import_to_session` — Copy every question from a custom bank into a session round.
- `custom_bank_generate` — AI-write a brand-new, reusable custom question bank on a topic and save it to the caller's account. This is the premium builder the in-app chatbot uses — priced in tokens (a one-time unlock fee + a per-question rate, from config) and charged to the caller's REDEEMABLE balance; failed generations are refunded. Requires the server's CUSTOM_BANK_BUILDER_ENABLED flag.
- `admin_impersonation_link` — Mint a one-shot signed login URL as the target user. Hand the link to the user or click it yourself to debug their view. Burns on first click. ADMIN ONLY.
- `admin_generate_bank_questions` — Bulk-generate N multiple-choice trivia questions for a category and append to the shared bank. Idempotent (updateOrCreate by category + question_text). Routes through the AiChain. ADMIN ONLY.
- `admin_generate_bank_jokes` — Bulk-generate N jokes for a joke karaoke category and append to the joke bank. Idempotent (updateOrCreate by source + body_md). ADMIN ONLY.
- `admin_generation_jobs_list` — List recent AI-generation jobs (questions or jokes), newest first.
- `credit_balance` — Get the authenticated user's current AI credit balance.
- `admin_grant_credits` — Add credits to a target user (positive int). ADMIN ONLY. Use for refunds, promo grants, or seeding a test user.

## Constraints

Playing is free for everyone (no account). Hosting needs a free
account; there is no subscription — you pay per use in tokens.

- **Free account** — the only consumer tier. Up to 30 players per game;
  25 rounds and 30 questions per round to start (both rise as you level
  up via Quizmaster); all 10 preseeded categories; build-your-own custom
  banks; all three modes (Classic, Royale, Infinite); saved game
  history; and API/MCP access. In metered modes (Royale/Infinite) the
  host sees/reorders the next 10 questions.
- **What costs tokens** — running a Classic game from the built-in banks
  is free; tokens meter only AI question generation, the self-running
  Royale/Infinite modes, and re-entries in the public Trivia Royale.
- **Bigger crowds** — one-time Big-Room / Mega-Room passes raise the
  player cap for an event (no subscription).
- **Venue features** — TV-overlay branding, audience capture, embeddable
  widgets, and Joke Karaoke are venue/Business-tier capabilities, not
  part of the free consumer account.
