Friends join from their own ChatGPT chat or from a browser link on any phone. Each round everyone gets the same quirky theme (\"A cat running a bakery on Mars\", \"Your hometown as a video game boss level\") plus a secret twist of their own (\"make it look like a 1950s cereal box\", \"hide a rubber duck in it\"). The card shows the exact prompt to ask for. Each player asks their own ChatGPT to draw it and submits the picture; browser players choose a picture from their device.\n\nWhen everyone is in, the pictures appear as an anonymous gallery and each player votes for a favorite (not their own). Then a quick bonus: everyone guesses which secret twist went into the top picture. The reveal shows who drew what, every twist, and the votes. Each vote received is worth 2 points and a right twist guess is worth 1. After 3 or 5 rounds the final card crowns the winner with the picture of the game.\n\nThe pictures are made by each player's own ChatGPT; the game only carries them to the table. The host can skip ahead when someone is away. Rooms and their pictures are deleted 12 hours after the last move.", "category": "Entertainment", "defaultPrompt": [ "Start an AI Art Battle, I'm Dana", "Join Huddle AI Art Battle game KXQF as Sam", "Draw my art battle picture and submit it" ], "capabilities": [ "Every player's own ChatGPT draws their picture from a shared theme", "A secret twist per player, worked into their picture", "An anonymous gallery and a vote for the favorite", "A bonus guess: which twist made the top picture?", "Players join from their own ChatGPT chat or a browser link", "Live cards: pictures, votes and scores update on every screen" ], "logo": "https://games-worker.demos.42a.ai/art-battle/icon.svg", "websiteURL": "https://games-worker.demos.42a.ai/art-battle/", "supportURL": "https://games-worker.demos.42a.ai/support", "privacyPolicyURL": "https://games-worker.demos.42a.ai/privacy", "termsOfServiceURL": "https://games-worker.demos.42a.ai/terms", "developerName": "42a" }, "keywords": [ "ai art battle", "ai drawing game", "image generation party game", "draw with ai and vote", "art contest with friends", "picture prompt game", "multiplayer drawing game", "ai art competition" ], "tools": [ { "name": "start_art_battle", "title": "Start AI Art Battle", "annotations": { "readOnlyHint": false, "destructiveHint": false, "openWorldHint": false, "idempotentHint": false } }, { "name": "join_art_battle", "title": "Join AI Art Battle", "annotations": { "readOnlyHint": false, "destructiveHint": false, "openWorldHint": false, "idempotentHint": false } }, { "name": "art_battle_status", "title": "AI Art Battle Status", "annotations": { "readOnlyHint": true, "destructiveHint": false, "openWorldHint": false, "idempotentHint": true } }, { "name": "play_art_battle", "title": "Submit, Vote or Guess", "annotations": { "readOnlyHint": false, "destructiveHint": false, "openWorldHint": false, "idempotentHint": false } }, { "name": "art_battle_host", "title": "Host Controls", "annotations": { "readOnlyHint": false, "destructiveHint": false, "openWorldHint": false, "idempotentHint": false } } ], "dataSources": [], "review": { "positiveTestCases": [ { "description": "Host starts a game", "prompt": "Let's play AI Art Battle, I'm Dana", "tools_triggered": [ "start_art_battle" ], "expected_behavior": "A lobby card with a 4-letter code, a join link and Dana as host; the text gives her player key." }, { "description": "A friend joins with the code", "prompt": "Join Huddle AI Art Battle game DEMO as Riley", "tools_triggered": [ "join_art_battle" ], "expected_behavior": "Riley's own player key and the lobby with Dana, Sam and Riley." }, { "description": "Host starts round 1: a theme and a secret twist", "prompt": "Everyone is in, start the art battle", "tools_triggered": [ "art_battle_host" ], "expected_behavior": "Round 1 drawing: the theme, Dana's own secret twist and the exact prompt to ask ChatGPT, plus Choose my image." }, { "description": "The last picture (generated in ChatGPT) opens the gallery", "prompt": "[after ChatGPT generated the picture] Submit this to the art battle", "tools_triggered": [ "play_art_battle" ], "expected_behavior": "The anonymous gallery opens with 3 pictures; Cleo's is marked as hers and she can't vote for it." }, { "description": "The last vote opens the twist bonus", "prompt": "I vote for picture A", "tools_triggered": [ "play_art_battle" ], "expected_behavior": "Picture A (Nia) wins with 3 votes; the bonus asks which of 5 twists made it." } ], "negativeTestCases": [ { "prompt": "Draw me a cat running a bakery on Mars.", "expected_behavior": "Does not call Huddle AI Art Battle: A plain image request with no game: ChatGPT draws it directly." }, { "prompt": "Rate this painting I made out of 10.", "expected_behavior": "Does not call Huddle AI Art Battle: Art critique is a chat task, not a multiplayer game." }, { "prompt": "Let us play a game where I sketch something and you guess what it is.", "expected_behavior": "Does not call Huddle AI Art Battle: A one-on-one sketch-and-guess game is different; this game is a group vote on AI pictures." } ] } }
