How to Play Rock Paper Scissors Against AI
Pick your opponent

Throw your hand

Frequently Asked Questions
Is the AI actually predicting my throws?
Yes. Before each round the model receives your complete throw history for the match (never your current throw) and is asked to predict what you will play next and counter it. Your current throw is only compared after the AI has committed.
Is playing really free?
Yes. Everyone gets three free games per day across all our AI games. No signup, no credit card, no downloads. The limit resets every 24 hours.
Can rock paper scissors even be won against an AI?
Absolutely. If you throw truly randomly, nobody can predict you. But most people cannot stay random, and that is the whole fun. Beat the predictor by breaking your own habits.
Which AI models can I play against?
The model list is fetched in real time from OpenRouter, including GPT, Gemini, Claude, Grok, DeepSeek, Qwen, Llama and more. New models show up automatically as they are released.
What happens in watch mode?
Two models play each other, each trying to predict the other from the round history. It is chaos, and occasionally one really does find a pattern.
