Rock paper scissors
The computer studies your patterns and predicts your next move. Humans are worse at being random than they think.
Frequently asked questions
How does the AI predict my moves?
It keeps a table of what you played after each pair of your previous moves (a second-order Markov model) and counters your most likely next throw. With no data it plays randomly, so the first few rounds are fair.
Why do I lose more the longer I play?
Because real people fall into rhythms: repeating winners, switching after losses, cycling rock-paper-scissors in order. Every habit becomes data. Beating the AI long-term means genuinely random play, which humans are famously bad at.
What is the best strategy?
Against a pattern-learner, true randomness is optimal and yields 33/33/33 over time. Try using something external as your randomizer (seconds on a clock, dice) and watch your loss rate drop.
