// Available games
Prisoner's Dilemma
Stay silent or betray? You and the AI choose simultaneously — the tension between individual gain and collective good defines this classic.
Ultimatum Game
The AI splits a pot of 10 points and names its offer. Accept or reject — but rejecting means you both walk away empty-handed.
Trust Game
You invest points that triple in transit. The AI then decides how much to return. A pure test of trust and reciprocity.
Stag Hunt
Coordinate to hunt a stag together for the big payoff, or play it safe and hunt a rabbit alone. A game of coordination under uncertainty.
Battle of the Sexes
Two players each prefer different outcomes but both prefer coordinating over conflict. Who will get their way without a fight?
Second-Price Auction
Bid on a prize. The highest bidder wins — but pays the second-highest bid. Dominance of truth-telling awaits.

AI is processing your response
You start with 10 points. Whatever you send triples in transit. The AI then chooses how much to return. Pure trust in action.
