Bluff the bot

Three-card poker against a bot. Read its habit, then make the right decision. As many as you can in 60 seconds, each one scored the moment you answer.

How it works

1. Deck J, Q, K. You each ante 1 chip and get one card; the higher card wins a showdown.
2. Each round is one decision: check or bet 1, or, facing a bet, call 1 or fold. The best move scores 10; the other costs 3.
3. Often you're told the bot's habit, like "bluffs with every J". Use it. Otherwise it plays a balanced game.
4. Rounds get harder as you improve: from clear calls and folds to spots worth a fraction of a chip.

It trains judging a decision by its expected value, not its result. After every round you see the best answer and why.
