Okey

Okey for four players with the 106-tile set: numbers 1–13 in red, yellow, blue and black, two of each, plus two false okeys. A tile turned from the stack is the indicator (a turned false okey goes under the stack); the okey is the next number in its colour, and 13 makes 1 the okey. Okey tiles are wild and a false okey stands for the okey tile. The dealer’s right gets 15 tiles and starts by discarding; the others get 14. Play runs counterclockwise: take your left player’s last discard or draw from the middle, then discard to your right. Sets are one number in 3–4 different colours; runs are 3 or more of one colour in sequence (12-13-1 is allowed, 13-1-2 is not). Finish by melding all 14 tiles, or with seven identical pairs, and discarding the 15th. Everyone starts with 20 points: a normal finish costs every other player 2, a pairs finish or discarding an okey 4, both 8. On your first turn, showing a twin of the indicator costs each opponent 1. If the middle runs out the hand scores nothing. When a player reaches 0, the highest score wins.

Each browser adds its own encryption layer to the tile shuffle and only the tile’s holder removes the last layer, so neither the other players nor the server see your rack or the middle stack. Discards are revealed with decryption proofs, and a finish reveals the whole rack so every player can check the melds. After each hand all keys are revealed and every browser replays the original rules before points count. This is not an independently audited zero-knowledge shuffle; a player who withholds a key stops the hand without a result.

The computer players use simple local heuristics: they take a discard that joins their tiles, finish when they can and otherwise shed their loosest tile. They are practice opponents.
