Okey is a traditional Turkish game, similar to Rummikub and Mahjong.
Players manage their hand to make runs and sets. The first one to use all of their pieces wins the game.
Suits come in 4 colors and run from 1 to 13. Notably, runs (of the same suit) can end with a 1 tile if they contain a 13 tile.
The game needs paying careful attention on the opponent's discarded pieces and plan new series according to them, as there is only a pair of every piece.
The game's namesake is the wild "Okey" tile, chosen randomly between the regular tiles at the start of every round.
Depending on the last tile a player discards to win a round, they score different amounts of points- finishing by discarding a regular tile is worth 2 points, but discarding an Okey tile is worth 4 points. An "indicator" tile is used to determine the Okey every round, and if someone has the identical indicator tile in their starting hand, they score an extra point.
