Okey (pronounced "okay") is a tile-based game, very popular in Turkey. It is almost always played with 4 players, though in principle can be played with two or three. It is very similar to the game Rummikub as it is played with the same set of boards and tiles but with different rules. The game apparently evolved from the original Rummikub through cultural contacts of Gastarbeiter in Germany. In Turkey and among Turkish communities abroad, it is very popular not only at homes but also at coffeehouses (visited mostly by men).
