Okimba is a drawless connection game for two players: Black and White. It is played on the intersections (points) of an initially empty square grid (board). The top and bottom edges of the board are colored black; the left and right edges are colored white. A naked diagonal is a pair of like-colored, diagonally adjacent stones with no other like-colored stone adjacent to both. Black plays first, then turns alternate. On your turn, place a stone of your color on an empty point. There must never be more than one naked diagonal on the board. You cannot pass your turn unless you have no legal moves. You win if there is a chain of orthogonally connected stones of your color touching the two opposite board edges of your color. To make the game fair, White will have the option, on their first turn only, to swap sides with Black instead of making a regular move. —description from the designer
