Oli 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. Play Black plays first, then turns alternate. On your turn, cover a 1x1, 1x2, 1x3 or 2x2 empty area of the board with stones of your color. At the end of your turn, for any two diagonally adjacent stones of your color there must be another stone of your color adjacent to both, and there must be no 2x3 areas consisting of two empty points, two black stones a knight's jump away from each other and two white stones a knight's jump away from each other. You win if there is a chain of orthogonally connected stones of your color touching the two opposite board edges of your color. If you have no moves available on your turn, you must pass. Passing is otherwise not allowed. There will always be a placement available to at least one of the players. 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 designer
