To achieve victory on this board of squares, you must overwhelm the center! The object of the game is to locate three of your own tiles in the centre row on a 5x5 grid. Players take turns to do one of: place a tile, move a tile, or use a tile's special power. The total value of tiles permitted in any row is 8, constraining both players. Tiles are double-sided, and you are not permitted to examine the back of an opponent's tile before a special power flips it.
