Dots and Shapes is a computer/table/phone variant of the pencil-and-paper game Dots and Boxes. It can be played on an original square grid, or on triangle or hexagon grids. The game starts with an empty grid of dots. The players take turns adding a single horizontal or vertical line between two unjoined adjacent dots. A player who completes the last side of a 1×1 box earns one point and takes another turn. The game ends when no more lines can be placed. The winner is the player with the most points.
