Mind the Corners is a board game where the goal is to place as many of your pieces on the grid as possible. Each piece consists of 1 to 5 square blocks, and scoring is by the number of unplayed squares (lowest score wins). There is a simple rule for what moves are allowed: the new piece must touch one of the player's own pieces, but only at a corner. Each player's first piece is played at one of the corners of the board.

Play is adjustable: 2-4 players (any of which can be computer players), different board sizes, a variable number of randomly placed blocking squares, player colors, and whether piece placement is by dragging or selection.
