anticorners

How to Play

On your turn, click on an anticorner position to remove the hook at that position:

• An anticorner is a cell (i,j) where both the partition boundary drops at row i AND the conjugate boundary turns right at column j
• Anticorners are highlighted in red when it's your turn
• Removing a hook at (i, j) removes all cells (x, y) where x ≥ i and y ≥ j
• The player who makes the last move wins
