Catch The Cat

A cat sits in the middle of a grid of dots. Every time you block a dot, the cat takes one step toward the nearest edge — and it is not guessing, it takes the genuinely shortest route out. Block the obvious escape and it turns and runs the other way. Win by sealing every path before it reaches the border. It looks trivial for about three moves, and then you realise you have been walling yourself into the wrong half of the board.

How to play

Tap a dot to block it. The cat moves one step toward the nearest edge after each of your moves. Think two moves ahead and cut off the wide side of the board first. Undo and Reset are under the grid.
