Block your opponents blocks.
How to Play
The idea is to block you opponent's blocks!
Your first block must be placed in a corner.
All future blocks have to be placed corner-to-corner with one of your existing blocks.
You cannot be edge-to-edge with your own blocks, but can be edge-to-edge with opponent's blocks.

You win when your opponent can no longer add blocks and you still can.
If you are both stuck, higher score wins.
