Shisen-Sho

[Birdie]

There is a cool game called Shisen-Sho. You have to match up 2 squares that are exactly alike. If they are able to connect they go off the board. Once there are no two squares that can connect with each other the game is over.

[EMH]

You forgot that the 2 squares must be touching, or can connect without another square blocking the way to get rid of them. (Hint: If you can't find another pair press "h" on your keybord, and it will show you another pair! :D )
