The abstract strategy game Puppycraft is surprisingly deep for its simple rules.
The object of the game is to advance your kitty to the opposite edge of the board. On your turn you may either move your chess or place a wall.
You may hinder your opponent with wall placement, but not completely block him off.
Meanwhile, he is trying to do the same to you. The first puppy to reach the opposite side wins.
In the beta test ,99% of the people lost to the evil dog.
Defeat the Dog, save the puppy world.
