Dogs did move on h4 and lose the game. Dogs does not have any moves, while Cats have (e1).

Invented by Chris Huntoon.

One player represents the Cats, the other, the Dogs. The game is played on an empty 8x8 board.

ANIMALS - On each turn, each player drops one of his pets into an empty cell. However, the cell where the new animal is dropped cannot be orthogonally adjacent to a different animal (i.e, no dogs and cats close to each other). Diagonally adjacent is fine.

GOAL - Wins the player that after there is no more valid moves, has more animals on board. The first play who can not make a move loses.

I added blocks to the game.
