This is Philos' version of a very difficult combination game. The game has five rules: 1) A tile may not be put on a space if they both have the same symbol
2) A tile may not be put on a space if any adjacent space contains the same symbol, either vertically, horizontally, or diagonally
3) Once a piece is laid down, you cannot use a tile with the same symbol as the one that has been covered.
4) Once a piece has been placed, it cannot be removed.
5) If no more moves are possible, the game restarts.
