Xorlix for Palm

From Keith Batten:

Xorlix is a pair of puzzle games which you toggle tiles in an attempt to clear the screen. The first game mode is similar to the lights out game. When you tap a tile, all of the tiles in that column and row are toggled, for you computer people it uses an XOR operation, get it. Try to do this in as few moves as possible. The second game mode is similar in that when you click a tile, others are toggled. The difference is that the game board is much larger, and instead of toggling many tiles, only the tile itself and the tiles above, below, right and left of it are toggled. If you beat a level with moves remaining you may get some bonus moves.
