The game is quite mathmatical so: If you get the entrie grid
full of noughts, instead of crosses, then simply press each
tile in order in a clockwise spiral inwards. This will turn
them into crosses. With a group of four tiles (2x2), pressing
each one in turn will reverse them completely and have no effect
on the other tiles around them. eg. OO XX OO becomes XX OX XO XO
becomes OX XX OO OO becomes XX etc…
