It's a good game. Good grafics and good gameplay. Some ideas is to make the AI not so smart for the first few eg no checkerboard and to add a story to this.
The only way I got past it waas to get new hardware. IF YOU CAN'T GET ON even if refresh etc. It will be the computer remembering the failed game and so you need to clear data of that game.
Great game. easy when you think about it.
This should not have achievements as the last puzzle requires you to either change the time or wait to midnight.
