Checkers, and a game called lights off I think... The checkers game is super hard because the computer always makes the most logical decision.. it kicks my butt anyway..
the game lights off is where there is a grid of lit squares and every time you touch a square it alternates from on to off and all of the squares touching it do the same thing, and the objective is to turn all the lights off... it's pretty hard, but you have to think, which i like..
that's all i have so far.
anyway, it's a pretty cool site to offer so many free games!!
