This game is interesting. I didn't get very high scores, but I still like the concept of the game!
Edit: I just realized that it was a "keep going as long as you can" game and I got 195. o-O

Click to change X to O and O to X. Try to make as many moves as you can without repeating a past position.
X or O determin what tiles you can click next.
For 9 tiles there are 512 possible positions (2 to the 9th power)
I don't know if 512 is possible to get to. My personal best is 173.
Comment and tell me how you did. Maybe one of you would be the first to solve this.
