A fun little puzzle game. Relies heavily on the player's ability to see several turns into the future. I'm no good at that kind of puzzle, but still managed to beat the AI with an advantage of over 100 points by picking the spots that would bounce the most.
If you're looking for things to promote replay-ability, I'd say add a ton of optional rulesets. The ability to change how turn order works or how claiming squares work could turn it into a great party game.
