PoolBall is a sport-like (and ad-free) game which is somehow a mixture of pool, hockey and soccer: basically two teams of disks that can be moved over a field try to score by pushing a smaller disk inside a score area.The game is turn-based and the rules very easy to learn, but still the game can be challenging.This is the free version: you can play a match against a friend or the computer, but you cannot choose the computer skill level or modify the teams.
