Cobacoli is one of many abstract puzzles created by flash developer Tonypa. In each level of this game, you are presented with a set of colored balls and one white ball. You can launch the white ball around the board to bounce of the walls and colored balls When a colored ball touches a wall of the same color, it is removed from play, and the level is over when all colored balls are gone. However, if the white ball touches a colored wall, you lose a shot. Also, the more times the white ball bounces off of walls and balls, the smaller and weaker it becomes, making it slower and harder to move larger balls.
While the main goal is to complete every level, you are also given a score for each level based on the shots you had left and the level completed. The game ends when you finish the final level, or when you run out of shots on a level.
