Cool Ball

Launch small balls and clear the bricks in each level to pass the level and get rewards.
After all the small balls are launched and hit the bricks, until they return to the launching position is called a round. There is a number on the bricks in the level, which indicates the current brick's points. The ball hits the brick once, and the brick point is reduced by one. The brick disappears when the number of brick points is reduced to 0.
At the end of a round, the scores of the current round are settled and accumulated to the scores of this level. The calculation of the score in this round is related to the number of points and bricks removed in this round. When eliminating the same points, clearing more bricks will get a higher score.
Pass the level for the first time, or get a historical high score by playing the same level, you will be rewarded with a UNDO item. Use a UNDO item to return to the state of the previous round. You can continue to use the UNDO item to roll back multiple steps.
