You are allowed to examine a set of bumpers for a short period of time. Then the bumpers go away and you have to choose which bucket will catch the ball.
If you guess wrong the game is over. If you guess right then you proceed to the next level where the time given to examine the board decreases.
There are 4 sizes to challenge you, small being the easiest.
