Bonus

Bonuses are stages in Alleyway that appear after completing a stage with an Advancing Block Screen pattern. The stage number for these stages is the same as the stage they appear after. Breakable blocks are arranged in such a way that they resemble characters from Super Mario Bros. In total, there are eight Bonuses.

Bonus Stage is the fourth and last pattern in Alleyway in which the ball goes through breakable blocks while destroying them. The stage ends after every breakable block is destroyed, the ball touches the bottom of the screen, or the time runs out. The player cannot lose a life on these stages. Bonus Stage pattern also introduces a Time Limit. If all the breakable blocks get destroyed before the time runs out, the player will receive 1500 points.

After a Bonus is completed, the next stage will have a Normal Block Screen pattern.
