Like a pinball machine, bouncing the Papa Pear's from your shooter on as many pins and objects as possible, before it lands in one of the buckets below, will win you points.
Different elements on the game board score different values, so be sure to see what scores highest for you and focus on the areas which give the best results.
The aim is to earn enough points to win at least one star, as you need at least one to go to the next level. Each new level gives you more objects to bounce on, which means more points to gain!
