With the help of wise Peter Pig, kids practice sorting and counting coins to earn money for their “banks”—all the while learning fun facts about U.S. currency. This game is a tribute to Pi (also known as 3.14). The digits of Pi form the different stages of the game, and your job is to think your way through to the last digit in the best possible way. Count the number of sheep on the screen. This game is for those with good observation.
