About

Drop Sum is an 8-bit style math game for kids to practice addition. Drop Sum has 2 modes of play: Make 10 and Random 2–9. In Make 10 mode, kids must add falling blocks together to equal 10. In Random mode kids must add falling blocks together to equal a range of numbers 2–9. The goal of Drop Sum is to collect as many coins as possible by correctly adding together blocks to equal the target number. The game is over when a stack of blocks reaches the top of the screen. TIP: Stacks of blocks greater than 10 will become frozen and stuck!
