Wander and Chelle harken back to their childhoods and start adding to defend their castles in The Counting Kingdom. Developed by Little Worlds Interactive, The Counting Kingdom is an adorable tower defense/puzzler targeted at kids ages 6 - 10 or so. It's clever, adorable, and very simple, so if you are/you have a kid that age, then this game will be a fun way to polish their math skills. People older than that age range may also find it fun/adorable, but I wouldn't recommend it for the challenge in that case. Buy it on steam:
