Tower Math - (by Dan Russell-Pinson)
Tower Math is a unique math app that makes practicing math fun by combining the excitement of tower defense games with arithmetic.
In Tower Math, the numbers have been turned into monsters and it's up to the player to save them. To break the spell, children must build magic towers by solving math problems. Players are encouraged to work at their highest level because solving more difficult problems results in more powerful towers. There are three types of towers to choose from: Cannon, Lobber and Lightning. Each tower type has its own unique abilities. There are also two special powers, freeze ray and magic rain, that players can use after successfully answering math problems.
