Mathematiles is a simple, but challenging, game of numbers which is sure to keep your mathematical mind on its toes. Give your calculator a rest and find among the tiles a pair which will add, subtract, multiply, or divide to equal the target number. Each level has a required number of equations to find within the time limit in order to move on. Find as many as possible to maximize your score. This is a demo version of Mathematiles which includes ten initial levels, and only allows for local scoring. A full version will be made available soon which will include many additional levels, and global scoring so you can compete against your friends (or foes).
