When math attacks, everyone is at risk. Especially since this game is a very strategic puzzler. In order to win you have to clear all of the tiles, but to do so will take some forethought. You have to plan your counterattack or you may be left with tiles that are unusable. The game is simple: pick a numbered tile, then pick an operator (i.e. plus, minus, etc). Then pick another number. Finally, pick the resulting number. So if your first number was 2, your operator was +, and the second number was 2, the resulting number would have to be four. When you get the equation right, those tiles disappear.
