Unsigned Int

Unsigned Int is a math-based puzzle game with two different play styles. The puzzles in the easy level are all about addition and subtraction. When trying to tackle difficult levels, which involve operations such as multiplication and division, you can find yourself scratching your head. Playing it is a piece of cake. Simply select the numbered items with your mouse. The action that is performed on the component that you click will decide how the sum is changed. For instance, if you click on an item that has the notation "+5" on it, five will be added to the total. On the other hand, if you click on an item that has the notation "-5" on it, five will be deducted from the total. You must prevent the sum from falling below 0 or rising above 20.
