About Sum Square game:
Drop the numbers into the colored boxes such that the sum of the numbers equals the required number for each box. The levels start off easy but later levels can be very tough. See if you can use your addition and thinking skills to complete all 60 levels…….without using the solutions button on the main menu too much!
