Sum Square is a very intelligent numerical game designed to test your logical and mathematical abilities. The objective of this game is quite simple, although it becomes difficult to achieve with progression. All you have to do is insert numbers in those colored squares whose sum should be equal to a particular number.
There is a grid of overlapping colored squares at each level. Each square requires a particular number to be achieved through the placement of appropriate numbers within it. However, what makes the game more difficult is the overlapping portion of the squares; a particular number can influence more than one square at the same time.
This app provides 60 levels and becomes harder and harder as you progress. The first few problems teach you the rules, but the next steps will require some thinking to make your next move right. Otherwise, you will have a situation where one block cannot go well with another.
Drag and drop the numbers using your mouse or touch buttons.
Place numbers in the game grid to help achieve the sum for the colored blocks.
Tap on the numbered boxes on top of the screen if you wish to target a certain block, which would be particularly useful in harder levels where sections overlap.
Rather than placing the digits at random, think about what each digit would mean for the total that is needed in other boxes.
If a box requires a certain total, then there are only certain digits that would be needed to achieve this total.
Although you have access to the solution button, using it too frequently takes the fun out of solving the puzzle yourself.
