Challenge your brain and hone your math skills in Sum-It! Add your way through the board to uncover a path that connects the target numbers. Each puzzle is unique and you'll find varying levels of difficulty. You can choose free play mode or play against the clock in timed trials.
HOW TO PLAY
Each puzzle has a target value as noted by the circled numbers. You begin in the top left corner and create a path to the bottom right corner, adding each square's value to your total as you proceed. The goal is to match the target value. You can move vertically and horizontally, but not diagonally.
