Sum Master
4.1 / 5(697 Votes)Instructions
Add up the numbers! In each grid, there is a number at the top of each column and at the end of each row. Your task is to select the numbers in the grid that add up to those target numbers.
Tap on a number to select it. If it’s incorrect, you'll lose a heart. If you see a number in the grid that shouldn’t be part of the total, tap on the eraser to remove it and help narrow down your choices.
If you get stuck, tap on the lightbulb to reveal one correct number.
On higher difficulty levels, the grid will turn into different colors. There will be a number in the corner of one of the cells in the grid. This number is how much the colored group can add up to - so if you choose a number that goes beyond what was added, you'll lose a heart!
