Minimalistic mathematical puzzle in which there is a board with numbers. Every row or column is a mini puzzle itself. The goal is to make the sum of numbers in each row and column be equal to the number in the box. What you have to do is to remove some numbers from the equation by clicking on them. It sounds simple but requires a lot of thinking.
