Sum Master is an engaging and challenging number puzzle game designed to enhance your mental arithmetic and logical reasoning skills. The objective is to select numbers within a grid so that the sums of each row, column, and colored region match the specified targets. Each puzzle has a unique solution, requiring players to carefully consider which numbers to include or exclude. The game offers a stimulating experience that combines fun with educational value.
Fans of casual will feel at home, and the puzzle elements give it extra range. Pick it up for a short break or settle in for a while — it runs well on phone, tablet, and desktop alike.
If you want to do well, keep this in mind: When you are stuck, undo the last move and look at the board again instead of forcing a fix. Work from the corners and edges inward — they usually have the fewest possible solutions.
