Sum Master

Put your logic and number skills to the test in Sum Master. It is a grid-based puzzle game where every row, column, and colored area must match its target sum. Simple to learn but challenging to master, this brain-teasing game is perfect for fans of Sudoku, Kakuro, and other number-based logic puzzles.

Each level presents a single solution, making every move a matter of careful calculation—not guesswork.

How to Play

Sum Master challenges you to select the right numbers in a grid to match multiple sum targets at once. Here's what you need to know:

Row Sums: Each row must add up to the clue number on its right.
Column Sums: Each column must match the target shown at the top.
Colored Region Sums: Each distinct colored area has its own clue number, and the sum of your selections within that region must hit the mark exactly.
The puzzles start easy but quickly grow more complex, demanding logic, arithmetic, and spatial reasoning.
