Cross Sums

Put your logic to the test in this relaxing and challenging number grid puzzle game. Each level gives you a grid of numbers and target sums for every row and column. Your goal is to decide which numbers belong in the final solution and which numbers should be removed.

Use the Play State toggle to switch between marking numbers that belong in the solution and removing numbers that do not. Every tap matters: choosing the wrong action costs one of your three lives, so think carefully before making a move.

As you solve puzzles, the game tracks your time and lets you progress through Easy, Medium, and Hard difficulty levels. Each new level brings a fresh grid challenge designed to sharpen your logic, concentration, and problem-solving skills.
