MathRow

MathRow — Cross Sums Puzzle is a clean, offline logic puzzle game where you solve grid-based challenges by selecting numbers that correctly match row and column sums.

Train your brain with simple rules but deeply challenging gameplay. Every level is procedurally generated, meaning you’ll never run out of puzzles to solve.

🧩 Gameplay

Each puzzle consists of a grid of numbers with target sums shown on the edges. Your goal is to decide which numbers to keep and which to remove so that:

Each row matches its target sum
Each column matches its target sum

A single mistake costs a life, so think carefully before each move.
