Mathrid: Math Crossword

500 hand-crafted math crossword puzzles across five difficulties, plus a fresh Daily Challenge every day. Every grid is a one-of-a-kind shape. No sign-up, fully offline.

A crossword made of numbers. 500 puzzles — no two shapes alike.

Mathrid turns simple arithmetic into an addictive logic puzzle. Every row and every column of the crossword grid hides a math equation — drag the number tiles into the blanks so all of them add up at once. Easy to pick up, genuinely clever to master, and calm enough to enjoy anywhere.

You never guess — you reason. Place one number and a whole line locks in green, pointing you to the next move. That chain of little "aha" moments is what makes this math puzzle so hard to put down.
