Mathdoku: Sudoku meets math

336 hand-picked puzzles from 3×3 to 9×9. Add, subtract, multiply and divide your way through every cage. No ads, no account, works offline. Light and dark mode.

Mathdoku is a number logic puzzle for people who like Sudoku but want a little arithmetic in the mix.

Fill every row and column with the numbers 1 to N, with no repeats. Then make the cages work: each thick-bordered group of cells shows a target and an operation in the corner, and the numbers inside must add, subtract, multiply or divide to hit it. Every puzzle has a logical path to the end. No guessing required.

336 PUZZLES, SEVEN GRID SIZES Start on a 3×3 and work up to 9×9. Each size has 48 levels sorted from easy to hard. The first levels use addition only, then subtraction, multiplication and division join in one at a time, so the difficulty ramps up at your pace.

PLAY YOUR WAY • Notes: pencil a candidate into a cell while you think it through • Hints: three per level, each fills and locks a cell when you are stuck • Undo and erase for when you change your mind • Mistakes show in red the moment they happen, nothing is lost

CHASE YOUR BEST SCORE Scoring rewards speed and clean solving. Finish a cage to score, complete a row or column for a bonus, and skip hints for the biggest totals. Beat your best on any level, any time.

BUILT FOR FOCUS • No ads, no account, no internet needed • Light and dark themes, or follow your system • Available in 19 languages • Haptic feedback you can turn off • A short how-to-play tutorial if you are new to cage puzzles
