Math Crossword

Math Crossword is a crossword puzzle where every clue is a sum. Numbers cross, equations interlock, and every square you fill has to make every equation running through it true.

HOW IT WORKS
Operators are always shown. You only ever fill in numbers. Work out what fits, tap the square, type the digit. Simple to pick up, satisfying to untangle.

A GENTLE START, THEN A REAL CHALLENGE
A short tutorial eases you in with your very first sum. From there, puzzles scale from Easy to Very Hard: bigger grids, fewer given numbers, more equations to juggle at once.

DAILY CHALLENGE
One puzzle a day, the same for everyone. Come back and keep your streak alive.

ENDLESS MODE
Pick a difficulty and keep going. A fresh puzzle generates the moment you finish the last one.

TRACK YOUR PROGRESS
Stats keep count of puzzles solved and your best daily streak, so you can see yourself getting sharper.
