Math Crossword
A crossword puzzle made of numbers: every clue is a sum. Fill in the missing values so every equation running through the grid checks out.
How it works
Every square sits at the intersection of two or more equations. The operators (+, −, ×, ÷) are always shown. Your job is just to work out which number makes every sum running through that square true at once.
Gentle onboarding
A short tutorial walks you through the very first sum before puzzles ramp up.
Five difficulty bands
Easy through Very Hard: bigger grids and fewer given numbers, never more complicated rules.
Daily Challenge
One puzzle a day, the same for everyone, with streak tracking to keep you coming back.
Endless mode
Pick a difficulty and get an infinite stream of freshly generated puzzles.
Stats that stick
Puzzles solved and best streak, so your progress feels visible over time.
