A crossword where every clue is arithmetic.
Instead of words, you place numbers. Every row and every column is an equation, and all of them have to come true at once. Move one number and the whole grid shifts under you.
Twelve categories. 1,200 boards. No timers, no lives, no account.
WHAT YOU GET
• Four grid sizes — 5x5 for a coffee break, 11x11 for the long ride home
• Three difficulties, switched right on the board without losing your place
• A puzzle of the day — the same board for everyone, everywhere
• Streaks, and streak freezes that cover for you when life gets in the way
• Pencil notes for the numbers you suspect but cannot prove yet
• Undo that walks back through every single move
• Row and column highlighting, so you stop counting squares with your finger
• One free hint on every board, for when you are genuinely stuck
• Best times per size and difficulty, and eleven milestones to unlock
• A collection that fills up board by board
• Light and dark themes
• Fourteen languages
• Fully offline — plane, metro, basement, anywhere
HOW IT PLAYS
Tap an empty cell, then pick a number from the tray below. Each number goes in exactly once. Check your work whenever you want, or just keep going until it clicks.
Wrong number? The cell shakes. Stuck? One hint is on the house. Changed your mind four moves ago? Undo has you.
THE DAILY BOARD
One math crossword a day, identical for every player on the planet. Solve it and your streak grows. Miss a day and a freeze you earned quietly covers the gap. One reminder, at the hour you pick, and not a notification more.
MADE FOR THINKING
No energy bar. No countdown. No popup begging you to come back. A math crossword is a thing you solve at your own pace, and this one is built to let you.
