Math Crossword: Number Puzzle
A crossword made of numbers. Fill the grid so every row and column adds up.
The grid has sums instead of clues, and every digit you place has to make a row and a column come out right at once. Hundreds of boards across eight chapters plus a daily board, each checked by two independent solvers to have exactly one answer that can be reasoned out without guessing. No timer and no lives; free with ads, and optional help you can take by watching an advert.
What makes it different
- Every board has exactly one answer, and nothing needs a guess.
- No timer, no lives, and no energy meter to wait on.
- Plays fully offline — adverts are optional and rewarded only.
- Free, with nothing locked behind a purchase.
