Crossmath: Math Crossword

Crossmath is a math crossword puzzle game. Fill the grid by solving equations that cross and share numbers — every across and down line must be mathematically true.

Built for calm, focused play: no account required and works offline.

KEY FEATURES

Crossed equations

Shared cells must satisfy every equation they touch. One number, two directions, real logic — not guesswork.





Four difficulties

Easy, Medium, Hard, and Expert. Warm up with addition and subtraction; later puzzles introduce more multiplication and division.





100 campaign levels

Follow the Classic path from relaxed beginner boards to challenging Expert deduction.





Daily math crossword

Solve one fresh number crossword each day and build a streak on your own schedule.





Practice by difficulty

Jump into Easy, Medium, Hard, or Expert whenever you want a specific challenge — not only the next campaign level.





Endless mode

Stages keep coming. How far can you go?





Number bank

Tap an empty cell, then choose from the numbers used in that puzzle. Remaining counts show how many times each value still needs a home.





Hint, Undo & Check

Reveal one correct number, reverse a move, or scan filled cells for mistakes. Finish cleanly for up to three stars.





Progress on your device

Track statistics and achievements, choose light or dark themes, and use large numbers or high contrast for comfortable play. Your progress stays local on your device.

HOW IT WORKS

1. Open a puzzle — a crossword of numbers and operators.



2. Tap an empty cell and choose a number from the number bank below the board.



3. Complete every equation. Intersecting lines share values, so each number must work in both directions.



4. Remember the order of operations: multiplication and division come before addition and subtraction. Division always results in a whole number.



5. Fill the entire board to finish the puzzle. Stars reflect how cleanly you solved it.

• Adults who want a quiet and relaxing number puzzle.

FAQ

Is this a word crossword?

No. You place numbers so every equation is mathematically correct.





Do I need to be great at maths?

No. Easy puzzles are gentle and approachable. Expert puzzles are denser and use more multiplication and division.





Does it work offline?

Yes. You can play offline, and your progress is saved on your device. No account is required.





Is it the same as Kakuro or Sudoku?

No. Kakuro uses block sums, and Sudoku uses digit placement rules. Crossmath uses complete arithmetic equations that cross and share numbers.





Are there hints?

Yes. Each puzzle includes a small hint allowance, along with Undo and Check tools.
