Cross Number: Math Crossword

Fill the grid so every row and column balances. 200 cross-math levels, a shared Daily Challenge with streaks, and Endless runs — deduction over speed, fully offline.

Fill the empty cells so every equation balances — across and down. Cross Number is a math crossword: each row and each column is an equation, and one wrong digit breaks both. Every puzzle is generated on your device and checked for a single solution before you ever see it.

Most number games test speed. This one rewards deduction. Start from the digits you can prove, pencil in candidates where you can't, and feel the grid click into place. A timer runs on every board, but only your star rating cares about it — the puzzle itself waits as long as you do.

WHAT YOU GET

• 200 levels across Easy, Medium, Hard, and Expert — from gentle addition grids to 9×9 monsters mixing all four operations • A Daily Challenge that is the same puzzle for everyone that day, with a streak calendar showing every date you kept alive • Endless mode with a personal best to beat in each difficulty tier • Pencil notes and undo, so a wrong guess costs you seconds, not the whole grid • Error checking that lights up the exact row or column that stopped balancing • Stars, coins, and hints earned by playing — hold a streak for seven days and the game pays you 50 coins

PERFECT FOR

• Commuters who want a puzzle that fits a train ride and works in airplane mode • Sudoku regulars ready for grids where arithmetic joins the logic • Adults keeping mental math sharp without flashcard drills • Anyone winding down at night who prefers deduction to doomscrolling

WHY NOT JUST SUDOKU?

Sudoku asks where the numbers go. A math crossword asks what the numbers are — every digit you place has to survive both its row's and its column's arithmetic, so one compact grid works your calculation and your logic at the same time.
