About Math Crosswords: Number Equations in a Crossword Grid

Math Crosswords replaces words with numbers, turning the familiar crossword format into an arithmetic puzzle. Equations run across and down the grid, crossing each other so that a single cell must satisfy two equations simultaneously. Get that shared number right and both equations light up green. The game covers addition, subtraction, multiplication, and division across a large collection of levels, starting with simple sums and scaling up to larger grids as difficulty increases gradually. Every level has exactly one solution. Light and dark themes are available to suit your preference.

A daily puzzle keeps a streak going, and speed points, a leaderboard, and achievements give regular players something to chase. It works as a five-minute brain warm-up for adults and as mental math practice for kids.

How to Play Math Crosswords

Numbers sit in a panel beside the board, and the board holds equations with empty cells waiting to be filled. Drag a number directly into an empty cell, or select the number first and then tap the target cell. To remove a number already placed, tap the filled cell and it returns to the panel. A completed equation turns green when correct and red when wrong. The level is cleared once every equation on the board shows green.

A light bulb hint places one correct number when progress stalls. Finishing fast and without using hints earns the highest score. The best starting point is any cell where two equations intersect — those crossing cells have the fewest possible values that can satisfy both equations at once.

Controls

• Mouse: Drag numbers onto cells or click a number then click a cell; click a filled cell to return its number
• Touch: Drag numbers onto cells or tap a number then tap a cell; tap a filled cell to return its number
