Mathematical Crossword
About Mathematical Crossword
Mathematical Crossword is a free online puzzle game from Gamepush that takes the familiar crossword grid and swaps letters for numbers and arithmetic symbols. Instead of filling in words, you place digits and operators (+, −, ×, ÷) into a grid so that every row and column reads as a correct equation from left to right and top to bottom. Puzzles are randomly generated, which means there's effectively an infinite supply of them, and you can set the difficulty to match your grade level and choose whether arithmetic symbols are included in the mix or left out for a simpler number-placement challenge.
Mathematical Crossword runs entirely in the browser with no download required, and it's fully playable on both computers and mobile devices using drag-and-drop or tap-to-place controls. It's built as a genuine brain workout rather than a fast-action game, rewarding careful logical thinking over speed, which makes it a solid pick for players who enjoy math puzzles, number games, or classic crosswords with a numerical twist.

How the Grid Works
Every empty box on the grid needs to be filled with a number or arithmetic symbol taken from the tray below the puzzle, and the game automatically checks your full set of answers once every square is filled in. The key rule to remember is that calculations always read from left to right and from top to bottom, just like a standard crossword reads across and down, so every completed row and column must form a mathematically correct equation. You're free to swap pieces around as much as you like before submitting, which makes it easy to experiment with different number placements until the equations line up.
Hints and Helpers
If you get stuck, Mathematical Crossword gives you five hints per puzzle — using one automatically places a random correct number for you, which is useful for breaking a deadlock without giving away the entire solution. The remove tool, shown as a basket icon, lets you pull a wrongly placed number or symbol back out of the grid, and the sort tool tidies up your remaining pieces so you can see your options more clearly on a crowded screen. Since puzzles are randomly generated, difficulty and layout vary each time, so leaning on hints occasionally is a normal part of clearing harder grids.
Tips for Winning at Mathematical Crossword
Start with the rows or columns that only have one or two empty cells, since those are the easiest to solve with certainty and narrow down your options elsewhere on the grid. Work out overlapping intersections carefully — a number placed at the intersection of a row and column has to satisfy both equations at once, so check both directions before committing. If you're new to the game, turn off arithmetic symbols in the difficulty settings and focus purely on number placement until you're comfortable, then reintroduce operators for a bigger challenge. Save your hints for genuine dead ends rather than using them early, since a well-timed hint can unlock an entire section of the grid.
How to Play Mathematical Crossword
- Set your difficulty — Choose a grade-based difficulty level and decide whether to include arithmetic symbols.
- Study the grid — Look at the empty cells and the numbers/symbols available in the tray.
- Place your pieces — Drag or tap-to-place numbers and symbols into the empty boxes.
- Check both directions — Make sure every row and column reads as a correct equation left to right and top to bottom.
- Swap as needed — Rearrange pieces freely until the equations work out.
- Use hints if stuck — Spend one of your five hints to place a random correct number.
- Complete the puzzle — Fill every square, and the game will automatically verify your solution.
