About This Game

CrossMath Challenge fills the gap between crosswords and sudoku by making equations the answer. A crossword-style grid shows math statements with gaps in them, and a tray of number tiles waits at the bottom of the screen. Drag tiles into place until every line reads true across and down — addition here, multiplication there, and where they intersect is where the real thinking starts. Because one tile affects both an across and a down equation, every placement is a small logic exercise. Undo erases mistakes, shuffle resets the tray, and a limited hint auto-fills a cell when you are truly stuck. Fast to start, hard to put down. Play free in your browser on phone or desktop.

How to Play

Tap a number tile from the tray, then tap an empty cell in the grid to place it — or drag the tile directly onto the cell. Equations must read correctly both across and down. Made a mistake? Tap Undo to remove your last tile. Shuffle reorders the tray when you want a fresh view, and Hint auto-fills one cell, though uses are limited. Solve every equation on the board to complete the puzzle.
