About Crossmath Challenge

Crossmath Challenge is a number puzzle built around a crossword-style grid of equations. Tiles wait in a tray at the bottom, and you place them into empty cells so the math works both across and down. The rules are quick to learn, but each placement can affect more than one equation, making careful reasoning essential.

You can tap a tile and then tap a cell, or drag the tile directly into position. Undo removes your last placement, while Shuffle changes the tray order and Hint fills a cell automatically when you need assistance. Hints have limited use, so solving the grid yourself remains the main focus.

How to Play Crossmath Challenge

Select a number tile from the bottom tray, then tap an empty grid cell to place it.

Drag a tile straight from the tray onto a cell if that feels more convenient.

Use Undo for the latest move, Shuffle to reorder tiles, or Hint to auto-fill a cell.

Tips & Tricks

1Check both the across and down equations before committing a tile to a shared cell.
2Use Undo when one placement makes the surrounding math harder to complete.
3Save limited hints for cells where the remaining options are especially unclear.
