About Crossmath Challenge

CrossMath is a fast-paced number puzzle that combines arithmetic with crossword logic. The grid is laid out like a crossword, but instead of words, it contains maths equations running across and down. Some cells are empty, and a tray of number tiles sits at the bottom. Your job is to place the right tiles so every equation is correct.

Because equations intersect, a tile has to satisfy both the horizontal and vertical sums it belongs to. That cross-checking is what makes it a puzzle rather than a worksheet – you can use one equation to narrow down another, just like letters in a crossword.

Tap a tile then an empty cell, or drag it directly into place. Simple to pick up and tricky to master, it's great for maths fans, students practising mental arithmetic, and anyone looking for a different kind of number puzzle.

How to Play Crossmath Challenge

  1. Tap or click a tile from the tray.
  2. Tap an empty cell to place it, or drag the tile there.
  3. Complete every equation across and down.

Crossmath Challenge Tips & Tricks

  • Start with equations that have only one missing number.
  • Use crossing equations to check your guesses.
  • Place tiles with unique values first.
