What Makes Crossmath Different From a Word Crossword

A normal crossword uses letters and clues. A crossmath number crossword uses arithmetic instead. Every row and column is a small equation with addition, subtraction, multiplication, or division, and the challenge is logical: place the right numbers so all equations agree at the same time.

• Pure logic and arithmetic — no vocabulary or trivia required.
• Every puzzle has exactly one solution, so progress is always fair.
• Difficulty scales from gentle 5x5 boards to expert 11x11 grids.
