## What is Arithmix?

Sudoku meets math. Fill the grid so every row, column and box has each number once, and every cage hits its target with +, −, × or ÷.

Start small on 4×4 and 6×6 boards while a friendly coach shows you the ropes, then grow into full 9×9 killer sudoku. Every one of the 100 levels has exactly one solution, so you never have to guess.
