Cat Sudoku is a free, cat-themed version of classic number Sudoku. Fill the empty squares so each row, column and 3×3 box contains the digits 1–9 exactly once. Choose Easy, Medium or Hard, then tap a square and a number. On a computer, you can also use the number keys and arrow keys. Each puzzle has one solution and three hints. Undo and erase help you revise your moves, while red numbers show incorrect entries. Your game saves in this browser, so you can refresh and keep going. No download or account is needed.
