About Calcudoku · Sudoku-like Puzzle
Enjoy Calcudoku, a fun number puzzle game that tests your math and logic! If you like Killer Sudoku puzzles, you will love Calcudoku!
About Calcudoku number puzzles:
Every Calcudoku has a single solution that can be reached logically. Like Sudoku and Killer Sudoku, fill in the grid such that no two digits repeat in any column or row. Use the shapes in the grid as your guide. Each shape contains a number equaling the product of the shapes' digits. For example a shape with three cells containing the number 6 may have cell values 1, 2 and 3, as 1 × 2 × 3 = 6. Challenge yourself further with larger grids for experts, up to 9x9 size!
Calcudoku offers thousands of fun number puzzles with features to help you solve each puzzle. Enjoy an unlimited number of hints and checks in case you get stuck. Use the calculator tool to help with multiplication and division against large numbers. And rest assured that all puzzle games are automatically saved and restored letting you stop and restart games with ease.
Track your best and average solve times over history with our stats tracker.
Calcudoku, a popular Killer Sudoku variant, was originally invented in 2004 by Japanese math teacher Tetsuya Miyamoto. Also known as KenKen® and Mathdoku, Calcudoku brings to you over 15,000 unique puzzle grids!
You can play Calcudoku by Razzle Puzzles on your phone and tablet. Enjoy Calcudoku online or in offline mode!
