Enjoy Calcudoku, a free puzzle game that tests your math and logic! If you like Sudoku puzzles, you will love Calcudoku!
About Calcudoku math puzzles:
Every Calcudoku has a single solution that can be reached logically. Like 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 free math 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 Sudoku variant, was originally invented in 2004 by Japanese math teacher Tetsuya Miyamoto.

Ratings and Reviews
Easy to use. Fun to do. It is almost there. My suggested enhancements are to allow user to select difficulty. One puzzle could have addition, subtraction, multiplication, and division or any combination of equations. When using Notes allow users to decide if they want the Notes to automatically update or not. Allow users to select more than one box to simultaneously add the same notes.
Can’t Listen to Music
It’s a good app for being free. Add banner on the bottom is all I’ve had to deal with.
But I cannot listen to music from other apps while playing, despite there not being any sounds from this app.
Also noticed that this app doesn’t appear in my settings...? Not quite sure why, as all my other apps do.
Needs just a bit more
I like this, but it has two flaws: no undo button (for when I accidentally touch something and change a cell I didn’t mean to and then cannot remember what was there) AND it doesn’t reorient the screen. If I am using my charge cable, I cannot use this app.
