About Andoku Calcudoku
How to play
The Calcudoku game grid has to be filled in such a way that the specified conditions are met by simple calculations in the four basic arithmetic operations.
As with Sudoku, no number may appear more than once in any row or any column. In addition, there are so-called cages, each of which contains a mathematical operator and a target value. This value corresponds to the result to be achieved by the calculation with the values in the cage.
Every puzzle has a unique solution that can be found without guessing.
Features
• five different grid sizes (from 5x5 to 9x9)
• six levels of difficulty per grid size
• 15,500 unique puzzles in total
• games are automatically saved
• unlimited undo/redo
• a built-in calculator
Origin
Calcudoku was developed by the Japanese teacher Tetsuya Miyamoto for his students to promote the ability of mathematical and logical thinking. The game is also known as MathDoku, Ken-Doku™ and KenKen™.

Good puzzles. Wish there was a paid version because the ads are irritating

Well made, addictive, can play offline, dirt cheap to unlock. What's not to love?
