United StatesHow 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.

• six levels of difficulty per grid size
• 15,500 unique puzzles in total

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™.
Been playing for years. I love how the ads are silent by default in this game so I can play it while I fall asleep with calming music on. The ads are so reasonable too. And the game is great. Some more challenging than others. Only thing I wish they had was a dark view so it doesn't hurt my eyes/sleep as much. I play almost every night while winding down to quiet my mind of all the fuss of the day.
I like to see 0- WITH 5 CELLS
To be perfect the hardest levels needed to be a lot harder
This is an excellent game, and by far the best calcudoku game on the app store. However, when compared to some of the other games by this developer, it is extremely lacking. Many features which I expected to be included by default were lacking.
Absolutely the best.
This game is great! Can you possibly add the 'compute candidates' options at least with basic sudoku logic ( without excluding invalid multipliers)? It can get stressful pretty fast to fill a 9x9 table with candidates initially... Thank you!
Nice puzzle app to learn math/puzzle skills if you're younger & to keep skills up for those of us who're older.
