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.

It is exceptionally well designed and if you ever try a similar puzzle app, you will you will throw up your hands in frustration. It is the gold bar for other apps of its kind.
Love the design. The only issue is the number selection and entering. It’s a bit confusing. I wish it followed the same format as your sudokus.

- Currently, this is the only way to skip puzzles that for some reason you don’t want to solve. They get pushed back towards the end of the list of available puzzles so they will be offered again eventually.

- You can select a single cell and then assign a number to it. If you select more than one cell, you can enter candidates for all of them at the same time. For more information on the controls, see “How to Play” in the main overflow menu.
- Markus Wiederkehr
- You can use the undo key to to correct errors, this will restore any candidates that were automatically removed.
Nice design, but serious defects.. here are only some: 1- you can not easily leave the game 2- it deletes my own pencil marks 3- it forces four arithmetic operations on me in each and every game..!! 4- zero is included as a candidate digit in 50% of the games. You can skip such games, but they are offered back to you each time you start a new game

- This app does not aim to be an exact KenKen clone. In this app division for more than 2 cells is defined as the largest number divided by all other numbers in the cage. So 3/ could be 6/2/1, for example.
Beautiful, easy to use interface. The different cage colors and the bold fonts make it easy to read. The button layout and special features like multiple cell selection contribute to ease of use and make this a very elegant app.
- Markus Wiederkehr
- Thanks for the feedback! Stats might be added in a later update. What’s wrong with the calculator? I don’t understand your last point. When you enter a value in one cell and then select a different cell you should not be in pencil mode!
Another fantastic puzzle problem solver. Give 15 minutes without adverts, a great way to try before you buy. More programmers should take this on board.
