Play Mathdoku now! As in Sudoku, the goal of each puzzle is to fill a grid with digits so that no digit appears more than once in any row or any column (a Latin square). Grids size is 9×9. Additionally, KenKen grids are divided into heavily outlined groups of cells –– often called “cages” –– and the numbers in the cells of each cage must produce a certain “target” number when combined using a specified mathematical operation (either addition, subtraction, multiplication or division). For example, a linear three-cell cage specifying addition and a target number of 6 in a 4×4 puzzle must be satisfied with the digits 1, 2, and 3. Digits may be repeated within a cage, as long as they are not in the same row or column. No operation is relevant for a single-cell cage: placing the "target" in the cell is the only possibility (thus being a "free space"). The target number and operation appear in the upper left-hand corner of the cage. The objective is to fill the grid in with the digits 1 through 9 such that: Each row contains exactly one of each digit Each column contains exactly one of each digit Each bold-outlined group of cells is a cage containing digits which achieve the specified result using the specified mathematical operation: addition (+), subtraction (−), multiplication (×), and division (÷). Some of the techniques from Sudoku and Killer Sudoku can be used here, but much of the process involves the listing of all the possible options and eliminating the options one by one as other information requires. ## Mathdoku Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/f9/54/92/f95492a7-d065-a620-4ce4-79c9d3214797/Simulator_Screenshot_-_iPhone_16_Pro_Max_-_2025-09-14_at_18.26.33.png/1320x2868.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/79/e6/ee/79e6ee40-5d2c-1994-7f66-1250e5dda744/Simulator_Screenshot_-_iPhone_16_Pro_Max_-_2025-09-14_at_18.26.47.png/1320x2868.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/c2/f0/a6/c2f0a64f-4a03-b3f0-f62c-dcab082bfbb3/Simulator_Screenshot_-_iPhone_16_Pro_Max_-_2025-09-14_at_18.27.35.png/1320x2868.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/0b/09/1a/0b091a84-af2e-3936-11e9-436b4927ac5a/Simulator_Screenshot_-_iPhone_16_Pro_Max_-_2025-09-14_at_18.49.50.png/1320x2868.png) ## Apps Similar to Mathdoku - [Gravity Orange 2](https://apptail.io/app/gravity-orange-2-jdsc/spain) - [Killer Sudoku Puzzle Games](https://apptail.io/app/killer-sudoku-puzzle-games-TVtg/spain) - [Opdoku = Calcudoku + Mathdoku](https://apptail.io/app/opdoku-calcudoku-mathdoku-zdug/spain) - [Slitherlink Puzzles](https://apptail.io/app/slitherlink-puzzles-Ofxg/spain) - [Grid - 3x3](https://apptail.io/app/grid-3x3-zeSi/spain) - [Calcudoku Puzzle](https://apptail.io/app/calcudoku-puzzle-dArk/spain) - [ナンプレ - 脳トレゲーム](https://apptail.io/app/app-bpLl/spain) - [Calcudoku - Griddle Games](https://apptail.io/app/calcudoku-griddle-games-kIdp/spain) - [Letris: Letter Drop Word Game](https://apptail.io/app/letris-letter-drop-word-game-JYbu/spain) - [Drag & Make 10](https://apptail.io/app/drag-make-10-uGUv/spain) ## Mathdoku Available In - [Spain](https://apptail.io/app/mathdoku-daily-challenge-ULGx/spain) - [United States](https://apptail.io/app/mathdoku-daily-challenge-ULGx/united-states) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
