Description of Calcudoku This blissful puzzle application is a colorful, mobile rendition of the popular Calcudoku game — also known as KenKen or MathDoku. (KenKen is a trademarked name of Nextoy LLC. with which I am not affiliated.)Calcudoku mixes in arithmetic to the familiar Sudoku-type puzzle game. However, you might find that Calcudoku is often more challenging than the generic Sudoku game. You'll notice that there are various angles that you must exploit to arrive at a unique solution.I have personally played Calcudoku many times on the online website before I decided to make this app. It's a great game to practice your logic skills and/or relieve your boredom. Current features: – Special input controls: You can either drag a cell or use the number pad to add a number. – Many puzzles: I will keep adding puzzles as long as people keep wanting them. Currently there are 80 puzzles for every size. That's 480 in total. – Colorful user interface – Categorized by size: You can choose to play out of any board size between 4×4 and 9×9.Upcoming features: – Sounds – Undo button——————Please download the donate version if you enjoy this game.
