December 3, 2009 in Games (E)

[prMac.com] Greifswald, Germany - rapidrabbit today is pleased to announce, that their latest puzzle game is available at the Apple AppStore. "yukendo" is an addictive Sudoku variant, also known as KenKen(R). With intuitive touch controls, clear graphics and a global highscore list, yukendo takes number crunching to another level. Beginners and Sudoku masters alike can choose from a wide variety of level sizes and difficulties.

Invented by Tetsuya Miyamoto, a japanese math teacher, KenKen(R) has become popular all over the world. "yukendo" takes this formular and adopts it to the iPhone which is all about clean interfaces, intuitive controls and mobile internet. "yukendo" integrates these features into one streamlined puzzle app and sets a new standard for mathematical puzzles with large 9x9 grids that haven't been seen on the iPhone before.

The rules are quite easy to learn, but difficult to master. As in Sudoku the grid has to be filled with numbers - 1 through 4 for a 4x4 grid, 1 through 5 for a 5x5 and so on. Every number may only occur once per row and column. Additionally the player has to solve cells, which contain a target number and a mathematical operation. "yukendo" shares many concepts with Sudoku, but adds variety to a well known gameplay.

The wide variety of level sizes and difficulty levels allow a short game on the bus or a full afternoon filled with number crunching. Whether the player wants a short distraction, a real mathematical challenge or anything in between, "yukendo" has the right puzzle. The built in highscore list motivates the player to come back over and over to see if he can make it better this time. This also allows a comparison with the best players worldwide without any tedious login or authentication process. Integration of Facebook connect offers the possibility to show the latest achievements to all friends at Facebook. No one has to play alone.

Playing "yukendo" is a fun way to train mathematic and logic skills. Every solved grid feels like a real achievement and the adaptive difficulty avoids frustration. Music and sound support the gameplay to make "yukendo" a unique experience.

"yukendo" is free and offers many hours of puzzling fun. For the advanced player there is a pro version which includes a lot of more features.
