KenSquared: KenKen for Android with Intelligent Puzzle Generation

Download KenSquared ($0.99) from Google Play

KenSquared is a puzzle game based on the popular game KenKen™ and follows the same gameplay rules.

Similar in gameplay to the popular game Sudoku, KenKen involves strategic placement of numbers in a square. The unique aspect of KenKen is the constraints on placing numbers. The game board is divided into regions of squares called cages. For each cage, a number and a mathematical operator are shown and the numbers that you place in that square must, with the given operator, yield the number in the cage. Like Sudoku, the board must be a Latin Square, meaning a number must appear only once in a given row or column. However, a number may be present more than once inside a given cage.

CS undergrad Anthony Sottile developed this app in 2012 after being introduced to KenKen by a friend. He noted that KenKen.com had only a very limited set of puzzles that updated infrequently, and decided to write his own version of the game that would generate as many puzzles as a player wanted. More information can be found on Anthony's website.
