Mathdoku+

The only KenKen (CalcuDoku) puzzle with leaderboards.

Based on the same rules as the hit KenKen(tm) game, as printed in the New York Times and The Times (uk).

Related to Sudoko, but with a mathematical twist - use the arithmetic challenges in each cage to help solve the puzzle.

** Why does this app looks so similar to MathDoku? **

This app is based on the Mathdoku App which was originally created by Ben Buxton and several other contributors. I joined the project of Ben in January 2013. I was the main (and as good as the only) developer for versions 1.96 (released in May 2013) and 2.0 (released in September 2013).

After release of version 2.0 I decided to leave the project of Ben and started development of this app based on a copy of version 2.0.0 of Mathdoku. As a result I am no longer restricted to certain boundaries which were imposed by Ben and I now have full freedom to develop the app the way I want it to be. The users of this app will decide if this was a good decision or not.
