Mathdoku+

只有啃啃（CalcuDoku）拼图排行榜。

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.
