I wrote a Sudoku game using GtkD and maybe I can get some feedback from you, especially about my Cairo implementation. I am pretty sure that I don't use it to get the most performance out of it.
The grid highlighting takes too much cycles for my opinion. I have ideas to minimize the workload on this but since I am a Cairo newbie I am not sure on how to implement it.

You can get it from http://homepage.uibk.ac.at/~csae6624/SuDoku.html

Thanks in advance.

Looks good, although i don't know if the cairo implementation could be better.
