SuDoku was built for developing and testing reasoning power of human beings and not of computers... Then why use solvers... Try each puzzle by yourself...

However if you are new to SuDoku, or get stuck when solving Tough SuDoku Puzzles or want to try SuDoku varients as the Jigsaw SuDoku then you should refer to helper or Tutor..

One such SuDoku Tutor developed by me, gives you step by step solving process and logic involved behind each step... and Supports Classic SuDoku and Jigsaw SuDoku..

The software can be downloaded from http://groups.yahoo.com/group/sudoku-tutor/

This will require you to subscribe the said group which is a announcement-onlu list where only new releases are posted for members... no spam...

Any suggesstion for improvement of the software please mail me
