With a lot of people asking me questions like 'How do you solve this puzzle?', 'Are there any tricks in solving this sudoku?', 'How do players solve so fast?', etc. I have decided to start sharing some solving techniques.

Feel free to comment and give me feedback. If you want some solving techniques of a particular puzzle, you may ask here and I will try to post some tips :-)

Hope you like and benefit from them :-)

Hi Rohan,

First of all, I love your blog--it helps me keep track of some of the puzzle championships I might miss, and it also has some useful solving techniques.

I was writing to ask about some good solving techniques to make use of in Star Battle puzzles. I have never really known how to approach one, and the Hard Star Fillomino on the recent LMI test included some steps that I wasn't aware of. Your techniques on the Puzzles like the Yin-Yang have made it easier to approach puzzles, so maybe knowing some good starting tricks for Star Battle might make it easier to digest.

Thanks for your time; I look forward to your future entries on this blog.
