I just released my 4th book: Pixel Paint by Number Logic Puzzles Winter. I'm happy to finish this book, especially since it completes the four seasons series that I started creating in 2003.
I am really proud of my books. So much hard work went into each one, I feel that it is quite an accomplishment to finish a set of four.
If you are unfamiliar with this type of puzzle (nonogram, griddler, tsunami puzzle, art by number), please visit my website , where I have a "how-to solve" tutorial, free sample puzzle and more info.
