I'm a Pixie! I've been chosen to be part of a team of volunteers to help promote the fabulous puzzles of Conceptis.
You've probably seen some of their publications, they print books of all sorts of Japanese picture puzzles, Nonogram, Sudoku, Kakuro, Maze puzzles, Logic puzzles, Paint By Number, Link-a-Pix, I could go on as they produce just about every sort of brain using puzzle.
But I bet you didn't know that they have a really great web site at http://www.conceptispuzzles.com/ where there are loads of puzzles all for free. Plus there is a great forum where you can find help and access to even more puzzles. You will never have a spare moment once you've found this site. It's great!
