I'm Michal from Czechia and as you might have guessed I love logical puzzles. Although it took me a while since I've found my way here I have to say this is in my opinion the best site of this genre. Both when you look at the quantity (you can't compete with random generators though of course) and the quality of puzzles. I want to thank all the administrators, puzzle makers, site founders and all the others for such a wonderful time killing machine.
