Thanks for the praise, Liz!

A "donate" link sounds like a great idea (specially as I've recently paid for a new web host and a download.com listing for Nonosweeper so I've made a loss on it so far!) so I've added one at the bottom of the main and best times pages; everyone feel free to use it as often as you like!
Or use this link:
https://www.paypal.com/xclick/business=info%40nonosweeper.comAnother good way to help the site is to tell all your friends about it and get them addicted too - and better still ask anyone you know with a website to link to Nonosweeper.com.
Mind you, I'm grateful to all users just for playing the game and making things more competitive

There aren't any cheats or easter eggs in the game, and I've done my best to stop people cheating/hacking so the best times table reflects the genuine records. I'd be happy to put easter eggs in though, if you want!
I can't say for sure how 1 second on beginner was achieved, but I believe it's possible, even if it requires playing the game thousands of times until the right grid comes up, e.g.:
000000
XXX000
XXXXXX
XXXXXX
XXXXXX
XXXXXX
This can be done in 1 second, I guess.
Anyway, thanks again Liz - I hope to see you on the Genius scoreboard soon!
Oh, I almost forgot - have you tried World of CryptoPics? It has even more "weird squares" than Nonosweeper!
