Hasn't happened in at least a year -- I got a 6 piece, dynamic cut solved in 5 seconds! I'm pretty sure I once got a 2 second puzzle, not many 3s, several 4s, lots of 5s, and scores and scores of 6s. Nowadays, I happy with a 6, so this 5 was a real treat. Hope all is well with this cite's happy puzzlers!
