PRO: unlimited free gameplay

CONS: bug in the system - periodically null solution (literally no word to solve for - really, a bummer to have to start over when you're on a 200+ word streak); doesn't save progress or streak record (if you close & return to the page) even with registered account; lots of repetition in some words; excessive use of slang & city names (while not recognizing legitimate dictionary spellings of other words when attempting to identify letters)
