There isn't actually a set number of rounds, I think it mostly depends on how long the rounds take. (I think there's about 15 minutes playing time for the first round.) I haven't rewatched an episode to keep track, but my guess would be it's about four five-letter words and four six-letter words. After that, there's always one seven-letter word (in which both teams take turns making guesses).
