I guess you should have opened with "salet", gets that "a" and "e" in place right away, but as they say MIT researchers can lead a horse to an opening word but they can't make him play optimally
I didn't read it wrong. They wrote it wrong. You can't have "average number of guesses" of 6.4. Because the game stops at 6 guesses. What are they even doing? Assigning a 7 to a loss? It's complete nonsense and whoever wrote that shouldn't be allowed around numbers.
