Although I like this game, I occasionally come across words that are not English, yet English words are often excluded from the possible word list. Just now, I input the word example several times to get the message, not in the word list. Frustrated, I finally gave up the game, only to see example as the longest word. I think there is a little glitch in the system that needs to be worked out.
