When starting a word game or word puzzle, you’ll most likely be looking to play a 7-letter word. First of all, you want to clear off your entire rack, and second, you want the "Bingo" bonus points to put you leagues ahead of your friends or opponents.
If you’re playing Scrabble, that’ll mean 50 extra points, and if you’re playing Words With Friends, you’ll be getting 35 bonus points. However, finding words with seven letters can be quite a challenge. That’s where seven-letter word lists come into play.
