I love this game show, it's totally addictive. Lingo is basically word bingo with two teams. 5 chances to correctly guess a 5-letter word. If the word doesn't exist or it's mispelled, the other team gets a bonus letter (unless there's already 4 showing) and a chance to guess. It's similar to Master Mind in that you get hints if there are letters that are in that word and not necessarily in the right place. After correctly guessing the word, you have your Lingo "card" with 10 free spaces filled in at random, and you pull out numbered balls and try to get 5 in a row on your card. Guessing a word gives you points and achieving a lingo gives you double points.
This is a fun easy game, and it's incredible how dumb some people are when all the letters are there and scrambled in front of you and they still can't figure it out! There have been some good players though. I really enjoy watching this show, it's something I can do, and hope to go on someday.
