Think your vocabulary and spelling skills are the tops? Let Word Sandwich disabuse you of that notion. The premise of the game is fiendishly simple: You have to guess the mystery 5 letter word. Aha! But your only hints come via your own guesses. Words that start earlier in the alphabet than the mystery word are floated up, while words lower slide below. Your goal is to whittle down the difference until you can pinpoint the target word.
