You'll be decoding six-letter words by writing your guesses for each letter on the touch screen. Imagine the secret word is "winner". You'll need to enter letters at random, and automatic hints will tell you how many letters are correct. Difficulty can increase by reducing the number of guesses you can take per round, and if you don't correctly guess that the word is "winner", then you are a "loser."
It might sound incredibly simple and/or lame, but let's not forget the thousands of people who sit there solving Sudoku puzzles all day. Those guys are the real winners.
