4 to Fortune is a tournament game mode (accessible from the Tournament Lobby) where you have a limited amount of time to spell as many words as you can for the highest score.
 
4 letters are presented to you in which you must create a 4 letter word in order to score points.
 
The farther you get, the more quickly the timer counts down, so watch out! Because you'll have to find words even quicker for a higher score! Final scores are added to the leaderboard.
