Clear the Board is the pinnacle of strategy for String Theory: a Word Game. Using the letters in the deck, you goal is to clear all the letters from the board as fast as you can. You get scored the same as in Classic and Stacked, and ultimately you will want to get the highest score you can to push you up the leader boards. I usually settle for just clearing the board with a score, since you lose 50 points for each and every pass of the string.
Hint: Play 10 more games in any mode to unlock the Clear the Board mode.
