Having beat this game (got to 2048) on the original site the trick to beating this game is to keep the high squares all in one corner, so basically just press left and down as much as you can because then you'll start to get large values in the bottom left, and small ones towards the top right. Just knowing this can easily get you to 5k plus scores after a few tries, you'll learn some other small tricks as you play.
start every word with E,T,A,I,N,O,S,H,R,D,L,U,C,M doing that will most of the time show you what word it is before you finish since those are the most common letters. (in order)
Great game, only thing i disliked was those damn ghost guy which are invincible till they get practically right next to your gems. Plus the boss ones actually get to your gems.
