I just love this game. Letters replace traditional cards, but the play is the same. Clear the board by making words. Details of game play are in the Alt if interested.
If I get stuck ill just try combinations of letters trying to make any word. This has brought words unique and wonderful to my attention, like
STYLITE : A Christian ascetic in ancient times that lived at the top of a tall pillar. Strangely specific. I simply MUST use that in conversations more often.
