Word games with tactical Tetris-like elements

Hi,

I would like to ask you a question. Are there any word games with tactical Tetris-like elements, in which a player can move his or her letters around to form words or not? I know that SpellStack is a game with these characteristics, but are there more games with identical or similar characteristics or not? Can a player score bonus points for spelling a word correctly and for guessing long and obscure words or not?
Have a nice day,
André
