Lettra

This is a promotional game not freely available. It was given to customers of UBS (Big Swiss Bank). Players form words with as many letters possible from their hands. Afterwards they fill up their hands with cards from their Stock. The game itself is kind of similar to "Scrabble Cardgame" except in this game you are allowed to exchange letters in existing words. The game ends when a player has used up his stock of 30 cards.
