Unusual Quartett game that tries to be a teaching aid. The cards have a letter in the corner and it is printed on both side (with different letter to each side). Players collect cards in the same way as usual Quartetts but a set of four can only be claimed if you make a word with the four letters in your set. Some cards have two letter combinations on them and if you use them, you must use both letters in the word and they must be adjacent. For example, if you wanted to make the word 'Glück', you would need a G, an L, a ü and a ck.
