In Scheibenkleister one player tries to describe a word, term or person that the other players then need to guess – well, most of the other players. One or two opponents are trap makers who also know the word to be described; they try to foresee how the explainer will go about describing the word and lay down traps by secretly writing down two "trap" words each. If either the explainer or one of the guessers uses one of these words, the trap maker who wrote the word scores. If anyone says a trap word, all trap words are revealed, and the guessers now have one final guess at the solution. Now a correct guess will score points for the trap makers rather than the explainer. Thus, the explainer's challenge is trying to avoid using "obvious words" – which often results in an explanation that is severely cryptical and not very to the point.
