One I enjoy but haven't played in a while is Balderdash. An unheard of word is read by the moderator (who changes from turn to turn) and players must write a definition for it. The moderator then reads all definitions (including the real one). You can earn points (and presumably spaces on the board) these ways:
- If the definition you wrote is correct (unlikely, but possible)
- If you guess the correct definition.
- If another player chooses your fake definition as the real one.

There's always a player who tries too hard to have his definition sound genuine, and also one who writes the silliest things. Funny thing is, sometimes the actual definition is so absurd that you think it was submitted by the silly guy. Eventually the whole affair becomes a laugh fest and often the moderator has a hard time reading the definitions due to uncontrollable laughter.

Blokus is one I played for the first time last Christmas. One of the kids got it as a gift but as you play it you see that it is challenging for adults, too.
