Write words, so they hook into each other; i.e. the last letter in a word should be the start of the next word.
During 30 seconds you write as many words as possible in the category you randomly has pointed at on the subject sheet. Next time you pick a new subject.
The one who first fills his sheet with a long chain of words is the winner.
Could be played as 2 player or as 2 teams (probably not more than 2 players in each).
The game is licensed from "The Michael Kohner Corporation" to the Swedish company Alga, so it exists probably in other countries.
