Diabolo is a card game in which the cards, most showing a single letter (along with a few wild cards that may be used as any letter), are dealt one at a time, face-up, onto the table. The first player to correctly shout out a word formed from the letters represented on the cards collects the cards used to form the word. If an incorrect guess is made, all other players take one card from the table (or from the draw deck if there are not enough cards showing). Play ends when the draw deck is exhausted and no more words can be formed. The player with the most cards at the end is the winner. - BoardGameGeek
