is a card used in trick-taking games
that automatically counts as the highest trump.
If no-trump rounds are allowed, the Benny is often considered to be a solitary trump, in a suit of its own.
Normally, the Benny is represented with a Joker or the two of spades.
The most common use of Benny is in a 25-card euchre variant. It is for this specific game that the Joker was introduced in the 19th century United States.
