Add two distinguishable Jokers to the regular deck, one being designated High, the other Low. These Jokers are considered wild, and can be played virtually at any time on any trick. Either joker can be played as being of higher rank than the Ace of any suit, or lower than the 2, at the player's discretion. This adds a greater element of chance, especially in instances where you might be bidding on an Ace of a suit and someone else will play their Joker to be higher, or when you are trying to avoid a trick by leading the 2, and someone plays their Joker "under" it, rather than playing a higher card.
There are some stipulations to the use of Jokers:
Also, on the rare occasion that a Joker is turned over to indicate trump, there is considered to be No Trump, except for the other Joker. With than in mind, the other Joker is NOT required to be trump, but it is the only card that CAN be trump. Again, the Jokers are wild cards, and can be played at any time on any trick, with only rare exceptions.
