Highest spade in the deck is the Big Joker: . Second highest spade is the Little Joker: . Next is the Ace of Spades, King of Spades, Queen of Spades, etc... The Two of Diamond and Two of Spades are not wild cards. There are some Games without those 2 special joker cards in which the Ace of Spades is the highest card in the pack.

In addition to the 52 standard deck, there are two special cards Big Joker (Red) and Little Joker (Black). These two cards are played as Spades and are higher than the Ace of spades. So the order of the cards are Big Joker, Little Joker, Ace Spades, King Spades, etc... So in your bidding and playing, you have to account for two extra spades that you aren't used to.

In the friends games and money games we do not have the version with the two Jokers. So don't get used to them too much. Just practice a little here and once you understand the concept keep practicing with real players.
