In normal balatro, Jokers like Jolly Joker (+8 mult if hand contains a pair). in this version, it only activates if hand is a pair, not if it contains a pair.
When you sort by Suit, the next round it will sort by Rank while the button says Suit; you need to toggle it twice to sort by Suit.
Also, you start with $0 instead of $4, which makes it harder.
