UNO Wild Jackpot is a spin on traditional UNO that incorporates a slot machine-style device and re-writable custom rules cards. Before the game begins, players come up with their own unique custom rules and write them on the dry erase custom rules cards. These are shuffled and inserted into the back of the slot machine. During the game, which plays exactly like standard UNO, you can play a special Jackpot card to pull the lever on the slot machine. This spins a random result on the center wheel, such as dispensing one of the custom rules to a player at the table who must then follow that rule.
