UNO Mario Kart plays like classic UNO except each card has a symbol in the bottom corner that represents iconic Mario Kart items (Mushroom, Banana Peel, Green Shell, Lightning, or Bob-omb). The items don’t do anything during regular play, but if you play a Wild Item Box Card you get to flip the top card of the deck into the discard pile and immediately use the item shown on that card. Each item has a different action:
Mushroom: Take another turn.
Banana Peel: The player who went before you has to take two cards.
Green Shell: Any player of your choice must take one card.
Lightning: All other players must take one card, then you take another turn.
Bob-omb: You must draw two cards, then you can pick the color that continues play.
