UNO - Mario is a collaboration of classic UNO and Mario, where the game is played with classic rules, Pokémon Mario cards and special rules.
Classic rules:
The goal of the game is to get rid of all the cards in your hand as quickly as possible.
Players are dealt 7 cards each, and the rest remain in the deck.
Initially, one card is turned from the deck, starting the game. Players must play a card from their hand that matches the last played card in color, number, or symbol.
If a player does not have such a card in hand, they draw a card from the deck. If the new card does not match the last played card in color, number or symbol, then the turn passes to another player.
When a player has only one card in hand, they must say "UNO". Otherwise, if other players notice, they draw two additional cards from the deck.
Special rules:
Super Mushroom - The player draws 2 cards and the next player skips their turn.
Fire Flower - Removes one card from an opponent's hand.
Star Power - Allows the player to change the current color.
Invincible Mario Card - Protects the player from +2 and +4 cards, by using the invincible Mario card the player no longer draws cards.
