Mario, Luigi and all their friends are now part of a special UNO card game! It's the ever-popular UNO, but this version adds a special Mario Block card that makes a character invincible! After another player has played a "Draw 2" card or a "Draw 4" card, the penalty may be blocked using the Block card and thrown back at the other player, making him/her draw 2 or 4 cards! The first player to discard all cards gets the points. The first player or team with 500 points wins. Very important: If you only have one card left in your hand, you have to shout "UNO"!
