UNO Stack Pack – Pass the Penalty On 📚🃏

Stacking in UNO? With this pack, yes. The UNO Add-On Pack: Stack Pack from Mattel adds 16 special cards to a classic UNO deck – for players aged 7 and up.

Every card in the Stack Pack works like a draw card that can be stacked, so the next player has to draw more and more. Stack 1 makes the next player draw one card and lose their turn, and Stack 2 makes them draw two. You may play a Stack card on a card of the same colour, in response to a matching Draw 2 or Wild Draw 4, or on top of another Stack card – and the penalty grows and passes on to the next player. Wild Stack 3 is wild, so you can play it on any card, choose the colour and add three cards to the penalty. The dreaded Wild Stack Number works the same way, but nobody knows the size of the penalty in advance: flip cards from the draw pile until a number card appears, and that number decides how many cards are added. The usual UNO rules still apply. Every card carries symbols that help players with colour blindness, and add-on symbols in the background make it easy to sort the pack out again.
