Each of the 16 cards in the Stack Pack acts like a Draw Card that players can stack to make other players draw more and more cards. Play a Stack 1, Stack 2, or the dreaded Wild Stack Number card, and soon players will be passing out penalties like popcorn. Makes a great gift for UNO fans and card game lovers ages 7 and up.

• A Stack 1 Card makes the next player draw 1 card and lose their turn, a Stack 2 makes the next player draw 2 cards and lose their turn.
• Players may play a Stack card on another Stack card (or other Draw Card) if the color matches, increasing the number of cards the next player must draw.
• A Wild Stack Number card makes the next player draw a random number of cards. Flip the top card of the Draw Pile to find out how many!
• Each card has special graphic symbols to help identify the color of that card, to allow players with ANY form of color blindness to easily play.
• Add-On symbols in the card background let players easily swap out packs to find the mix they like.
