This card caused so much chaos. Here are more #Uno #HouseRules for your consideration:

1. Swap card allowed - swap hands with another player

2. Stacking action cards is allowed

3. Play out of turn - if you have an exact match, you can play out of turn provided that you play before the player in turn; this will skip all players ahead of you

4. Red Zero card = Draw 10, then every player must shift their hand to the next player

5. Show your hand - ask any player to show you their hand
