Uno
You need two or more people and a deck of UNO cards, as well as whatever alcohol you desire as shots. The game works best with six people.
Rules
Take a deck of UNO cards, and remove the four blank cards that come with each deck (there is one of each colour) Write “take shot” on each of the blank cards. Add the cards back to the deck and play as you would a normal round of UNO (keeping score is not needed) The “take shot “ cards may be handed out as normal cards and the person on the receiving end takes a shot when receiving one of these cards. The first person out of cards gets to give out one shot. The person who has the most cards at this time must take a shot.
