Deal out the rest of the cards to the remaining players. Start flipping the cards over, starting with the bottom left and working in a clockwise motion so you end with the card above the gap. The first card flipped is worth 2 drinks if you have that card you can pass it to someone for 2 drinks.
Once you receive a card you lay it face up in front of you and you can't get rid of it.
The next card is worth 4 drinks then 6 and so on. So you may have 4 drinks for one card you received then the 15th card is the same card you have to drink 30 drinks.
