Stack cards in a pyramid. The top of the pyramid has one card, the 2nd row has 2 cards, 3rd row 3 cards, 4th row 4 cards, 5th row 5 cards. Deal each player 4 or 5 cards face down (five will be harder). Lay your cards out in a row infront of you, once you do this there is no arranging them, they are set like that for the whole game. Everyone looks at their cards once for about 3-4 seconds when the game starts (no shuffling them around). All you have to remember is the cards number and location, not the suit.

You start the game by flipping over the bottom left card of the base of the pyramid (and work your way across the bottom row). Now this is where the B.S. comes into play. Say the card flipped is a 6 and lets say that you have a 6, you get to tell someone to drink. The person can drink if they think you have it or they can call B.S. If they call B.S. then you have to, without looking, flip over your 6 card. If you mess up, you have to drink double. If you were lying, drink double. If you pick the right card they have to drink double for doubting you, if they don’t call B.S. then they just drink one for believing you.

Once this game gets a few rows up people will be afraid to call B.S. because the drinks double. Remember the bottom row is only one drink, 2nd row up=2 drink, 3rd row up=3 drink, and so on. That amount doubles for every B.S. call.

Always good to start out by giving drinks to someone that has never played, even if you don’t have the card. Chances are they won’t call B.S.
