Player one is dealt a card. S/he then guesses whether the next card will be higher or lower than the next card.

If wrong, s/he drinks once (because one card was showing).

If correct, s/he guesses again.

After taking at least three cards, the player may choose to continue or pass, BUT ONLY after having taken at least three cards.

If the player pass, the next player starts where the previous left off.

When a player guesses incorrectly, s/he drinks for each card showing.

So, the strategy is to build up a lot of cards and then pass it to the next player.
 

Before play starts, determine by vote if equal cards are a loss or correct guess.
