Strip poker is a party game and a variation of the traditional poker where players remove clothing when they lose a round.
Generally, each game starts with players wearing the same number of articles of clothing, though that is not necessary. In place of money and betting, the players who lose a round would remove an article of clothing. There are different rules as to what happens when a player has removed all of his (or her) clothes. Some groups allow the person to put his clothes back on and continue playing, while others allow the person to continue playing without clothes, until all have removed their clothing, and others for the game to stop at that point, with the players either putting clothes back on, or remaining unclothed or semi-clothed for the rest of the evening.
