Strip poker is a traditional poker variation where players remove clothing when they lose bets. Since it depends only on the basic mechanic of betting in rounds, strip poker can be played with any form of poker; however it is usually based on simple variants with few betting rounds, like five card draw..
Strip poker sometimes starts with all players wearing the same number of articles of clothing, but the rules are flexible. The consistent aspect is the removal of clothing in place of or in addition to the betting of other games. Like other adult party games, activities besides removing clothing and playing cards might be involved. ("Truth or dare" type options are often included.)
