SKIP-BO is a popular card game. In 1967, Ms. Hazel Bowman of Brownfield, Texas began producing a boxed edition of the game under the name Skip-bo. International Games, Inc. purchased the game in 1980. The company was subsequently bought by Mattel. It is a commercial version of the card-game "Spite and Malice".
The deck consists of 162 cards, twelve each of the numbers 1 through 12 and eighteen "SKIP-BO" wild cards which may be played as any number. Alternatively, the 162 cards could be three regular decks of playing cards, including the jokers, with ace to queen corresponding to 1 to 12 and the kings and jokers corresponding to the SKIP-BO cards. Before 1980, the commercial game consisted of three decks of regular playing cards with six SKIP-BO cards replacing the standard two jokers in each deck.
Two to six people can play at a time, in pairs or individually. The object of the game is to be the first player to play out his entire stock pile. Players are dealt a 30 card stock pile, with only the uppermost card visible, and a hand of 5 cards, and the remaining cards are placed face down to create a common draw pile. The shared play area allows up to 4 build piles, which must be started using either a "1" card or a Skip-Bo, and each player also has up to 4 personal discard piles. Each turn the active player draws until he has 5 cards in hand, and plays on the build piles. He must play either the next card in sequential order or a wild Skip-Bo card, using either cards in hand, the top card of his stock pile, or the top card of any of his 4 discard piles. If the player can play all 5 cards from hand, he draws 5 more and continues playing. When no more plays are available, the player discards one card to either an empty discard pile or on top of an existing one and play passes to the next player. When a build pile reaches 12, it is removed from the board and that space becomes empty for another pile to be started; play continues until one player has played his final stock card.
