Check the deck
You need 162 cards: 144 numbered 1 to 12, plus 18 Skip-Bo cards. A Skip-Bo card is wild, so it can stand in for any number. If you find any blank cards in the box, pull them out, because they aren't used.
Your goal
The first player to play the last card from their Stock pile wins, and the game stops right there. In a partner game, it stops when both partners' Stock piles are gone. Want a longer match? Play several games and keep a running score. Whoever wins a game takes 5 points per card still sitting in the other players' Stock piles, and 25 more for winning. The first player to reach 500 points or more takes the match.
