Here are the rules. You can read on and try for yourself
or you can watch a demo game played by the computer
to get a better idea of the gameplay.
Skip98 is a two player game. The game uses 164 cards,
144 cards representing the numbers 0 to 12 and 18 Wild Jokers.
The deck is distributed by first dealing a configurable number
of cards that make up each player's stock pile.
Only the top card is turned face up.
The desktop setup is seen on the following screenshot:

The object of the game is to be the first to use all the cards from his Stock Pile.
Cards are played onto the Building Piles in increasing order, from 1 to 12. Jokers are used as wild cards. Each pile must be started with a "1" or a Joker. When a "12" is played onto a Building pile, the pile is removed and the space can be used to start a new pile.
After the stock cards are dealt, each player plays in turn. A turn starts with a player being dealt enough cards until 5 cards are in his Hand. Then the player has to try to use cards from his Hand or cards previously discarded onto his own Discard Piles so that he can be able to play the top card of his Stock Pile. When this card is played, the next card from the Stock pile is turned face up.
Cards can only be played onto the Building Piles using the next card in sequence or a Joker. Only the top cards from the Discard Piles can be played. The player can continually play until he can't play anymore, at which time he has to discard a card onto one of his Discard piles and his turn is over.
If a player uses up all of the cards from his Hand, he will be dealt another 5 cards to play with.
Well, I hope this is clear enough. If not, run the demo and look at the computer play.
