Not all the Spider Solitaire layouts are winning, and this adds to this game an unpredictable effect. However, the use of certain tricks will help increase the percentage of games with a positive ending.
Spider Solitaire is played with two decks of 52 cards. The game row consists of 10 stacks of cards: 4 by 6 cards and 6 by 5 cards. The top one in each column is open. The first 4 columns of cards have 5 cards that are face down with the sixth card at the bottom dealt face up. The last 6 columns of cards have 4 cards dealt face down, with the fifth and final card on these columns dealt face up. The rest of the cards remain in the deck to be used later.
A player can move an open card of any column of the row to others to the next highest card regardless of its suit. Queen is placed on King, Jack is placed on Queen and so on. You can’t put any card on Ace. It moves to 2. When an open card is removed from the pile, the next card that is closed is automatically turned over face up.
You can also move any group of cards in perfect descending order of the same suit arranged in order as one card. You can move all of them or only a part of the sequence at once. The top card of any pile or the assembled sequence on the vacant cell of the game row can also be moved.
There is a stack - 5 additional groups of cards of 10. All of them are face up. When it is impossible to make any move in the row, a mouse click on the reserve automatically distributes one of the card groups to 10 stacks of the game row.
