Demons and Thieves Solitaire Game

Plays: 14360
Category: Cards Games
A fantastic crossover of the famous Demon Solitaire and Forty Thieves Solitaire, Demons and Thieves will test your organization ability amidst different arrangements. Your goal in this game is to move all cards to the 8 foundations at the top of the screen, building up by suit and starting with the cards of the same rank as the card dealt to the leftmost foundation, wrapping from K to A if necessary. When the game starts, 1 face-up card will be dealt to the leftmost foundation serving as the starting rank. Under the foundations are 9 tableau piles. Each of the 4 tableau piles on the left side will be dealt 1 face-up card, while each of the 5 tableau piles on the right side will be dealt 8 face-up cards. 13 face-up cards will be dealt to the reserve pile on the left of the tableau piles. The remaining cards will be placed face-down to the stock pile at the top left corner of the screen, and 1 face-up card will be dealt to the discard pile on the right of the stock pile. The 4 tableau piles on the left side are to be built down by alternating colors, while the 5 tableau piles on the right side are to be built down by suit. In both cases, cards should be wrapped from A to K if necessary. You can move a group of cards to another tableau pile if it forms a legal descending sequence in its current tableau pile, for example, a 7 of spades and a 6 of hearts on a tableau pile on the left side can be moved as a group to a tableau pile on the right side, since they form a legal sequence on the left side. This kind of card movements is called "shift". The top cards on the reserve pile and the discard pile can be moved to a tableau pile or a foundation. If you have run out of moves, you can click the stock pile to deal a new card to the discard pile. The stock pile allows 2 redeals. Challenge your skills now and make as many strategic shifts among the tableau piles as possible!

Category: Cards Games
Aces and Kings is a difficult yet intriguing solitaire game using 2 decks of standard playing cards to play. Your goal in the game is to move all cards to the foundations from A to K and from K to A regardless of suits. When the game starts, 8 empty foundations will appear in the middle of the screen. Each of the 2 reserve piles above the foundations will be dealt 13 face-up cards, while each of the 4 tableau piles at the bottom right of the foundations will be dealt 1 face-up card. The remaining cards will be placed face-down to the stock pile at the bottom left of the screen, and 1 face-up card will be dealt to the discard pile on the right of the stock pile. The 4 foundations on the left side are to be built up from A to K regardless of suits, while the 4 foundations on the right are to be built down from K to A regardless of suits. Each of the tableau piles can only hold 1 card. When a tableau pile becomes empty, the top card on the stock pile will be moved face-up to the space. If the stock pile becomes empty, you can move any card to an empty tableau pile. Each time you can move a card on a tableau pile, the top card on a reserve pile or the top card on the discard pile to a foundation. The top card on a foundation can be moved to another foundation according to the building rules of the foundations. When you have run out of moves, you can click the stock pile to deal a new card to the discard pile. But if the stock pile becomes empty and you cannot make any more moves, you lose. Use the cards on the foundations carefully and make strategic moves across are the keys to increase the chance of winning.
