Klondike solitaire is a simple game, but challenging. Cards are dealt onto the playing board in seven stacks, each topped with a face-up card. Leftover cards are dealt either one at a time or three at a time (see below), and can be placed onto one of the seven stacks if there is a valid destination available. Cards must be placed into sequences of descending order, alternating between red and black: so if you are dealt a red 5, and one of the stacks contains a black 6, that would be a valid destination for your 5.
Cards and even whole sequences can also be moved between stacks to build even larger sequences; if moving a card or sequence from one stack to another exposes a face-down card, click on that card to turn it face-up. If you remove the last card from a stack, you can start a new stack in the empty space by moving a King there.
The ultimate goal of the game is to move all of your cards to four piles at the top of the board. Each pile can contain only one suit, and must be built in sequential, ascending order. To start one of these piles, simply place an Ace at the top of the board, then cover it with a 2, then a 3, and so on. Once all cards have been moved to these piles, you win!
In this variant, clicking on the card deck will deal one card face-up. You may place this card, if there is a valid destination in one of the stacks or the top four piles, or click on the deck again to deal another card.
Klondike Deal 3
This is the classic version of Klondike: clicking on the deck will deal three face-up cards. You can move only the top one of these three cards; however, if you find a valid place for the top card, the next card down becomes accessible, and so on. Clicking the deck again will deal the next three cards.
