Solitaire.

Klondike uses a standard 52-card deck. You deal seven tableau columns with 1 to 7 cards, only the top card face up. You have a stock pile that feeds a waste pile, and four empty foundation slots. Tableau piles build down in alternating color. Foundations build up by suit starting from Ace. The goal is to move all cards to the foundations.

Win by moving every card into the four foundation piles, one per suit, in order from Ace to King. The game is won when all 52 cards sit in the foundations. Speed and efficiency earn you a higher score.

Yes. If you have a valid sequence in a tableau column — descending rank with alternating colors — you can move the whole stack onto a new column, provided the new column's top card continues the sequence.

When the stock is empty, you may turn the waste pile over and reuse it as a new stock when rules allow. In this implementation, the stock refills from the waste once when depleted, giving you access to previously drawn cards.

Empty columns accept any King or sequence starting with a King. They act as powerful staging areas that let you reorganize long stacks and reveal more face-down cards.

This version uses a single-card draw for the most playable balance. One-card draw gives you more control and higher winning odds, while three-card draw increases challenge and strategy depth.

Not every deal is winnable. Skilled players estimate that roughly 20 to 30 percent of Klondike deals are mathematically solvable, depending on draw rules and play style. Use the reset button to try a new shuffle when stuck.

Red and black alternate in every tableau pile. A red Seven can accept a black Six on top, which can accept a red Five, and so on. Diamonds and Hearts are red; Clubs and Spades are black.

No, but moving Aces to foundations early is almost always the best move. Foundations only grow upward, so an Ace at the bottom of a tableau has nowhere to go.

Points are awarded for cards moved to foundations and for revealing face-down tableau cards. Moving cards back out of foundations costs points, so avoid unnecessary reordering once a card is home.

This version does not include an undo button. Plan carefully and use the reset button if the board becomes unsolvable due to poor play.

No. The game tracks time for informational scoring but does not penalize you for thinking. Take your time to evaluate options and build sequences deliberately.

Klondike is the most familiar Solitaire variant, often called just 'Solitaire.' Other variants like Spider, FreeCell, and Pyramid use different layouts and rules. Klondike is defined by seven tableau columns and four single-card foundations.

A deal becomes stuck when no legal moves exist and no cards remain in the stock. This usually means either an unlucky shuffle or an earlier suboptimal move forced a dead end. Simply reset to start a new deal.
