Double Klondike Solitaire — Free Online, Two Decks

Quick Start: Play in 30 Seconds

1. Goal: Move all 104 cards to the eight foundations, building each suit from Ace to King. Two foundations per suit means each suit gets completed twice.
2. Tableau moves: Build columns down by alternating colors. A black 9 goes on a red 10. Multi-card moves are allowed when the sequence is already valid.
3. Empty columns: Only Kings (or valid King-led sequences) can fill them.
4. Stock: Click the deck (top-left) to flip cards to the waste. Cycle as many times as you need — there's no redeal limit.
5. Foundations: Move Aces up immediately. Build each foundation by suit, Ace to King. Either Ace of spades can start either spades foundation.

Double Klondike vs Klondike: Side by Side

If you've played Klondike, you already know Double Klondike's rules. The differences are all structural.

The extra two columns and the larger stock are why Double Klondike feels more forgiving than its card count suggests. There's more room to build alternating-color sequences before they have to break, and the longer stock cycle gives you more chances to reach a buried Ace or low card.

Draw 1 vs Draw 3

Both modes use the same deals. The difference is access to the stock pile.

The win-rate gap comes from access, not difficulty: the same deals are theoretically winnable in either mode. In Draw 3, useful cards land in the middle of a triplet and stay buried until you cycle the stock again. Pick the mode in the new-game menu.

What's the Best Double Klondike Strategy?

Four tactical shifts from single-deck Klondike. The classic Klondike rules (flip face-down cards first, send Aces up early, only empty a column when a King is ready) still apply — these are the additions.

Don't rush both copies of a card to the foundation

Two decks means two of every card. A 4 of spades sent up doesn't lock you out of covering a 5 of spades — there's another 4 still in play. This is the single biggest tactical difference from regular Klondike: the "don't send middle ranks up too early" rule is much weaker here. You can afford to clear the tableau more aggressively, but keep one copy of each mid-rank card in reserve when you can.

Plan multi-card moves before they're forced

With nine columns and longer sequences, you'll often have a six- or seven-card run to relocate. These moves are legal whenever the sequence is already valid (alternating colors, descending). Spot them early and keep an exit column in mind so you're not stuck when the move becomes urgent.

Build longer sequences when you can

With two decks, sequences of ten or more cards are common. They feel slow to assemble but they pay off — a long alternating-color block lets you re-arrange the board with a single move when the right King opens up.

Build foundations evenly

Eight foundations, two per suit. Letting one suit get five ranks ahead of another is rarely worth it. Even progress keeps mid-rank cards available in the tableau and avoids dead-ending the suit that fell behind.

How Often Can You Win?

Single-deck Klondike has a well-known solvability result — about 82% of deals are theoretically winnable, per Yan, Diaconis, Rusmevichientong and Van Roy (2005). Double Klondike has no equivalent peer-reviewed study. The numbers below are practical-play estimates from casual data, not theoretical proofs.

• Draw 1, skilled play: ~30–40% of games won.
• Draw 1, average player: 20–30%.
• Draw 3, skilled play: ~10–15%.
• Draw 3, average player: 5–10%.

The "easier than Klondike because there are more cards" intuition turns out to be roughly correct in practice: the extra columns and unlimited redeals compensate for the larger deck. Some sources claim Double Klondike is theoretically more winnable than single-deck Klondike because there are two of every card — that's plausible but not proven. Treat any specific solvability percentage you see online with the same skepticism you'd treat a single-deck "20% unwinnable" claim.

Related Two-Deck and Klondike-Family Games

Double Klondike sits in a small family of two-deck patience games and a larger family of Klondike-style single-deck games. Worth knowing:

• Klondike Solitaire — the single-deck original. Seven columns, four foundations, the same Draw 1 / Draw 3 split. Shorter games (5–15 min) and a published 82% theoretical solvability.
• Spider Solitaire — also two decks, but a different game. Build down regardless of color, clear by completing King-to-Ace runs in a single suit. Comes in 1-suit, 2-suit, and 4-suit difficulty.
• Yukon — single-deck Klondike with no stock pile. All 52 cards are dealt face-up across the columns; you can move any face-up card with everything beneath it as a single group.
• Forty Thieves — two-deck patience with stricter movement rules: only one card moves at a time and tableau builds down by suit, not by color. A harder challenge with two decks.
• FreeCell — single deck, every card face-up, four "free cells" instead of a stock pile. Almost every deal is winnable. Worth playing if you want to feel skilled rather than lucky.
