How to Play This Two-Deck Patience Game

Quick Answer: Diplomat Solitaire is a two-deck patience game (104 cards) played with eight tableau columns, eight reserve cells, and eight foundation piles. It is essentially the double-deck equivalent of FreeCell. Build foundations from Ace to King by suit (two complete suits per real suit needed). Win rate is approximately 90–95% with skilled play.

Diplomat Solitaire is the logical extension of FreeCell into the double-deck world. If you have mastered FreeCell and want a more complex challenge that still follows familiar open-cell patience principles, Diplomat delivers that experience with 104 cards, eight free cells, and eight foundations to fill. It is one of the most intellectually satisfying two-deck patience games available.

What Is Diplomat Solitaire?

Diplomat Solitaire uses two standard 52-card decks shuffled together (104 cards total). The game structure directly parallels FreeCell: all cards are dealt face-up to eight tableau columns, eight reserve cells sit above for temporary storage, and four suits must be built from Ace to King on eight foundations (two complete sequences per suit).

Definition: In Diplomat Solitaire, "eight foundations" means there are eight foundation piles — two per suit (Hearts, Diamonds, Clubs, Spades). Each of the two Hearts foundations, for example, must be independently built from Ace to King. This requires both Aces of Hearts and all 13 Hearts cards twice to complete both foundations.

The game is catalogued in patience references and is related to [Baker's Dozen Dozen](https://en.wikipedia.org/wiki/Patience_(game) and other two-deck open variants. It is sometimes confused with other two-deck games like Forty Thieves or Sultan Solitaire, but Diplomat is distinctive in its open-cell structure.

Diplomat Solitaire Setup

Cards needed: Two standard 52-card decks shuffled together (104 cards).

Layout:

1. Deal all 104 cards face-up to eight tableau columns
2. Each column receives 13 cards (104 ÷ 8 = 13 cards per column)
3. Eight reserve cells above the tableau — all empty at the start
4. Eight foundation spaces — all empty, waiting for Aces

Result: A completely open tableau with all 104 cards visible, eight empty cells for maneuvering, and eight empty foundation piles to fill.

How to Play Diplomat Solitaire

Objective: Move all 104 cards to eight foundation piles. Each of the eight foundations builds one suit from Ace to King. With two decks, you need two Aces of each suit to start two foundations per suit, and the full 26 cards of each suit (13 × 2) to complete both foundations.

Tableau building:

• Build in alternating-color descending order (same as FreeCell)
• Place any card on a tableau column top if the moved card is one rank lower and opposite color
• Example: 7 of Diamonds (red) goes on 8 of Clubs (black)

Reserve cells:

• Any available card (top of any column) can be placed in an empty cell
• Cells hold one card each
• Cell cards can be played to foundations or tableau when legal

Group movement:

• You may move groups of cards that form a proper alternating-color descending sequence
• The number of cards in a movable group is limited by: (empty cells + 1) × 2^(empty columns)
• With eight cells and potentially multiple empty columns, large group moves become possible

Foundation building:

• Move Aces to foundations immediately
• Continue building each foundation from Ace (low) to King (high), same suit
• With duplicate cards (two 8 of Spades, for example), one goes to one Spades foundation and one goes to the other

Empty columns:

• Cleared columns can hold any available card or group
• Empty columns dramatically increase your group movement capacity

Diplomat Strategy

Track both instances of each card. Unlike single-deck games, Diplomat has two of every card. Keeping mental track of where both instances of critical cards (Aces, low cards) are located is essential.

Prioritize uncovering all Aces first. With eight foundations to seed and only eight Aces available (two per suit), all Aces must reach foundations before meaningful foundation progress is possible. Scan the initial deal for Aces and plan how to uncover any that are buried.

Use cells for suit separation. When two same-rank cards of the same suit are nearby, you may need to temporarily separate them using cells to route each to a different foundation. Plan these routing moves carefully.

Eight cells provide significant power. With eight cells versus FreeCell's four, your theoretical group movement capacity is much larger. Use this freedom to reorganize large sections of the tableau when needed.

Build foundations in parallel. Try to advance all eight foundations at similar rates rather than completing two foundations of one suit first. Unbalanced foundation progress can create situations where needed cards for lagging foundations are buried under newly built sequences.

Treat duplicate cards as resources. Having two 7 of Hearts is actually useful — one can go to each Hearts foundation. But it also means that in the tableau, two 7 of Hearts competing for the same space creates a duplicate problem. Route duplicates to separate columns when possible.

Diplomat vs. FreeCell and Other Two-Deck Games

| Feature | FreeCell | Diplomat | Forty Thieves | |---|---|---|---| | Decks | 1 (52 cards) | 2 (104 cards) | 2 (104 cards) | | Tableau columns | 8 | 8 | 10 | | Reserve cells | 4 | 8 | None | | Building rule | Alternating color | Alternating color | Same suit | | Stock pile | No | No | Yes | | Win rate | ~99% | ~90–95% | ~60–70% |

Diplomat maintains FreeCell's open-cell philosophy at double scale. Forty Thieves, by contrast, uses a stock pile, no free cells, and same-suit building — creating a very different strategic experience with a lower win rate. See our full comparison in FreeCell vs Forty Thieves.

Diplomat's win rate of ~90–95% reflects the power of eight free cells — even with 104 cards to manage, the open information and large reserve make most deals solvable. The rate is slightly lower than single-deck FreeCell because the larger card count creates more complex dependency chains.

Players in the United States who enjoy board games and puzzle games — particularly those in strategic gaming communities in cities like Seattle and Boston — often discover Diplomat as a natural next step after mastering FreeCell.

Frequently Asked Questions

How many decks does Diplomat solitaire use?

Diplomat Solitaire uses two standard 52-card decks shuffled together, totaling 104 playing cards. This double-deck format is what distinguishes it from single-deck FreeCell. Having two of every card creates additional strategic considerations, particularly around routing duplicate cards to their respective foundation piles.

How is Diplomat solitaire different from FreeCell?

Diplomat uses two decks (104 cards) instead of FreeCell's one deck (52 cards). It also has eight reserve cells instead of four, and eight foundation piles instead of four. The core tableau building rule (alternating colors, descending rank) is identical to FreeCell. Diplomat is essentially FreeCell scaled to two decks.

What is the win rate for Diplomat solitaire?

Diplomat Solitaire has an estimated win rate of approximately 90–95% with careful play. The eight reserve cells provide substantial maneuvering space, making most deals solvable even with 104 cards. The win rate is slightly lower than single-deck FreeCell (~99%) due to the increased complexity of managing duplicate cards and longer dependency chains.

How do foundations work in Diplomat solitaire?

Diplomat has eight foundation piles — two per suit (two Hearts foundations, two Diamonds foundations, etc.). Each foundation builds from Ace to King of its suit. With two decks available, both Aces of each suit must be found and played to start the two foundations of that suit. All 26 copies of each suit's cards must eventually be distributed across the two foundations of that suit.

Is Diplomat solitaire hard to learn?

Players familiar with FreeCell can learn Diplomat very quickly — the rules are essentially identical, just doubled. The main adjustment is tracking two instances of each card and managing eight foundations. For players new to open-cell patience games, learning FreeCell first and then transitioning to Diplomat is the recommended path.

💡 Variant Strategy Note (2026)

Each solitaire variation demands unique table space management. In column-heavy formats like Spider or Yukon, prioritize unlocking hidden columns early to act as temporary staging areas.
