Penguin Solitaire
Penguin Solitaire is a strategic FreeCell-family patience game that you can win nearly every time—now playable free and full-screen on solitairex.io. Invented by British games scholar David Parlett while he was writing The Penguin Book of Patience, the layout features a unique “beak” card, seven “flipper” cells, and a win-rate of about 99.9 %, making it one of the most rewarding solo card puzzles on the web.
Game Overview
- Family & difficulty: Member of the FreeCell group—perfect-information games where every card is dealt face-up; skilful play, not luck, decides the outcome.
- Deck & deal: One 52-card deck is dealt into seven columns of seven cards; the first card dealt becomes the beak and its three mates leap straight to the foundations.
- Foundations: Built up in suit, wrapping King→Ace, starting from the beak’s rank.
- Tableau: Built down in suit, also circular; complete in-suit runs move as a single block, with no free-cell count limit.
- Flipper cells: Seven single-card reserves give flexibility but punish careless parking.
- Empty-column rule: Only a card (or run) one rank below the beak may start a vacant column—mastering this rule is the key to fast clears.
How to Play Penguin Solitaire Online
- Free the beak early. Clearing the leftmost column unlocks the fourth foundation and speeds up the rest of the build.
- Keep flipper cells transient. Always plan how you’ll empty a cell before you fill it; seven slots evaporate fast.
- Create at least one empty column. A vacant pile functions like a super-cell for whole suit sequences that begin one rank below the beak.
- Move full runs whenever possible. Because runs ignore cell limits, sliding a long suit sequence can unblock multiple cards in one stroke.
- Finish foundations aggressively. Unlike Klondike, there’s no penalty for building early—send cards home the moment they’re free.
History & Origins
- Created by David Parlett (b. 1939). Parlett is an award-winning designer (Hare & Tortoise) and historian of card games; Penguin is one of several original solitaires he published in the late 1970s.
- Named for The Penguin Book of Patience—Parlett wrote the rules while compiling that landmark 1980 compendium.
- Solver statistics. A 50-million-deal computer analysis estimates only 1 in 1 667 deals is unwinnable (≈ 99.94 % success), slightly tougher than classic FreeCell yet easier than Eight Off.

Golf Solitaire Mastery: Strategy, Stats & Flow
Deal 7 columns of 5 face‑up cards (35 total). The remaining 17 cards*form the stock; flip the first stock card to start the waste. You may move only exposed tableau cards, and only if the rank is exactly one higher or lower than the waste top. Suits don’t matter. When no move exists, flip a new waste card. Clear all tableau cards to win.
TriPeaks Solitaire Mastery: Strategy & Analytics
Two peaks are dust; one stubborn ridge remains. Your waste shows a 9. The tableau flashes 10‑J‑10‑9‑8 like a heartbeat. You nudge the 10, feel the cadence lock in, and—without overthinking—trace a neat descent that crumbles the last peak. That tiny spark of *flow* is why TriPeaks hooks serious players: rhythm, restraint, and the rush of a run that arrives exactly on time.
Pyramid Solitaire Mastery: Strategy, Stats & Joy
Picture the pyramid down to its last stubborn tier: a Queen pinned beneath a ridge, a lone Ace on the waste, and a King begging to be burned for tempo. Heartbeat, breath, click—then the whole structure yields in a rush. If you’ve hit that razor‑edge finale, you already know Pyramid’s secret: small decisions, made in the right order, change everything.
FreeCell Solitaire Mastery: Strategy & Analytics Guide
I have a 15 years personal, lived experience—picture a scene built from thousands of session logs and notes from serious players: It’s late, and the board looks jammed. You clear a single column, free one cell, and suddenly a 9♣‑8♦‑7♣‑6♦ chain glides into place, untying the knot you stared at for ten minutes. The rush isn’t luck—it’s the quiet pleasure of a plan snapping into focus. When did FreeCell last feel less like “killing time” and more like practicing a craft you can actually master?
