SolitaireA Game That Remembers Where You Stopped
The most requested feature on the site was also the least glamorous: stop losing my game when I close the tab.
What changed
Every game on the site now writes its state as you play. Close the tab, lock your phone, get interrupted for a day — when you come back to the same game, the board is exactly as you left it.
Restored with it: the position of every card including the face-down ones, your elapsed time, your score, your move count, and your entire undo history. That last one is the detail we cared most about. A resumed game where you cannot undo the move you made before lunch is not really the same game.
Lifetime statistics — games played, games won, best time and best score per variant — are kept separately and survive as long as your browser data does.
How it works
The engine already had a complete snapshot mechanism, because that is how undo works: each move captures the full state of the board so it can be restored later. Saving a session is the same operation with a different destination — the snapshot goes into your browser's local storage instead of onto the undo stack.
Because it reuses the undo machinery, the feature landed for all ten solitaire games at once rather than needing per-game work. That is the payoff of the shared-engine approach we wrote about in Ten Games, One Engine.
Where your data lives
In your browser, and nowhere else. There is no account, no server-side profile and no synchronisation. The saved hand never leaves the device it was played on, because there is nothing on our side to send it to.
The trade-off is honest and worth stating plainly: a game started on your phone will not appear on your laptop, and clearing your browsing data clears your saves and your statistics along with it.
What it does not do
One saved hand per game, not a library — starting a new game of Klondike replaces the Klondike hand you had stored, though the other nine games are untouched. Private or incognito windows discard everything when the window closes, which is what they are for. And a browser set to block site data will simply carry on as before, with no save and no error.
If you want a clean slate, the new game button is the whole mechanism. Nothing to opt out of, nothing to delete.
Frequently asked questions
Do I need an account to save my solitaire game?
No. Saving happens automatically in your own browser. There is no sign-up, no login and nothing to remember.
Will my game still be there on a different device?
No. Saves are stored in the browser you played in, so a game started on your phone will not appear on your laptop.
How do I clear a saved game?
Start a new game, or clear your browser data for this site. Both remove the stored hand.

Why We Still Play Alone
No opponent, no lobby, no season pass. Every trend in games for thirty years has pointed away from solitaire, and it has not moved an inch.
Four-Suit Spider Is Winnable
Ten columns, two decks, four suits and a stock that punishes you for dealing too early. It is the hardest solitaire most people ever try — and it rewards a plan.
