How to play Solitaire
This is standard Klondike solitaire. Seven tableau columns are dealt in front of you — the first holds one card, the seventh holds seven, and only the bottom card of each column starts face up. Above them sit four empty foundations, one per suit, and the remaining 24 cards form the stock.
You win by moving all 52 cards onto the foundations, each built up from Ace to King in a single suit. To get there you rearrange the tableau, where columns are built downward in alternating colours — a red seven goes on a black eight, never on a red one.
Tap a card and it goes wherever it fits, trying the foundations first and then the tableau. That single tap is the whole control scheme on a phone. If you want to choose the destination yourself, drag the card instead; legal targets light up in green while you drag. On a keyboard, U undoes, R restarts the current deal, N deals a new one, and Space draws from the stock.
The rules this game actually applies
An empty column only accepts a King. Not a Queen, not any other card — which is why emptying a column is a real decision rather than a free win. A column that still has face-down cards under it is not empty, even though nothing face-up is showing; the game turns the next card up for you the moment the last face-up card leaves.
Whole sequences move together. Because every face-up run in a column is already a valid alternating descending sequence, you can pick up any card in that run and everything below it travels with it. Grabbing a seven with a six and a five under it moves three cards in one move.
The stock turns one card at a time, and it recycles as many times as you like. When the stock runs out, tapping it turns the waste pile back over in the same order and you go around again. There is no redeal limit and no penalty for cycling, which is the single most important rule here: because every card in the stock stays reachable forever, you can never lose by running out of chances.
Cards can come back off a foundation. If you send a card home too early and then need it to hold a lower card, you can pull it back down to the tableau. It costs you 15 points, but it is available.
Every deal is checked before you get it
Klondike deals are not all winnable. Rather than hand you a random shuffle and let you discover after twenty minutes that it was hopeless, this version ships a fixed table of 120 deals that a solver has actually solved, and you are only ever given one of those.
The check is deliberately strict. The solver searches with a budget of 200,000 positions and reports one of three answers: solved, unsolvable, or unknown. Only deals in the first group are shipped — a deal the solver ran out of budget on is thrown away rather than assumed fine. Each accepted solution is then replayed move by move through the game's own rules to confirm it ends on a real win.
That guarantee is about the deal, not about your play. A solvable deal can still be played into a position that can no longer be won, which is what the next section is about.
You can still play a winnable deal into a dead end
This is the part most solitaire games leave you to figure out alone. Sending a card to a foundation is permanent in practice: a nine sitting on the foundation can no longer hold an eight, so a tableau column that needed that nine is now stuck.
In a balance test of forty runs, a player making random legal moves walked into an unwinnable position in 14 of them, typically within the first fifteen seconds. That is not a flaw in the deals — all forty were verified solvable — it is what happens when cards go home without a plan.
So the game tells you. When no move can change the board any more — when drawing only cycles the stock past cards that have nowhere to go — a message appears under the board saying exactly that. Undo is unlimited (up to the last 200 moves), restart puts the same deal back the way it started, and a new deal is one tap away. You are never left wondering whether it is the deal's fault or yours.
Scoring
The score comes only from what you do, never from how long you take. There is no timer, and sitting still scores nothing at all.
Moving a card to a foundation scores 10 points. Turning over a face-down card scores 5. Moving a card from the waste pile into the tableau scores 5. Taking a card back off a foundation costs 15, and completing all four foundations pays a 200-point bonus. The score never drops below zero.
Undo rolls the score and the move counter back together with the board, so an undone move costs you nothing but is counted separately and shown when you finish. Your best score is saved in your browser on the device where you play; there is no account and no ranking.
Three habits that decide most deals
Turn face-down cards over before anything else. Every face-down card is information you do not have, and the columns start with 21 of them. A move that reveals a new card is almost always better than a move that merely tidies two face-up cards, because the tidy move can usually still be made later and the reveal changes what you know.
Do not send cards home just because you can. Aces and twos are always safe — nothing needs them. Beyond that, a card is only safe to send up once both opposite-colour foundations have reached the rank below it, because at that point no tableau card can still need it. Before that, a card on a foundation is a card that stopped working for you.
Have a King ready before you empty a column. An empty column is the most valuable thing on the board and the only place a King can go, but it accepts nothing else. Emptying one with no King available anywhere — not in the tableau, not in the stock — leaves you a hole you cannot fill and cannot use.
Device support
Solitaire works in a desktop browser and on phones and tablets in either orientation. The seven columns are laid out so that even on a 390-pixel-wide phone every card keeps a touch target at least 44 pixels tall, and animations are switched off when your system asks for reduced motion. It is self-contained, with no download, account, or third-party runtime.
