About Solitaire
Solitaire is the card game you've almost certainly played before, here in its standard browser form. Sort cards into descending order and alternating colors, building up the foundation piles until the deck is cleared. No twists, just the classic rules.
How to play
Drag cards between columns and up to the foundation piles to sort them by suit.
Rules of Solitaire
- This is Klondike, the solitaire that shipped with Windows and the one most people mean by the word.
- Seven columns are dealt, the first with one card and the seventh with seven. Only the last card in each column starts face up. The remaining cards form the stock.
- In the columns you build downward in alternating colours, so a red nine goes on a black ten.
- The four foundations build upward by suit from ace to king. Getting all fifty-two cards there wins.
- Turning over a face-down card is progress; a move that does not eventually turn one over usually is not.
- Only a king may be placed into an empty column.
- When the columns stall, draw from the stock. Unlike FreeCell, not every Klondike deal can be won.
Controls
- Drag a card onto another to move it
- Tap the deck to turn the next card
What makes it worth playing
- Standard Klondike solitaire
- Build the four foundations from ace to king
- A timer and a move counter if you want to race yourself
- Cards read clearly at phone size

Tips from playing it
- Empty a column early. A free column is the most useful thing on the board.
- Do not send a card to the foundation if a lower card of the other colour still needs it.
- Turn the deck before you run out of obvious moves, so you know what is coming.
Why this game is here, and what we changed
Chosen because it is genuinely good and its licence (MIT) allows us to host and modify it, which we verified in the project's own files. We host it on our own servers, so it loads straight into the game with no third-party ad code and no pre-roll video. It arrived using a gameplay screenshot as its icon, which looks poor at tile size, so we drew it a proper one. We played it through on a real phone-sized screen on 2026-08-26 before publishing this page, and the screenshots above are from that session rather than from the original project.
More on how we pick and fix these: what we changed in the open-source games and how we test a game.
