About Solitaire Online NZ

About solitaire-online.nz

solitaire-online.nz exists for one simple job: to let you open a browser, anywhere in New Zealand, and be playing a proper game of solitaire a second later. On the laptop at home, the tablet on the couch, or your phone on the bus from Takapuna. No app store, no installer, no account and no email address, just the cards.

The site is run by Forty Media. You can reach us at info@solitaire-online.nz.

Built for whatever screen you have

Every game here runs in any modern browser. We have kept the things that matter when you play on different devices:

• Large, clear cards and readable text, with a zoom control to make the board bigger on a small phone or for tired eyes.
• Drag and drop, or tap a card and then where you want it to go, whichever suits your screen.
• Fullscreen mode, a choice of table colours, and sound you can switch off for a quiet room.
• Hint, unlimited Undo, Restart and Auto Play on every game, for everyone.
• Your win count for each game is remembered on the device you play on, and the current game keeps track of your time and moves.

Twelve games to play online

• Klondike Solitaire, turning one card, and Solitaire Turn 3.
• FreeCell and Baker's Solitaire.
• Spider Solitaire, plus two-suit and four-suit Spider.
• Yukon, Alaska and Diplomat.
• Golf and Pyramid, both good for a game that lasts a few minutes.

The full list is on the games page. If you are new to patience, start with Klondike on the home page: it is the game most people already half-know, and every other game here makes more sense once you have played a few rounds of it. If you only have five minutes, Golf is the quickest. If you have a long evening and want a proper puzzle, try FreeCell, where every card is face up and the result is down to you.

Numbers we measured ourselves

We like knowing how a game behaves, so in September 2026 our team rebuilt each of these games in Python, using this site's own rules, and ran simulations over thousands of numbered deals. For some games we used a simple bot that sees only what you see; for others a solver allowed to see every card; for a few, an exhaustive search that gives the exact answer.

Some results surprised us. On this site, Golf lets you play a King on an Ace and an Ace on a King. With that rule our exhaustive search found 92.7% of 10,000 deals winnable; without it, only 44.0%, which matches the 45.1% published by Blake and Gent in the Journal of Artificial Intelligence Research (2026). Turning three cards instead of one in Klondike cut our bot's win rate from 42.3% to 10.6%. Each game page explains its test step by step, including the parts we had to assume and the limits of what the numbers can tell you.

How we write and check the site

We used an AI assistant, Claude, made by Anthropic, to help write and review the simulation code and to draft pages. The AI did not produce any of the figures: every number comes from running the code, and the team checked the results against published research before they went live. Pages are published under the byline Admin on behalf of the solitaire-online.nz team.

• Rules are written the way the games actually play here.
• Statistics come with their method and, where it matters, a range rather than one neat number.
• Outside figures are linked to where they came from.
• Corrections are welcome and get fixed.
