How are my stats and progress saved?
Your progress is saved automatically from the first tile you match. The only question is whether you want it tied to one device or synced across all of them.
Guest saving
Play as a guest and your win counts, best times, and current board are stored right in your browser, with nothing to set up. Close the tab and come back later and your stats are still there. The trade-off is that this data lives on that one device, so clearing your browser data erases guest stats.
Syncing with an account
A free account does two things: it syncs your stats across every device you sign in on, and it keeps a permanent name on the leaderboard and daily boards. If you play on both a laptop and a phone, that is the reason to make one, a win recorded on one shows up on the other.
Privacy and portability
Guest stats never leave your browser, and your data stays yours. Because everything runs in the browser, your progress even persists offline until you reconnect. Signing in is purely for convenience, never a requirement to play, as do I need an account explains.

Do I need an account to play?
No. Everything is playable as a guest, and your stats save in your browser automatically. A free account is optional: it syncs your records across devices and keeps a permanent name on the leaderboard, but you never need one to play a single tile.
Can you play Mahjong Solitaire offline?
Yes, mostly. Because Mahjong.now is a progressive web app, single-player layouts keep working offline once the page has loaded, and your stats save on your device. Only features that need live data, like multiplayer racing and the shared leaderboard, require a connection.
Can I play Mahjong on mobile?
Yes. Every layout is built for touch, so you tap a free tile and then tap its match on phones and tablets. There is no app to download, it runs right in your mobile browser, and you can add it to your home screen to play like an app.
How is Mahjong Solitaire scored?
Most Mahjong Solitaire scoring is based on how fast you clear the board, so a quicker finish ranks higher. Some modes also count how many tiles you remove and subtract points for using hints, undos, or shuffles, which rewards clean, unassisted play.
