What Mahjong Hub is

Mahjong Hub is a free website for learning and practising mahjong. It offers games against AI opponents, lessons, guides and tools. Four-player tables are you against computer opponents, not other people.

Not a gambling site

There is no real-money betting anywhere on Mahjong Hub. There is no gambling currency you can buy, and there are no cash prizes.

Points are only used inside the site: to track progress and achievements and to unlock in-game items and cosmetic looks. Points cannot be exchanged for money, cannot be transferred to another person or account, and have no cash value.

Accounts are optional

You can play without signing in. Signing in is only used to save your progress and achievements and to restore them on another device. You are responsible for keeping access to the sign-in method you use.

Purchases

Mahjong Hub may sell digital products, such as study materials. Creem is the Merchant of Record for these orders: Creem sells the product to you and handles payment, sales tax or VAT, invoices and refunds. Mahjong Hub is the provider of the product and its content.

The price and what is included are shown on the product page at the time you buy. Refunds follow our Refund Policy.

Intellectual property

The articles, lessons, tile artwork, game engine and code, site design, and the Mahjong Hub name and logo belong to Mahjong Hub or the people who licensed them to us. Using the site or buying a product does not transfer any of these rights to you.

You may use the site for your own personal, non-commercial learning. You may share links to any page and quote short passages, as long as you name Mahjong Hub and link back to the page.

You may not copy or republish the site or large parts of it, and you may not use our content to train commercial AI models. You may not use our name or logo in a way that suggests we endorse you.

Digital products you buy come with a personal licence for you alone. You may download them and print them for your own use. You may not resell, share or publish the files, or hand them on to others. We keep ownership of the content.

The rules of mahjong belong to no one. Names and trademarks of other organisations, such as the National Mah Jongg League, belong to their owners; we are not affiliated with them. Our American Mahjong practice hands are our own and are not the official card of any league.

If you want to use our content in another way, or you believe something on the site infringes your rights, email [email protected] with the page address and the details. We will look into it and remove material where that is right.

Acceptable use

Do not scrape or crawl the site in a way that puts load on our service. Do not reverse engineer the site or its games in order to redistribute them commercially. Do not use the site for anything illegal.

We may limit or close access for accounts that break these rules.

No guarantees

The site and its content are provided as they are. We try to explain rules accurately, but mahjong rules vary by region and club; for official play, the official rules of your region or club apply.

We are not responsible for indirect losses that come from using the site, to the extent the law allows.
