## About Mahjong Club

The people, rules and care behind the table.

[By Mahjong Club](https://tileleague.com/about.md) Updated 26 October 2026

### A place to learn and play together.

Mahjong Club is published by Orion Designs LLC. The website, the browser game and the planned iPhone and iPad listing, Mahjong Club: Play together, share the Mahjong Club name. The address tileleague.com comes from the product’s earlier name, Tile League. References to the Mahjong app in older guides describe this same product.

The browser game is available now. The iOS app is awaiting publication, and its expected App Store address is retained for launch.

### Be clear about the rules at the table.

Our Taiwanese game follows a versioned implementation of the LRC rules published in December 2024. Guides distinguish that fixed interpretation from other Taiwanese house rules. We preserve worked tiles, assumptions, awarded elements and payments so readers can check an example.

MRS estimates skill separately from table points. Its wider use as a shared standard remains a proposal; this website does not claim independent adoption or endorsement.

### How we prepare and update guides.

Guides credited to Mahjong Club are prepared by the publisher. Product instructions are checked against the actual interface and implementation. Historical articles cite their museum and university sources. A visible update date describes a substantive guide revision, not a new edition of the source rules.

Demonstration players, scores and screenshots are fictional. A publisher’s guide is not an independent product review. We name an external reviewer only after that person has actually reviewed the material.

English, Traditional Chinese, Simplified Chinese and Cantonese editions are maintained as corresponding guides. Rule terms and scoring numbers should agree across editions; tell us when a translation makes a procedure unclear.

### Questions and corrections

For a correction, include the guide address, the rule or step in question and the source or example that helps explain it. Do not send private game records or account credentials.
