Learn who operates tsumo, how the Mahjong rules and editorial content are produced, and how to contact the publisher.
tsumo is an independent Mahjong learning and play service operated under the tsumo name. For support, account, privacy, copyright, accessibility, editorial, or legal-notice questions, contact support@tsumo.io.
The site exists to help players learn Mahjong through playable browser games, rule-specific tutorials, daily decision puzzles, local club discovery, and original guide or editorial content.
Rules guides, glossary entries, FAQs, and beginner articles are written by the tsumo Editorial Team and reviewed against the live app rule flows, tutorial behavior, and in-app decision surfaces before publication.
When a guide covers a ruleset with regional or house-rule variation, the page explains the baseline implemented by the app rather than claiming to represent every local table. The goal is practical clarity for players using tsumo and for readers comparing Mahjong variants.
Blog posts and editorial pages are separate from gameplay, account, legal, and support surfaces. They are published to add original context around Mahjong culture, learning paths, online play, clubs, and table technology.
We update public content when the app behavior changes, a rules explanation becomes unclear, or a user reports a correction that can be verified. Important legal and privacy pages carry their own versioning and update process.
If you spot a rules issue, broken link, accessibility problem, club-listing mistake, or editorial correction, send the page URL, the issue, and any supporting context through Contact Us.
