About SG Mahjong
Who maintains this free game, why it exists, and how its rules and public guides are checked.
Why SG Mahjong exists
SG Mahjong is a free browser game created to make this Singapore Mahjong ruleset easy to practise alone and easy to share with friends. It combines a playable table with rule references that explain the same legality, scoring, wall flow, and virtual-chip settlement used by the game.
The project does not sell chips, accept wagers, award prizes, or provide real-money gambling. Its purpose is entertainment, learning, and private play.
About the creator
SG Mahjong is created and maintained by its creator, who has chosen not to publish a personal name. The site does not claim to represent a Mahjong association, casino, governing body, or every Singapore playing group.
Questions, corrections, accessibility concerns, privacy requests, and bug reports can be sent through the site feedback form without exposing the creator or visitor email address publicly.
How rule content is produced
The guides are written for this specific implementation rather than copied from a generic Mahjong rules summary. Shared data powers both the playable game and public reference tables wherever practical, including payout rows and special-hand definitions.
Development and editing tools may assist implementation, but published rule claims are checked against the game engine, source data, and automated regression fixtures before deployment.
Ruleset methodology
- Describe the exact behavior enforced by the current SG Mahjong engine.
- Separate configurable settings from fixed rules.
- Show complete tile examples for important hand shapes and calls.
- Verify scoring examples against the same calculation functions used by results.
- State when local house rules may differ instead of presenting one implementation as universal.
- Update the guides when validated gameplay behavior changes.
Corrections and accountability
If a guide disagrees with the live game, the engine and fixtures are inspected before either the guide or implementation is changed. Reports are reviewed as potential rule, content, accessibility, privacy, or gameplay issues.
The public guides were last reviewed on August 5, 2026. Material corrections are recorded in the project update history before deployment.
