MahjongSetup editorial policy.

Research should answer the decision.

Every guide should identify the reader’s setup problem, name the constraint that changes the choice, and use sources appropriate to the claim. Search ideas help prioritize work; they do not become traffic promises, product facts, or evidence of a ranking opportunity.

• Primary sources support manufacturer, retailer, league, or rules claims.
• Community questions reveal vocabulary and friction, not universal dimensions.
• Calculations show their inputs and limits.
• Volatile product information is dated and rechecked before publication.

Products need an exact identity.

A product recommendation requires the exact model or listing, selected variant, bundle contents, destination, and image-use decision to agree. Historical PASS labels, guessed prices, familiar brands, and attractive thumbnails do not clear that gate.

Paid retailer actions appear only beside a relevant recommendation with a visible disclosure and sponsored link qualification. No rating, review, price, availability, quality claim, or Product offer is invented.

Copy should be direct and useful.

Pages answer the practical question near the top, use headings that describe the reader’s job, and stop when the next useful action is clear. Product coverage stays uneven when only one option solves the reader’s constraint; the site does not pad a page with symmetrical alternatives.

MahjongSetup does not reproduce NMJL card scans, hands, or other copyrighted card content. It sends readers to the official source for that resource.

Updates and corrections stay visible.

Listings, bundles, rules resources, and shipping terms can change. When a material change affects identity, fit, included pieces, destination, or a calculation, the page is rechecked and the claim is narrowed, updated, or removed instead of silently carried forward.

Published pages carry a review date when a claim is likely to change. Research that has not cleared publication is kept outside public routes.

Publication requires a clear standard.

A page is ready when its sources, ownership, maintenance plan, and reader-facing purpose are clear. Commercial pages also need exact product evidence and disclosures. Unpublished research stays outside the public site rather than being presented as a recommendation.
