What it is

MahjongBoss is a first-party browser site for single-player tile-matching mahjong solitaire (also called Shanghai solitaire / mahjongg). You clear stacked boards by matching free identical pairs — not four-player table mahjong, not an NMJL practice app, and not an Amazon download.

Who it’s for

Players who want a citeable free, no-download solitaire mahjong site with named variants (Relax, Classic turtle, timed, levels, card tiles), rather than Microsoft Mahjong, Arkadium, Solitaire Bliss, TrySolitaire, Brainium, MobilityWare, mahjongsolitaire.games, or other side-game pages already on disk.

Why it’s listed

Plaza needs an unused first-party solitaire / puzzle mahjong URL with loadable rules copy and mode names.

• Homepage (https://mahjongboss.com/) returned 200 on 2026-09-24. Title framing: “Play Free Mahjong Solitaire Online | MahjongBoss.” Headline: “Play free mahjong solitaire online.” Core claim: match free tiles on a stacked board; no download, no account. Tagline strip: “Shanghai solitaire · No download · No signup.”
• Modes named on-page: Mahjong (no helpers); Mahjong Classic (144-tile turtle pyramid, five layers); Mahjong Relax (no timer, unlimited undo); Mahjong Time (against the clock); Mahjong Real (eighteen progressive levels); Mahjong Cards (playing-card tiles).
• Rules / identity copy on-page: a free tile has nothing on top and at least one long side open; site explicitly distinguishes this puzzle from four-player Chinese mahjong and from connect-style path puzzles.
• Access / pricing FAQ on-page: “Every mahjong game here is 100% free mahjong online—no download, no account, and no paywall.” HTML5 browser play on desktop, tablet, or phone.

Facts above are what the official page showed on the check date. Mode names and board catalogs can change.
