Play, learn, and share a table
SG Mahjong is a free browser game built for quick practice and private games with friends. The same table handles the tile wall, legal calls, win checks, tai totals, and optional chip settlement, so new players can focus on the hand instead of calculating every result manually. Start immediately without creating an account or installing an app, then use the connected guides whenever you want to check a rule in more detail.
If this is your first game, begin with the step-by-step How to Play guide. Experienced players can go directly to the complete rules reference for the exact behavior enforced by this table.
Choose your mode
Singleplayer seats you against three AI opponents, which makes it easy to practise turns, calls, winning shapes, and scoring at your own pace. For multiplayer, host a private room and share its four-character room code. Friends join with that code and a player name; empty seats can remain as bots. There is no public lobby, signup form, or download between your group and the table.
Singapore joker rules
Choose 0, 4, 8, 12, 16, or 20 Fei tiles before starting. A drawn Fei stays in the hand and cannot be discarded. During concealed win checking, Fei can substitute in sequences, Pungs, or the eyes, but it cannot be used to Chi, Pung, or Kong another player's discard. Read the full Fei rules before choosing a higher-joker game.
Legal wins and scoring
The Tai Threshold is the minimum for a Zi Mo, or self-drawn win. A discard win needs that threshold plus one tai. Ordinary scoring patterns can stack when they apply, while automatic special hands bypass the ordinary winning threshold and replace ordinary pattern scoring. Valid Animals and seat-matched Flowers or Seasons still remain as bonus tai. The game recognizes hands including Big Three Dragons, Thirteen Wonders, Kan Kan Hu, and Shi Ba Luo Han. Review the tai scoring guide and special-hand guide for the detailed totals.
Optional settlement
Chip settlement begins only when you choose a payout table and enter Starting Chips. Available tables are $0.10 / $0.20, $0.30 / $0.60, and $1 / $2. Without Shooter, the discarder pays the larger discard amount while the other non-winners pay the smaller amount. With Shooter enabled, only the discarder pays on a discard win. On Zi Mo, all three opponents pay. Max Cap Tai limits ordinary settlement, while Caps Max Tai for Special separately controls special-hand payout rows. See the payout table guide for examples. All balances are virtual play-money chips with no real-world value.
The table continues through drawing, discarding, Chi, Pung, Kong, replacement tiles, round results, dealer progression, and the configured winning checks. If no legal win resolves first, the hand ends when the whole wall reaches 15 tiles. Use singleplayer to learn the rhythm, then host a room and send the code to your usual Mahjong group.
