About this game

Mahjong, beautifully made: four great tables, more than 140 lessons and a lamplit 3D table. Whether you have never held a tile or you count tai in your sleep, there is a seat for you.

Singapore Mahjong and Gwai Lou solitaire are free to play in full. Hong Kong, 3 Kaki and Riichi are free to try, then yours with a one-time unlock.

Five Ways To Play
• Singapore Mahjong: tai, flowers, animals and Bao, played the Straits way.
• Hong Kong Old Style: faan, not tai. Bigger hands, and the discarder pays it all.
• Malaysian 3 Kaki: three players, one suit and four Fly jokers.
• Japanese Riichi: yaku, dora, riichi sticks, furiten and full hanchan scoring.
• Gwai Lou Mode: tile-matching solitaire, just for fun, with a new Daily Board every day.
Every table has its own rules, its own scoring and its own orchestral theme.

Learn It Properly
• 33 Singapore lessons in six chapters, from your first tile to Bao and payments. Each one runs Observe, Try It Yourself, then Explain, with a fresh example whenever you want one.
• Learn any table from zero: full courses for Riichi, Hong Kong and 3 Kaki, each with First Steps, a Guided Hand and practice, or a short What's Different path if you already play Singapore.
• Practice from real hands: What Would You Discard?, Read The Discards, Push Or Fold and Count This Hand.
• Not sure where to start? Five quick questions suggest your first lesson.
• Mahjong Terms: a searchable glossary, with the other names players use.

A Coach At The Table
• Start with a Guided Hand, move on to a Scored Hand, then play a full match against computer players.
• Hint and the Hand Guide explain your options while the game waits. The guide's pick shows in gold, and its advice uses only your tiles and what everyone can see.
• No clock and no rush in solo play: take as long as you like.

Play With Friends
Host a private table and share its link. Only the host needs Host A Table or Complete; friends join free from the app or straitsmahjong.com, and computer players fill empty seats. An internet connection is needed.

Scoring, Made Clear
• Score Details shows every tai, the tiles that earned it and exactly who pays whom.
• Compare The Tables scores one hand by Singapore, Hong Kong and 3 Kaki rules, side by side.
• House Rules set the tai minimum and limit, Shooter Pays and more.

A Table Worth Sitting At
• A real 3D table with a walnut rail and lamplit felt, in portrait or landscape.
• Seven tile sets, from Imperial Jade and Peranakan Rose to Zodiac Pixels.
• English, 中文, Bahasa Melayu and தமிழ். Every table speaks its own words too: Zi Mo and Qing Yi Se in Singapore, Sik Wu and faan in Hong Kong, Fei in 3 Kaki.
• An orchestral theme for every game, with music and sound effects you can switch on or off.
• Larger text and calmer motion whenever you want them.

At The Movies
Mahjong's most famous film scene, replayed tile by tile on our own table: who wanted what, what that discard really meant, and every tai counted.
