General Rules
General Rules
Four Seas Mahjong is an accessible mahjong ruleset built around the idea of hand-building, combining entertainment with competitive depth.
Its hand-building philosophy uses rule design to encourage players to develop larger, more elegant, and more difficult hands on top of basic winning patterns, rather than only racing to quick small wins.
For both casual and competitive players, Four Seas Mahjong provides two core rule levels, Basic and Standard, plus Beginner Level and Advanced variants for easier learning and transition.
Rule Levels
Rule Level - Version - Intended Use - Yaku Count - Features
Basic Rules - Beginner Level - For new players - 7 - Basic mahjong rules and operations, with no minimum-score requirement
Basic Rules - Basic - For casual players - 18 - Introduces the hand-building system and its main lines, with a higher winning threshold
Standard Rules - Advanced - A transition between Basic and Standard - 49 - Expands whole-hand yaku and sequence-based yaku; minimum score differs for self-draw and discard wins
Standard Rules - Standard - Competitive mahjong rules - 100 - Adds triplet, mixed sequence-triplet, and seven-pairs yaku, limit hands, and buried tiles
Common Game Rules
Four Seas Mahjong is played by four players. When one player wins, the current hand ends. There is no dealer continuation.
A half game consists of two rounds, and a full game consists of four rounds. Each player starts each game with 1000 points, and a player's score may go below zero.
The game uses 136 mahjong tiles, including three suits and seven honor tiles. Flower tiles are not used.
Fourteen tiles are set aside as the dead wall. Supplement tiles for kongs are drawn from the end of the dead wall, and the dead wall is not replenished. The hand ends in a draw when only the dead wall remains.
The furiten-like restriction applies: after a player is in tenpai, if that player declines to win on a winning discard made by themselves or another player, they may not win on the same tile before their next draw.
Concealed kongs are revealed immediately.
Kongs are allowed after calls such as chii and pon.
The minimum score required to win differs by rule level.
Multiple-player wins are handled differently by rule level. The Beginner Level and Basic Level use interception of the win, while the Advanced and Standard versions use score interception without blocking the win itself.
