Hu Mahjong is a simple, fast-paced 4 player mahjong variant designed to scale to 3 and 2 player settings while remaining competitive. It emphasizes value creation and impeccable defense.
Key Points
- No set dead wall length; game draws the moment any player's discard pond reaches a certain length, notwithstanding calls made (18 in 4 player, 20 in 3 player, 22 in 2 player).
- Hands are valued by the patterns they exhibit. A hand with no observable pattern is not eligible for a win.
- Other players pay equally in the event of a self-draw win, regardless of their seat wind.
- Discarder pays entirely.
- Sacred discard (furiten) observed. Discards are arranged neatly in players' individual ponds. If they've discarded any tile that can complete their hand (obtaining their desired pattern or otherwise), a player is barred from winning by discard and can only win by self-draw.
- Flowers need not be declared immediately.
Setup
- All tiles in a standard set are used. Flowers are optional, but recommended.
- Starting points are 30000 in 4 player, 35000 in 3 player, and 40000 in 2 player.
- North seat omitted in 3 player. North and West seat omitted in 2 player.
- Chow call is always available towards the player to your left (or your only opponent in 2 player).
Payout Scheme
- Win by self-draw: ×1 base points from other player(s)
- Win by discard (4/3/2 player): base points ×3/×2.5/×2
- Ready hand at exhaustive draw: 1000 from player(s) with no ready hand(s)
- Heavy penalty (for game-ruining errors): 4000 to other player(s)
- The dealer's winning hand is awarded bonus 100 base points for each repeat in their dealership (this bonus does not carry over to the next round).
- Upon reaching a dealer's eighth repeat, everyone's winning hands are awarded 4000 more base points. The seat winds rotate regardless of the hand's outcome.
- Patterns can stack freely across categories. However, patterns supersede those in the same category that they already imply (e.g. Two Pure Sequences Twice stacks with All Sequences despite always going hand-in-hand, but Two Pure Sequences Twice supersedes Two Pure Sequences and are never scored together).
- Hand scores are limited to 8000 base points. That said, there exist rare double to quadruple limit hands. Only the most valuable one is scored in the unlikely event of multiple limit hands occurring together.

- Win by self-draw (4/3/2 player): 18300/12200/6100
- Win by discard (4/3/2 player): 18300/15250/12200
Wind Rotation and Winning the Game
The seat winds rotate whenever:
- A non-dealer wins a hand.
- The dealer does not have a ready hand at exhaustive draw.
- The dealer's eighth repeat concludes.
Otherwise, everyone retains their current seat wind and a repeat is played.
After each player has had a chance to be the dealer, a new round begins with the next prevailing wind.
The player with most points by the end of the South round wins. In 2 player, the last dealer can win the game outright if they are in the lead and win one hand.
