## What is MJ Actuary?

MJ Actuary is a scorekeeper for Hong Kong Mahjong, Hong Kong-style Taiwan
Mahjong and Running Horse. It does not play the game — it settles it. Record
who won, from whom, and for how much, and every payment is worked out for
you.

HONG KONG MAHJONG (13 tiles)
Count your own faan; the app converts it. Half-spicy or full-spicy doubling,
a cap you choose, and three ways to split a discard win — 全銃, or either
half-銃 convention. Self-draw collects double from all three. Minimum faan to
win is configurable. A 包 switch covers robbing a kong and 包牌, where one
player carries the whole hand.

HK-STYLE TAIWAN MAHJONG
• Dealer bonus and consecutive dealer streaks
• Self-draw and discard settlement
• Pull and Kick (拉／踢) debt, including break-cable and third-party settlement
• Draw jackpot
• Multi-Win (一炮多響) with Double Win and Triple Win bonuses
• Instant events: Snake, Triple Dice, and the Chase family
• Kong settled the moment it is declared

RUNNING HORSE (跑馬仔)
No hand patterns and no fan — every action carries a fixed value you set.
Self-draw, concealed kong, added kong, exposed kong. Up to eight horses
(獎馬) on a self-draw, each one adding another full self-draw. The winner
takes the next deal; a drawn hand keeps it.

BUILT FOR THE TABLE
Four seats laid out as you actually sit. One tap to record a win, press and
hold for a multi-win. Running totals stay on screen, so nobody has to ask.

YOURS TO CONFIGURE
Every rule above can be switched off or re-valued, per game type. Play the
rules your table plays.

## Version history (last 5 releases)

### 1.2.0 — 2026-09-22

Hong Kong Mahjong is here — the 13-tile game, scored the way your table
plays it.

Count your faan as usual and the app does the rest: the doubling table
(half-spicy or full-spicy), the cap, and who pays what. A win off a discard
splits three ways depending on your table — 全銃, or either half-銃
convention — and a self-draw collects double from all three. Minimum faan to
win is yours to set; three is standard.

There is a 包 switch for the two cases where one player carries the whole
hand: robbing a kong, and 包牌. Tap it, name the player, done.

No dealer bonus, no streak — the dealer keeps the deal on a win and, by
default, through a drawn hand.

Also in this release:
• Player avatars now fill their circles instead of floating on a colour disc
• The History tab has proper round badges, with the hand number set into the
  tile instead of squeezed underneath

### 1.1.0 — 2026-08-29

Running Horse (跑馬仔) is here — a whole new way to keep score.

Also known as 槓牌, Running Horse has no hand patterns and no fan at all. Every action is worth a fixed amount you set yourself: self-draw, concealed kong, added kong and exposed kong. Tap a player, tap what happened, done. There is no fan picker to scroll.

Horses (獎馬) — after a self-draw, flip up to eight horse tiles. Each one that hits adds another full self-draw, so a lucky hand can pay nine times the base. Enter how many hit and the rest is worked out.

Winner takes the deal, and a drawn hand keeps it where it is. No round winds, no dealer streak.

Also in this release: 
• Playable game modes now come first in the mode picker 
• Every Running Horse value can be re-tuned to match your table 
• Win off a discard is off by default, matching how most tables play

### 1.0.10 — 2026-08-10

Special rules from the Hong Kong-style Taiwan rulebook are here.

Multi-Win (一炮多響) — when one discard is claimed by two or three players, record them all in one go. Press and hold a player to start, then tap the others who won off the same tile. Every winner enters their own hand value, and the Double Win / Triple Win bonus is added automatically.

Instant Events — Snake, Triple Dice and the whole Chase family now settle on the spot, without waiting for a hand to finish. Find them next to Kong in the scoring sheet.

Also in this release: • Fixed three cases where recording a score could silently do nothing • Both new rules can be switched off, with adjustable values, in game settings • Updated for the latest iOS

### 1.0.9 — 2026-06-29

- Added Kong scoring based on the configured Base Bet.
- Added final settlement payment view for easier end-game balancing.
- Final settlement now clears settled Pull/Kick indicators.
- Remaining bonus pool is distributed evenly when final settlement is completed.
- Improved settlement sharing reliability on iOS.

### 1.0.7 — 2026-06-13

• Added Break Cable settlement choices at every third Pull
• Fixed Pull debts being settled incorrectly during consecutive wins
• Improved app startup speed
• Added in-game player name editing
• Fixed Reduce Motion navigation
• Reduced ad frequency to once every 10 rounds
