MJ Actuary – Mahjong Scorer

Hong Kong Mahjong is here. Count your faan; the app handles the doubling table, the cap and who pays what. Three modes, one scorekeeper.

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.
