Should I play differently at an American Mahjong tournament?

Yes, a little, and mostly in three places. Defend harder, because throwing the winning tile costs you points and costs more the more exposures the winner shows. Finish small hands rather than chase big ones, because bonuses are added, not doubled. And play faster, because a game that is not finished when time is called scores nothing for anyone.

The careless discard finally has a price

At home, the player who throws the winning tile pays double and everyone shrugs. At a tournament that throw comes off your own score, and the winner collects none of it. The penalty climbs with the winner's exposures: 10 points when they showed one exposure or none, 20 for two, 25 for three or more.

So the information that decides the cost of your discard is sitting face up across the table. Before you let go of a risky tile, look at who has two or more exposures and what they need. A player who defends only when it feels urgent at home should defend sooner here.

Win small, and win often

Tournament scoring keeps the value printed on the card and then adds flat bonuses: 10 for a self-pick, 20 for a jokerless hand. Nothing doubles. A big hand is worth less, compared with an ordinary one, than it would be at your kitchen table.

That changes the arithmetic of ambition. While you spend the whole wall assembling something grand, somebody else finishes an ordinary hand and your points never arrive. Several modest wins outscore one magnificent hand that came in once, if at all.

The clock is a player at the table

A round is four games in a little under an hour, and a game still unfinished at time scores zero for all four players. A slow table costs all four of its players at once, while the faster tables around them keep scoring.

Decide quickly, and know your card well enough that you are not reading it fresh each turn. If the early games have run long, any one player may stop the second Charleston, and at a tournament that is a sensible way to buy back minutes. A wall game also pays 10 to every hand still alive, so keeping your hand alive is worth something even when it is not coming in.

Spend the first game learning the table

At home you already know who plays fast, who hoards Jokers and who never stops the Charleston. At a tournament you sit with strangers, and that quiet knowledge is gone. Use the first game of a round to watch: what each player passes, how quickly they call, what their exposures say. The next three games are where that watching pays.

Before you go, ask the director for the rules sheet and read it at home. Events differ in small ways, and the sheet settles them. Then set yourself a goal you control, such as no misnamed discards or no careless throws, rather than a place on the leaderboard.
