Reading Discards

Read other players from what they claim and what they throw: exposed sets show their plan, and a suit nobody lets go of may be someone’s flush. Put the clues together before you throw a tile they might want.

Every player tells you a little about their hand each turn, by what they throw and what they take. Put those clues together and the table stops being a mystery.

Start With The Claims

Face-up sets are the clearest clues you get.

Two or three sets in one suit, with honours: likely a flush. Three in one suit is a strong warning, and Singapore’s Bao rule makes feeding a full flush very expensive.
Pongs and no Chi: Pong Pong Hu may be coming. Their last wait is often two pairs.
Pongs of dragons or winds: they’re collecting tai. Two dragon Pongs means the third dragon is dangerous, and feeding it can be Bao.
A Chi: that player isn’t on Pong Pong Hu, and if they took it early, probably isn’t chasing a big pattern.

Three Dots sets face up: don’t throw Dots.

Then The Discards

Discards show what a player doesn’t want, and the order says when they stopped wanting it.

Honours early, numbers later: a normal hand building runs. Middle tiles thrown late usually mean their hand is taking shape.
A suit that never appears: if someone has thrown eight tiles and none were Bamboo, they may be keeping Bamboo.
Middle tiles early: unusual. They may be after Pongs, honours, or 1s and 9s.
A held tile let go late: a dragon or middle tile thrown well into the hand often means the player has just gone ready and no longer needs it.

One clue proves little. Two or three pointing the same way are worth acting on.

Tiles That Are Safe For Now

The most reliable read is timing. A tile thrown after a player’s last draw, that they didn’t win on, can’t win for them until they draw again or claim a set. If the player before you throws 3 Characters and the dangerous player says nothing, your 3 Characters is safe against them this turn.

In this game a player who passes a winning tile can’t win on another copy until they draw or declare a set. But a tile thrown long ago isn’t safe now: their hand has changed since.

What You Give Away

Reading works both ways. Throwing every honour on the first three turns says you’re building runs. Claiming two same-suit sets announces a flush. You can’t hide everything, but you can avoid giving the table extra help:

don’t claim sets you don’t need, since each one shows your plan;
throw your flush’s off-suit tiles early, when nobody’s reading yet;
remember the player on your right can Chi your discards: feeding them runs they need speeds up their hand.

Putting It Together

Each turn, glance at the player who looks closest: how many sets they show, what suit they avoid, and what they’ve just let go. Then pick a discard that fits none of it. Safer Discards covers the safest choices once you’ve read the danger.
