Singapore Mahjong: Animal Tiles and House Rules

Singapore mahjong takes the thirteen-tile hand familiar from Hong Kong play and bolts four extra tiles onto it: a cat, a mouse, a rooster and a centipede. Those four animals are the feature nobody else has, and they are why a Singapore game feels busier than the game it grew out of – there is more on the table to care about, and more of it belongs to players who are not currently winning the hand.

Almost everything else about the variant is local. What the animals are worth, what it takes to declare a win, whether a big hand is capped and how the scoring unit turns into money are all house settings, and they differ enough between one Singapore table and the next that the first ten minutes of any game are best spent agreeing them out loud.

The animal tiles, the feature nobody else has

A standard mahjong set contains 144 tiles – 108 suited, 28 honours and 8 flowers and seasons. A Singapore set adds the four animals on top, which is why it runs to 148 rather than 144.

Like flowers and seasons, the animals are bonus tiles rather than building blocks: they are not part of any set you are trying to complete, and they are handled separately from the hand in front of you. Cat with mouse and rooster with centipede is the usual pairing convention – predator with prey – but what a pair is worth, and when that value changes hands, is a house matter.

That is the one thing most worth asking about before you sit down at an unfamiliar Singapore table. Nobody argues about how the tiles are drawn; the arguments are about what the animals paid and to whom, and they are entirely preventable by settling it first.

Twelve bonus tiles instead of eight

A Singapore set carries the standard eight flowers and seasons alongside the four animals, so twelve of the tiles in play are bonus tiles rather than hand-building material. That is an unusually large number, and it is the main reason the variant has a reputation for keeping everybody involved: a player who is nowhere near a winning hand can still have something happening in front of them.

How each of those twelve counts is exactly the part that varies. Flowers and seasons are handled differently between rulesets, the animals are not standardised at all, and no federation publishes a canonical Singapore schedule. Wikipedia’s survey of mahjong scoring systems is the best available overview of how the major families differ, and for a codified ruleset to compare against, the European Mahjong Association runs its tournaments under the Mahjong Competition Rules.

How it compares with the game next door

Anyone arriving from the thirteen-tile game will find the underlying structure familiar. Tiles are drawn and discarded the same way, sets are built the same way, and the shape of a finished hand is the shape you already know. What changes is the extras and the settlement conventions wrapped around them.

Scoring varies widely between rulesets, and Singapore sits at the loose end of that range – the sheet your table uses is the sheet that counts, and there is no published authority to appeal to when somebody disagrees. Our guide to Hong Kong mahjong rules and scoring is the cleanest baseline to compare against, and if regional contrasts interest you, sixteen-tile Taiwanese mahjong is built on very different assumptions again.

What to agree before the first deal

Because so much of this variant is house-set, a short conversation at the start does more for the evening than any amount of tactical skill. Run through this list while the tiles are being shuffled.

  • The scoring sheet itself. Which patterns your table recognises, and what each is worth. Write it down if the group is new to each other.
  • The animals. What a single animal does, what a matched pair does, and whether holding all four is treated as anything special.
  • Flowers and seasons. How they are counted, and whether a complete group is treated differently from the individual tiles.
  • Whether there is a ceiling. Some tables cap what a single hand can be worth and some do not, and it changes how you play every hand.
  • The rate. How the scoring unit converts into money or points – flat rates and doubling ladders are both common, and they are nothing like each other.
  • Responsibility conventions. Ask whether the table uses any and what they are. These are the rules newcomers most often meet the expensive way.
  • What happens in a dispute. Agreeing in advance that the host’s call stands, or that a contested hand is replayed, stops a two-minute disagreement from ending the night.

Strategy for a fast, chatty table

  1. Play the sheet in front of you, not the one you read online. The values that matter are the ones this table agreed, and they may not be the ones you learned.
  2. Know what your hand is currently worth. Players who can total their own hand without stopping to think make better decisions about whether to push or fold.
  3. Watch what everybody else has exposed. Bonus tiles and claimed sets are public information, and they are the clearest signal of who is close.
  4. Decide early whether you are playing to win the hand or to end it. Both are legitimate; drifting between them is what loses money.
  5. Slow down when a hand is obviously about to finish. The last few discards before somebody wins are where most avoidable losses happen.

What newcomers get wrong

  • Treating an animal tile as junk because it does not fit into a set. Bonus tiles are not spare tiles.
  • Sitting down without agreeing the sheet, the rate and the animal payouts first. Ten minutes of admin prevents an hour of argument.
  • Assuming the rules travel. A sheet learned at one Singapore table is a starting point for the next, not a standard.
  • Keeping score in somebody’s head. Use paper or a phone, because reconstructing a disputed total three hands later is impossible.
  • Being too polite to ask. Every regular at that table learned the house conventions by asking, usually after losing something to them.

Playing Singapore mahjong in Sydney

One practical warning: standard 144-tile sets include flowers and seasons but not the four animals, so a set bought or hired for Hong Kong play will be missing the tiles this variant is built around. Most groups solve it by adding a small animal tile set to their existing tiles, which is inexpensive and needs nothing more than a check that the tile size matches.

We hire the Size 40 Green Chinese 144-tile set from A$20 for a weekday sitting, and table, stools and tiles together from A$70, collected from Brodie Spark Drive in Wolli Creek or delivered anywhere in Greater Sydney. Bring your own four animals, take the tiles and table from us, and the only thing left to argue about is the sheet.

If you are hosting rather than joining, the setup matters more than people expect. Four players need a square table they can all reach across, chairs at a height that suits a long sitting, and enough light over the middle that nobody is squinting at a discard. Keep drinks off the playing surface, put snacks that leave nothing on your fingers within reach rather than on the felt, and agree a finishing time before you start – an evening ends far more happily when everybody knew in advance which hand was the last one.

Enjoying the regional detours? Our survey of rare mahjong variations covers games that change the wall itself, and if the animal tiles have you curious about bonus mechanics generally, the meaning behind the tile symbols is a good companion read.

Questions that come up at a Singapore table

What are the animal tiles in Singapore mahjong?

Cat, mouse, rooster and centipede. They are bonus tiles rather than part of a set, usually paired predator with prey – cat with mouse, rooster with centipede – and what they are worth is set by the house rather than by any published standard.

How many tiles are in a Singapore mahjong set?

Usually 148: the standard 144 tiles plus the four animals. Sets sold for Hong Kong or Taiwanese play will not include the animals.

Can you play Singapore rules without animal tiles?

You can play the underlying hand structure, but you lose the mechanic that defines the variant. Adding an inexpensive set of four animal tiles to a standard set is the simplest fix.

What should a table agree before the first deal?

The scoring sheet, the rate that converts it into money or points, what the animals do, how flowers and seasons are counted, whether there is a ceiling on a single hand, and what happens if two people remember a convention differently. Five minutes at the start prevents most of the arguments that would otherwise arrive at the end.

How many players do you need?

Four, as at any standard mahjong table. A fifth person is genuinely useful for a long evening, sitting out a hand at a time so that people can take breaks without stopping the game.

Is Singapore mahjong good for a mixed-experience group?

It suits one well, because there is something happening for everybody rather than only for whoever is closest to winning. The thing to watch is the house sheet: with more moving parts to agree, an unfamiliar group should settle the details before the first tile is drawn rather than halfway through the night.
