Scoring: Han and Fu

Points come from han and fu. Reading the table is enough to start, and working it out yourself takes one formula.

Count the han first

When you win, add up the han of every yaku plus your dora. That is the hand's han.

For example: a round-wind triplet (1 han), one red five (1 han) and two dora (2 han) make 4 han.

Points double with each han. From 5 han up you do not need fu at all; just read the "Mangan and above" table.

Then the fu

Fu reflect how the hand is built. Most hands are 30 fu or 40 fu. A few common cases are worth remembering:

  • Pinfu by tsumo: 20 fu.
  • Seven pairs: always 25 fu.
  • Closed ron or hands with few triplets: usually 30 or 40 fu.
  • Calls and lots of triplets (especially concealed triplets of terminals and honors) raise the fu.

The results screen shows the han and fu for you, so you never have to count them yourself.

Point table (up to 4 han)

Each cell shows the points for a ron win as "non-dealer / dealer". A dealer win pays 1.5 times as much.

A tsumo win is split among the other three for about the same total: on a non-dealer tsumo the dealer pays half and each non-dealer a quarter; on a dealer tsumo the three players pay equal shares.

Mangan and above

With enough han, the score becomes a fixed amount and fu no longer matter. Any hand of 4 han 40 fu or 3 han 70 fu and up that would go over a mangan is also scored as a mangan.

Yakuman—32,000 / 48,000

A yakuman (such as thirteen orphans, big three dragons or four concealed triplets) is 32,000 / 48,000 points. By default 13 han or more count as a counted yakuman, and thirteen-sided thirteen orphans, single-wait four concealed triplets, pure nine gates and big four winds count as double yakuman.

Counting fu (for the curious)

  1. Start with 20 fu.
  2. Closed ron +10; tsumo +2 (not for pinfu tsumo).
  3. Each triplet: open simples 2, concealed simples 4; open terminals or honors 4, concealed 8. A kan is worth 4 times a triplet.
  4. A pair of value tiles +2; a closed, edge or pair wait +2.
  5. Round up to the next 10.

The formula: base points = fu × 2^(han + 2). A non-dealer ron gets base × 4 and a dealer ron base × 6, rounded up to the next 100. For example, 1 han 30 fu: 30 × 8 × 4 = 960, rounded up to 1,000 points.

Honba and riichi sticks

  • Honba: after a dealer repeat or a draw, the center shows "1 honba", "2 honba" and so on. Each honba adds 300 points to the next win.
  • Riichi sticks: the 1,000-point sticks on the table. The next player to win takes them all.

Everyone starts with 25,000 points. Points only move between the four players; the total never changes. How placings and final points are worked out is in How a match works.
