# Koi-Koi yaku: every scoring combination and its points

Canonical URL: https://hanafuda.lemme.dev/yaku/

Last updated 26 September 2026

Koi-Koi (often written koi koi) is scored with yaku, named sets of cards worth from 1 to 10 points before extra cards and doubling. This game has 15: 13 you build from your captures, such as Gokō (10) and Inoshikachō (5), and 2 lucky hands that can only be dealt (6 each). The points are those of Nintendo’s published Koi-Koi table; where this game combines yaku differently, Nintendo’s rule is given beside ours.

## Koi-Koi points table

Card values (20, 10, 5 and 1) never score by themselves: only yaku do. A [yaku](https://hanafuda.lemme.dev/glossary/#yaku) made of named cards is complete once you hold them all; the ones marked +1 then gain a point for every further card of the kind. The round’s score is the sum of every yaku the winner holds, then doubled or multiplied as the [scoring page](https://hanafuda.lemme.dev/scoring/) explains.

Every yaku of this game, with its points before any doubling

| Yaku | Points | Cards |
| --- | ---: | --- |
| Five Lights (Gokō) · 五光 gokō | 10 | All five lights |
| Four Lights (Shikō) · 四光 shikō | 8 | Four lights, not the Rain |
| Rain Four Lights (Ame Shikō) · 雨四光 ame shikō | 7 | The Rain and three other lights |
| Three Lights (Sankō) · 三光 sankō | 5 | Three lights, not the Rain |
| Flower Viewing (Hanami de ippai) · 花見で一杯 hanami de ippai | 5 | Curtain + Sake cup |
| Moon Viewing (Tsukimi de ippai) · 月見で一杯 tsukimi de ippai | 5 | Moon + Sake cup |
| Boar, Deer, Butterflies (Inoshikachō) · 猪鹿蝶 inoshikachō | 5 | Boar + Deer + Butterflies · +1 per other animal |
| Red Poem Tanzaku (Akatan) · 赤短 akatan | 5 | The poem tanzaku of Pine, Plum and Cherry · +1 per other tanzaku |
| Blue Tanzaku (Aotan) · 青短 aotan | 5 | The blue tanzaku of Peony, Chrysanthemum and Maple · +1 per other tanzaku |
| Red & Blue Tanzaku (Akatan Aotan no Chōfuku) · 赤短・青短の重複 akatan aotan no chōfuku | 10 | All six of them (instead of Akatan and Aotan) · +1 per other tanzaku |
| Animals (Tane) · タネ tane | 1 | Any 5 animals, the Sake cup included · +1 per animal after the 5th |
| Tanzaku (Tan) · タン tan | 1 | Any 5 tanzaku · +1 per tanzaku after the 5th |
| Plains (Kasu) · カス kasu | 1 | Any 10 plains, the Lightning included · +1 per plain after the 10th |
| Four of a Month (Teshi) · 手四 teshi | 6 | Dealt all 4 cards of one month |
| Four Pairs (Kuttsuki) · くっつき kuttsuki | 6 | Dealt 4 pairs of different months |

Names follow the game’s own screens: the five 20-point cards are the *lights*, the 10-point cards the *animals* (tane), the 5-point cards the *tanzaku*, and the 1-point cards the *plains* (kasu). Gokō, Shōbu and Inoshikachō are written with macrons here; you will also see them as Goko, Shobu and Inoshikacho.

## Light yaku: Gokō, Shikō, Ame Shikō and Sankō

The five lights are the Crane (January), the Curtain (March), the Moon (August), the Rain (November) and the Phoenix (December). Only one light yaku counts at a time: the one that uses the most lights. The Rain, the Willow card with the calligrapher Ono no Michikaze (Ono no Tōfū) under his umbrella, counts differently: four lights with the Rain are Ame Shikō (7) instead of Shikō (8), the Rain and two other lights make no yaku, and all five are still Gokō (10). [The light yaku in detail](https://hanafuda.lemme.dev/yaku/hikari/).

### Five Lights (Gokō)

10 points 五光 gokō

  Rain

- ![Phoenix – Paulownia, December, Light (20 pts)](https://hanafuda.lemme.dev/cards/kiri_phoenix.svg)

  Phoenix
  桐に鳳凰
  December · Light (hikari) · 20 pts

All five lights. Gokō takes the place of every smaller light yaku, so it is worth 10, never 10 + 8 + 5. It still adds up with Hanami and Tsukimi, which use the Curtain and the Moon: with the Sake cup as well, the total is 10 + 5 + 5 = 20.

### Four Lights (Shikō)

8 points 四光 shikō

- ![Crane – Pine, January, Light (20 pts)](https://hanafuda.lemme.dev/cards/matsu_crane.svg)

  Crane
- ![Curtain – Cherry, March, Light (20 pts)](https://hanafuda.lemme.dev/cards/sakura_curtain.svg)

  Curtain
- ![Moon – Pampas, August, Light (20 pts)](https://hanafuda.lemme.dev/cards/susuki_moon.svg)

  Moon
- ![Phoenix – Paulownia, December, Light (20 pts)](https://hanafuda.lemme.dev/cards/kiri_phoenix.svg)

  Phoenix

The four lights other than the Rain. At 8 points it reaches this game’s doubling line on its own, so a Shikō with no other yaku scores 16 with the default room setting (and 16 under Nintendo’s rule, which doubles from 7).

### Rain Four Lights (Ame Shikō)

7 points 雨四光 ame shikō

- ![Crane – Pine, January, Light (20 pts)](https://hanafuda.lemme.dev/cards/matsu_crane.svg)

  Crane
- ![Curtain – Cherry, March, Light (20 pts)](https://hanafuda.lemme.dev/cards/sakura_curtain.svg)

  Curtain
- ![Moon – Pampas, August, Light (20 pts)](https://hanafuda.lemme.dev/cards/susuki_moon.svg)

  Moon
- ![Rain – Willow, November, Light (20 pts)](https://hanafuda.lemme.dev/cards/yanagi_rainman.svg)

  Rain

The Rain with three of the other lights. It is worth 7, one below this game’s doubling line, so on its own it stays at 7.

> **Rules differ**
>
> Nintendo doubles any total of 7 or more, so the same Ame Shikō scores 14 there. See [doubling at 8 or 7](https://hanafuda.lemme.dev/scoring/#doubling).

### Three Lights (Sankō)

5 points 三光 sankō

- ![Crane – Pine, January, Light (20 pts)](https://hanafuda.lemme.dev/cards/matsu_crane.svg)

  Crane
- ![Curtain – Cherry, March, Light (20 pts)](https://hanafuda.lemme.dev/cards/sakura_curtain.svg)

  Curtain
- ![Moon – Pampas, August, Light (20 pts)](https://hanafuda.lemme.dev/cards/susuki_moon.svg)

  Moon

Any three lights except the Rain. The Rain with two other lights makes no yaku at all: it needs a fourth light to count, as Ame Shikō.

## Sake cup yaku: Hanami and Tsukimi

The Chrysanthemum’s Sake cup turns two lights into a party: a drink under the cherry blossoms, or under the full moon. The same cup serves both, so the Curtain, the Moon and the Sake cup together score 5 + 5 = 10.

### Flower Viewing (Hanami de ippai)

5 points 花見で一杯 hanami de ippai

- ![Curtain – Cherry, March, Light (20 pts)](https://hanafuda.lemme.dev/cards/sakura_curtain.svg)

  Curtain
  桜に幕
  March · Light (hikari) · 20 pts

  Sake cup
  菊に盃
  September · Animal (tane) · 10 pts

The Curtain and the Sake cup: Hanami de ippai, “a cup under the blossoms”, also called hanami-zake. [More on Hanami de ippai](https://hanafuda.lemme.dev/yaku/hanami-de-ippai/).

### Moon Viewing (Tsukimi de ippai)

5 points 月見で一杯 tsukimi de ippai

- ![Moon – Pampas, August, Light (20 pts)](https://hanafuda.lemme.dev/cards/susuki_moon.svg)

  Moon
  芒に月

  Sake cup
  菊に盃
  September · Animal (tane) · 10 pts

The Moon and the Sake cup: Tsukimi de ippai, “a cup under the moon”, or tsukimi-zake. [More on Tsukimi de ippai](https://hanafuda.lemme.dev/yaku/tsukimi-de-ippai/).

Both viewing yaku are always on in this game. Some house rules let a Willow (rain) card spoil them, once captured or while it lies on the table depending on the table: that is [ame-nagare](https://hanafuda.lemme.dev/glossary/#ame-nagare), and this game does not use it.

## Animal yaku: Inoshikachō and Tane

### Boar, Deer, Butterflies (Inoshikachō)

5 points, +1 per other animal 猪鹿蝶 inoshikachō

- ![Boar – Lespedeza, July, Animal (10 pts)](https://hanafuda.lemme.dev/cards/hagi_boar.svg)

  Boar
  萩に猪

- ![Butterflies – Peony, June, Animal (10 pts)](https://hanafuda.lemme.dev/cards/botan_butterfly.svg)

  Butterflies
  牡丹に蝶
  June · Animal (tane) · 10 pts

The Boar of July (bush clover), the Deer of October (maple) and the Butterflies of June (peony): 5 points, and 1 more for each other animal you hold. In this game Tane counts beside it: with five animals you score both.

> **Rules differ**
>
> Nintendo’s table voids Tane once Inoshikachō is made. The three cards plus the Nightingale and the Geese are Inoshikachō 7 + Tane 1 = 8 here, and 7 under Nintendo’s rule. [All about Inoshikachō](https://hanafuda.lemme.dev/yaku/inoshikacho/).

### Animals (Tane)

1 point, +1 per animal after the 5th タネ tane

![Nightingale – Plum, February, Animal (10 pts)](https://hanafuda.lemme.dev/cards/ume_warbler.svg) ![Cuckoo – Wisteria, April, Animal (10 pts)](https://hanafuda.lemme.dev/cards/fuji_cuckoo.svg) ![Bridge – Iris, May, Animal (10 pts)](https://hanafuda.lemme.dev/cards/ayame_bridge.svg) ![Butterflies – Peony, June, Animal (10 pts)](https://hanafuda.lemme.dev/cards/botan_butterfly.svg) ![Boar – Lespedeza, July, Animal (10 pts)](https://hanafuda.lemme.dev/cards/hagi_boar.svg) ![Geese – Pampas, August, Animal (10 pts)](https://hanafuda.lemme.dev/cards/susuki_geese.svg) ![Sake cup – Chrysanthemum, September, Animal (10 pts)](https://hanafuda.lemme.dev/cards/kiku_sake_cup.svg) ![Deer – Maple, October, Animal (10 pts)](https://hanafuda.lemme.dev/cards/momiji_deer.svg) ![Swallow – Willow, November, Animal (10 pts)](https://hanafuda.lemme.dev/cards/yanagi_swallow.svg)

Any five of the nine animal cards shown above, the Sake cup among them: 1 point, and 1 more for each animal after the fifth, so all nine are worth 5. It adds up with Inoshikachō, Hanami and Tsukimi, which share its cards. [Tane, Tan and Kasu in detail](https://hanafuda.lemme.dev/yaku/tane-tan-kasu/).

## Tanzaku yaku: Akatan, Aotan, Chōfuku and Tan

There are ten tanzaku: three red ones with a poem (January to March), three blue ones (June, September, October) and four plain red ones (April, May, July, November). [Akatan and Aotan in detail](https://hanafuda.lemme.dev/yaku/akatan-aotan/).

### Red Poem Tanzaku (Akatan)

5 points, +1 per other tanzaku 赤短 akatan

- ![Red poem tanzaku – Pine, January, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/matsu_ribbon.svg)

The poem tanzaku of the Pine, the Plum and the Cherry. The Pine and Plum strips read *akayoroshi*, the Cherry strip *miyoshino*. 5 points, and 1 more for each other tanzaku.

### Blue Tanzaku (Aotan)

5 points, +1 per other tanzaku 青短 aotan

- ![Blue tanzaku – Peony, June, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/botan_ribbon.svg)

  Blue tanzaku
  紅葉に青短
  October · Tanzaku (ribbon) · 5 pts

The blue tanzaku of the Peony, the Chrysanthemum and the Maple: 5 points, and 1 more for each other tanzaku.

### Red & Blue Tanzaku (Akatan Aotan no Chōfuku)

10 points, +1 per other tanzaku 赤短・青短の重複 akatan aotan no chōfuku

![Red poem tanzaku – Pine, January, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/matsu_ribbon.svg) ![Red poem tanzaku – Plum, February, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/ume_ribbon.svg) ![Red poem tanzaku – Cherry, March, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/sakura_ribbon.svg) ![Blue tanzaku – Peony, June, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/botan_ribbon.svg) ![Blue tanzaku – Chrysanthemum, September, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/kiku_ribbon.svg) ![Blue tanzaku – Maple, October, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/momiji_ribbon.svg)

All six at once: Akatan Aotan no Chōfuku, “red and blue together”. It counts instead of Akatan and Aotan (10, not 5 + 5 + 10), plus 1 for each of the four plain red tanzaku you also hold.

### Tanzaku (Tan)

1 point, +1 per tanzaku after the 5th タン tan

![Red poem tanzaku – Pine, January, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/matsu_ribbon.svg) ![Red poem tanzaku – Plum, February, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/ume_ribbon.svg) ![Red poem tanzaku – Cherry, March, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/sakura_ribbon.svg) ![Red tanzaku – Wisteria, April, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/fuji_ribbon.svg) ![Red tanzaku – Iris, May, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/ayame_ribbon.svg) ![Blue tanzaku – Peony, June, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/botan_ribbon.svg) ![Red tanzaku – Lespedeza, July, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/hagi_ribbon.svg) ![Blue tanzaku – Chrysanthemum, September, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/kiku_ribbon.svg) ![Blue tanzaku – Maple, October, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/momiji_ribbon.svg) ![Red tanzaku – Willow, November, Tanzaku (5 pts)](https://hanafuda.lemme.dev/cards/yanagi_ribbon.svg)

Any five of the ten tanzaku: 1 point, and 1 more for each tanzaku after the fifth. In this game Tan counts beside Akatan, Aotan and Chōfuku, so all ten tanzaku make Chōfuku 14 + Tan 6 = 20.

> **Rules differ**
>
> Nintendo’s table voids Tan once Akatan or Aotan is made. The three poem tanzaku with the Wisteria and Bush Clover strips score Akatan 7 + Tan 1 = 8 here, and 7 there. Compare the [stacking rules](https://hanafuda.lemme.dev/house-rules/#stacking).

## The plain yaku

Half the deck, 24 cards, are plains worth 1 point each: two in each month from January to October, the Willow’s Lightning, and three in December. One yaku counts them.

### Plains (Kasu)

1 point, +1 per plain after the 10th カス kasu

![Pine plain – January, Plain (1 pt)](https://hanafuda.lemme.dev/cards/matsu_plain_1.svg) ![Pine plain – January, Plain (1 pt)](https://hanafuda.lemme.dev/cards/matsu_plain_2.svg) ![Plum plain – February, Plain (1 pt)](https://hanafuda.lemme.dev/cards/ume_plain_1.svg) ![Plum plain – February, Plain (1 pt)](https://hanafuda.lemme.dev/cards/ume_plain_2.svg) ![Cherry plain – March, Plain (1 pt)](https://hanafuda.lemme.dev/cards/sakura_plain_1.svg) ![Cherry plain – March, Plain (1 pt)](https://hanafuda.lemme.dev/cards/sakura_plain_2.svg) ![Wisteria plain – April, Plain (1 pt)](https://hanafuda.lemme.dev/cards/fuji_plain_1.svg) ![Wisteria plain – April, Plain (1 pt)](https://hanafuda.lemme.dev/cards/fuji_plain_2.svg) ![Iris plain – May, Plain (1 pt)](https://hanafuda.lemme.dev/cards/ayame_plain_1.svg) ![Iris plain – May, Plain (1 pt)](https://hanafuda.lemme.dev/cards/ayame_plain_2.svg) ![Peony plain – June, Plain (1 pt)](https://hanafuda.lemme.dev/cards/botan_plain_1.svg) ![Peony plain – June, Plain (1 pt)](https://hanafuda.lemme.dev/cards/botan_plain_2.svg) ![Lespedeza plain – July, Plain (1 pt)](https://hanafuda.lemme.dev/cards/hagi_plain_1.svg) ![Lespedeza plain – July, Plain (1 pt)](https://hanafuda.lemme.dev/cards/hagi_plain_2.svg) ![Pampas plain – August, Plain (1 pt)](https://hanafuda.lemme.dev/cards/susuki_plain_1.svg) ![Pampas plain – August, Plain (1 pt)](https://hanafuda.lemme.dev/cards/susuki_plain_2.svg) ![Chrysanthemum plain – September, Plain (1 pt)](https://hanafuda.lemme.dev/cards/kiku_plain_1.svg) ![Chrysanthemum plain – September, Plain (1 pt)](https://hanafuda.lemme.dev/cards/kiku_plain_2.svg) ![Maple plain – October, Plain (1 pt)](https://hanafuda.lemme.dev/cards/momiji_plain_1.svg) ![Maple plain – October, Plain (1 pt)](https://hanafuda.lemme.dev/cards/momiji_plain_2.svg) ![Lightning – Willow, November, Plain (1 pt)](https://hanafuda.lemme.dev/cards/yanagi_lightning.svg) ![Paulownia plain – December, Plain (1 pt)](https://hanafuda.lemme.dev/cards/kiri_plain_yellow.svg) ![Paulownia plain – December, Plain (1 pt)](https://hanafuda.lemme.dev/cards/kiri_plain_1.svg) ![Paulownia plain – December, Plain (1 pt)](https://hanafuda.lemme.dev/cards/kiri_plain_2.svg)

Any ten of the 24 plains: 1 point, and 1 more for each plain after the tenth. The Willow’s Lightning card and the Paulownia plain with the yellow band are plains like the others.

> **Rules differ**
>
> Nintendo counts the Sake cup as a plain too, so nine plains and the cup make Kasu there. In this game the cup is only an animal: nine plains and the cup make nothing yet. See [the Sake cup rule](https://hanafuda.lemme.dev/house-rules/#sake-cup).

## Dealt hands: Teshi and Kuttsuki

Two yaku come from the deal itself and are checked before anyone plays. Either one ends the round at once and scores 6: nobody has called Koi-Koi yet and 6 is below the doubling line, so nothing multiplies it. The player who had it deals the next round. If both players are dealt one, the dealer’s counts (see the [rules](https://hanafuda.lemme.dev/rules/#hand-yaku)).

### Four of a Month (Teshi)

Four pairs: your eight cards are two each of four months, here the Crane with a Pine plain, the Nightingale with a Plum plain, the Cuckoo with a Wisteria plain, and the Sake cup with a Chrysanthemum plain. A hand with four cards of one month and two pairs counts as Teshi.

> **Rules differ**
>
> Nintendo also scores both hands 6. When both players hold one, Japanese Wikipedia gives the common rule as no score for either; this game takes the dealer’s.

## How yaku add up in this game

1. **One light yaku at a time.** Gokō, Shikō, Ame Shikō and Sankō never count together.
2. **Chōfuku replaces Akatan and Aotan.**
3. **Everything else adds up, and a card may serve several yaku.** The Sake cup counts for Hanami, Tsukimi and Tane; the Boar, Deer and Butterflies for Inoshikachō and Tane; the tanzaku for Akatan, Aotan or Chōfuku and for Tan.
4. **Yaku grow.** After a Koi-Koi call you may stop again at the end of any turn in which your total rises, whether from a new yaku or from one more card for a +1 yaku.

The same captures under this game’s rule and Nintendo’s (points before doubling)

| Captured | This game | Nintendo |
| --- | --- | --- |
| Boar, Deer, Butterflies, Nightingale, Geese | Inoshikachō 7 + Tane 1 = 8 | Inoshikachō 7 |
| Pine, Plum, Cherry poem tanzaku + Wisteria and Bush Clover tanzaku | Akatan 7 + Tan 1 = 8 | Akatan 7 |
| All ten tanzaku | Chōfuku 14 + Tan 6 = 20 | Chōfuku 14 |
| Nine plains + the Sake cup | no yaku | Kasu 1 |
| Curtain, Moon, Sake cup | Hanami 5 + Tsukimi 5 = 10 | Hanami 5 + Tsukimi 5 = 10 |

Written rules differ again. Fuda Wiki’s English guide scores only the most valuable yaku of each family (Inoshikachō or Tane, not both), and Japanese Wikipedia describes the +1 for Inoshikachō, Akatan and Aotan as a rule only some players use. The [worked scoring examples](https://hanafuda.lemme.dev/scoring/#examples) take these totals through doubling and the Koi-Koi multiplier.

## Four cards to watch

- ![Rain – Willow, November, Light (20 pts)](https://hanafuda.lemme.dev/cards/yanagi_rainman.svg)

  Rain
  柳に小野道風
  yanagi ni Ono no Tōfū

- ![Sake cup – Chrysanthemum, September, Animal (10 pts)](https://hanafuda.lemme.dev/cards/kiku_sake_cup.svg)

  Sake cup
  菊に盃

- ![Lightning – Willow, November, Plain (1 pt)](https://hanafuda.lemme.dev/cards/yanagi_lightning.svg)

  Lightning
  柳のカス
  yanagi no kasu

- ![Paulownia plain – December, Plain (1 pt)](https://hanafuda.lemme.dev/cards/kiri_plain_yellow.svg)

  Paulownia plain
  桐のカス
  kiri no kasu
  Plain, despite its yellow band

* **The Rain** (yanagi ni Ono no Tōfū) is a light, but Sankō and Shikō are made without it. With it, four lights are Ame Shikō (7) and five are Gokō (10).
* **The Sake cup** (kiku ni sakazuki) counts for three yaku here: it is one of the nine animals and half of both viewing yaku. In this game it is never a plain; under Nintendo’s rules it is also one.
* **The Lightning** (yanagi no kasu) is the Willow’s plain: 1 point, one of the ten for Kasu.
* **The yellow Paulownia plain** looks different from the other two, but it is a plain.

Every card with its month and kind is on the [card list](https://hanafuda.lemme.dev/cards/), for example [the Sake cup](https://hanafuda.lemme.dev/cards/#kiku_sake_cup).

## Remembering the yaku

- **Lights count by number:** three are 5, four are 8, five are 10, and a four with the Rain drops to 7. The lights are in months 1, 3, 8, 11 and 12.
- **Most named sets are 5:** Sankō, Inoshikachō, Akatan and Aotan are three cards each, and the two Sake cup yaku are two cards each. The two complete sets are 10: all five lights (Gokō) and all six poem and blue tanzaku (Chōfuku).
- **Months for the tanzaku:** the poem strips are the first three months; the blue ones are June, September and October.
- **Inoshikachō is the name itself:** ino (boar), shika (deer), chō (butterfly), from months 7, 10 and 6.
- **Counting yaku are 5, 5 and 10:** five animals, five tanzaku, ten plains, 1 point each and +1 per card after that.
