# Credits and licences

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

Last updated 27 September 2026

The hanafuda card pictures on this site and in the game are by Louie Mantia and すけじょ, with the card back and three revised faces by Spenĉjo, all from Wikimedia Commons under CC BY-SA 4.0. You may reuse and adapt them, commercially too, as long as you credit the authors, link the licence, say what you changed and share adapted pictures under the same licence. This page lists every file with its original, then the app icon, the historical pictures, sounds, fonts and software the game uses, and a note about this site.

## Card art

The 48 card faces and the card back are SVG drawings from the set [“SVG Hanafuda with traditional colors (black border)”](https://commons.wikimedia.org/wiki/Category:SVG_Hanafuda_with_traditional_colors_%28black_border%29) on Wikimedia Commons. The faces are すけじょ’s traditional-colour version of Louie Mantia’s hanafuda cards, and Commons credits each of them to both. Spenĉjo drew the card back and uploaded the current revision of three faces. Every file is licensed [CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/) by its authors, and the copies used here stay under that licence. It covers the pictures only, not the game’s code.

Who is credited for the 49 files

| Files | Authors | Licence |
| --- | --- | --- |
| 45 card faces | Louie Mantia and すけじょ | CC BY-SA 4.0 |
| 3 card faces: the Bridge, the Maple blue tanzaku and the Lightning | Louie Mantia, すけじょ and Spenĉjo | CC BY-SA 4.0 |
| The card back | Spenĉjo | CC BY-SA 4.0 |

### What was changed

The same changes were made to every file, and none of them alters the drawing:

- Minified with [SVGO](https://github.com/svg/svgo) 4.1.0 (default preset, multipass).
- `width` and `height` attributes added, equal to the drawing’s own viewBox (976 × 1600), so that every browser can draw the file into a canvas. The pictures were not resized or cropped.
- A comment added at the top of each file, naming the original, its authors, its Commons page and the licence.
- Each file renamed after the card it shows, as the game names it (`matsu_crane.svg` is the Crane).

Rendered before and after, the files differ only in a few anti-aliased edge pixels. A plain-text copy of this list travels with the pictures as [cards/CREDITS.md](https://hanafuda.lemme.dev/cards/CREDITS.md). The [list of all 48 cards](https://hanafuda.lemme.dev/cards/) shows the same pictures month by month.

### Faces by Louie Mantia and すけじょ

### Faces revised by Spenĉjo

Three faces are used in the revision Spenĉjo uploaded, so they are credited to Louie Mantia, すけじょ and Spenĉjo, CC BY-SA 4.0. The upload notes on Commons say what was changed:

- Bridge (4 January 2026): “Added orange, for a more traditional and representative color scheme.”
- Maple blue tanzaku (4 January 2026): “Changed yellow to dark gray, for a more traditional and representative color scheme.”
- Lightning (28 December 2024): “Updated card art to a more traditional design, based on Louie Mantia’s original SVG and a public domain scan”.

## Reusing the card pictures

You can download any card from this site (the file names above link to the files) or take the originals from Wikimedia Commons. CC BY-SA 4.0 lets you copy, share and adapt them for any purpose, commercial use included, on these conditions:

1. **Credit the authors.** Louie Mantia and すけじょ for the faces; Spenĉjo for the back and, with them, for the three revised faces.
2. **Link the licence:** [creativecommons.org/licenses/by-sa/4.0](https://creativecommons.org/licenses/by-sa/4.0/).
3. **Say what you changed,** and that the files you took from here were minified.
4. **Share alike.** A picture you make from them, such as a recoloured card or a new drawing traced over one, must be licensed CC BY-SA 4.0 (or a compatible licence). This applies to the pictures, not to everything they appear next to: your own text or your game’s code can keep their own licence.
5. **Add no restrictions.** Do not add terms or technical measures that stop others from using the pictures under the licence.

## Images made from the card art

Some images made for this site include card pictures, for example the preview images shown when a page is shared on social media or in a chat. They are adaptations of the card art, so they are licensed CC BY-SA 4.0 too, with the same credit to Louie Mantia, すけじょ and Spenĉjo. The same applies to any screenshot of the game that shows the cards.

![The logo: a hanafuda card emoji with a gold edge](https://hanafuda.lemme.dev/logo-mark.svg) ![The app icon: the same card on a black lacquer background](https://hanafuda.lemme.dev/icons/icon-192.png)

The app icon, the favicon, the header logo and the startup images all show the 🎴 “flower playing cards” emoji from [Twemoji](https://github.com/jdecked/twemoji) (v17.0.3), © 2019 Twitter, Inc and other contributors, licensed [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/). The version used is the file `1f3b4.svg` from jdecked/twemoji, the maintained continuation of Twitter’s Twemoji; the drawing dates from Twitter’s releases.

**Changes:** a gold edge was drawn around the card; for the app icons the card was scaled and placed on a lacquer-black background; the monochrome icon is reduced to a one-colour silhouette; everything was resized and rasterised to PNG and ICO. The adapted icons are licensed CC BY 4.0 as well. Twitter and the Twemoji maintainers do not endorse this game.

The four app shortcut icons (practice, play with a friend, rules, yaku) each draw one [Lucide](https://lucide.dev) icon (bot, users, book-open, sparkles; ISC licence) in white on the same background.

## Historical pictures

The [history of hanafuda](https://hanafuda.lemme.dev/history/) is illustrated with old cards photographed or scanned by others. Each is credited here as its Wikimedia Commons page gives it.

## Sound effects

Every sound in the game is a cue from the “Zen” pack of [UI SFX](https://uisfx.com/#sound-library) by Yuki Capital, dedicated to the public domain under [CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/). No sound file is downloaded: the UI SFX runtime (MIT licence) synthesises each cue in the browser. Neither the sounds nor the runtime were changed. Both licences are reproduced in full in [sounds/CREDITS.md](https://hanafuda.lemme.dev/sounds/CREDITS.md).

## Fonts

The text is set in [Plus Jakarta Sans](https://fonts.google.com/specimen/Plus+Jakarta+Sans), and Japanese names such as the cards’ names in [Noto Serif JP](https://fonts.google.com/noto/specimen/Noto+Serif+JP). Both are licensed under the SIL Open Font License 1.1 and are loaded from Google Fonts, which the [privacy policy](https://hanafuda.lemme.dev/privacy/#services) explains.

## Software and libraries

The game is built with the software below. All of it is open source except GSAP, which is free to use under its own “no charge” licence; the avatar drawings and the sound pack are public-domain assets. The licences are the ones each package declares in its own files, for the versions the game uses.

## About this site

Te-awase Koi-Koi Online (手合わせ: a match between two players) is a free version of Koi-Koi, the two-player hanafuda game (also written “koi koi” or “koikoi”), that runs in the browser: online against a friend after signing in with Google or Apple, or practice against the computer with no account needed. The guides on this site explain its [rules](https://hanafuda.lemme.dev/rules/), [yaku](https://hanafuda.lemme.dev/yaku/) and scoring, the cards and their history, in English and in Japanese; each language has its own text.

- **Where the rules come from.** The guides describe the rules exactly as this game plays them, and mark every point where they differ from Nintendo’s published rules and common Japanese house rules; the [house rules](https://hanafuda.lemme.dev/house-rules/#nintendo) page compares them side by side. Each guide lists the sources it used.
- **Independent.** This site is not affiliated with Nintendo or any card maker.
- **Last updated** on 26 September 2026.
- **Your data.** What the game stores, and why, is in the [privacy policy](https://hanafuda.lemme.dev/privacy/). Common questions are answered in the [FAQ](https://hanafuda.lemme.dev/faq/).
