Puzzlebyrinth Sanpo

Design

A title font for the site's weekly puzzle "Sanpo" (trace a one-stroke path through a digit grid — diagonals allowed — to fill blank equations). Each letter is drawn as a traced path: thin lines join nodes over a faint grid of digit dots, with a solid dot marking the start and a ring marking the end.

The path skeleton builds on Maze's polylines. Set in Latin "Sanpo" throughout.

• Regular: One-stroke path + nodes + digit grid. For titles and headings.

License

Released under the Puzzlebyrinth Font License 1.0 — free, commercial use allowed, attribution required. By downloading or using the font you agree to its terms. In short (the full license text, also bundled in the ZIP, prevails over this summary):

You can

• Use the font free of charge, personally or commercially (logos, print, video, streaming, games).
• Embed it as a web font and bundle it with apps and games.
• Modify it and redistribute original or modified versions.

Conditions (required)

• Attribution: when you publish or distribute work that uses the font, credit “Font: Puzzlebyrinth Sanpo (puzzlebyrinth.com)” (or an equivalent) in a reasonable place — credits, video description, site footer, colophon, etc. Private, unpublished use needs no attribution.
• When redistributing the font files, include the license text (LICENSE.txt) unchanged.
• Modified versions may not use the original font name — pick a different name and keep this license.

You cannot

• Sell the font files by themselves (bundling with software or games is fine).

The font is provided as-is, without warranty. It does not cover Japanese (kana/kanji), so specify a fallback font when using it on the web.

Usage (CSS)

@font-face {
  font-family: "Puzzlebyrinth Sanpo";
  src: url("/fonts/PuzzlebyrinthSanpo-Regular.woff2") format("woff2");
  font-display: swap;
}
h1, .score {
  font-family: "Puzzlebyrinth Sanpo", sans-serif;
}

Remember to include the attribution “Font: Puzzlebyrinth Sanpo (puzzlebyrinth.com)” when you publish your work — it is required by the license. Questions and bug reports are welcome via the contact form.
