How this game was made

Pocket Pawns is honest about its tools, here and in the game’s own credit roll. Nothing is generated live while you play — everything that ships was made, reviewed and placed by hand before release. The list below mirrors the game’s own credit roll, and the two are kept in step on purpose.

• Design, code & writing — Claude (Anthropic), with Pocket Pawn Games.
• Chess piece art — ChatGPT (OpenAI), 2024.
• Board art — Gemini (Google).
• World & environment art — two separate sources: assets created with Nano Banana Pro, and free-to-use CC0 packs found online. Neither was painted over the other.
• Character sprites — Claude (Anthropic); pixel art drawn in code, not generated.
• In-world art & interface — Claude (Anthropic), drawn to canvas.
• The 3D worlds — Claude (Anthropic), modelled in code.
• Animation — Claude (Anthropic).
• Sound effects — Claude (Anthropic), synthesised in code.
• Music — Suno. The 76-track score only; the sound effects above are a separate thing and are built in code.

Ground textures and UI frames

Some of the game’s terrain and interface source material comes from CC0 public-domain packs, Screaming Brain Studios’ among them. CC0 asks for no attribution at all; it is given here anyway.

This website

Built with Astro. No cookies, no analytics, no trackers. Its type is Literata and Bricolage Grotesque, both under the SIL Open Font License 1.1 and self-hosted here, so the page never calls out to a font service. (The game’s own type is a different set — Inter, Fraunces and Bangers.)

The playable position on the front page is a real entry from the game’s own capture bank. A mate in one is judged by chess.js; the deeper positions are judged by the Stockfish build above, running in your browser and reaching nothing outside it.
