Sources and licenses

This page lists the origins of materials in this version of the game. It does not grant a separate license for their redistribution.

Code and development tools

The game rules, bot, board renderer and online logic were built for this project. This version runs on Cloudflare Pages and D1. The project was developed with packages listed in the project’s package.json, including Vinext, React and Drizzle. Their available license texts and notices are included in the third-party package notices; the list also includes development dependencies that are not part of every game session. Simple interface icons are styled with CSS.

Archived earlier Dragon image

An earlier illustration, no longer used for board pieces, in assets/zmaj-chess.webp was made using OpenAI image generation during this project. Use of that output is subject to applicable terms and law; see the OpenAI Europe terms of use. The image’s origin alone does not guarantee uniqueness or legal clearance of all rights.

Pieces and fonts

All board pieces, including the Dragon, use original vector SVG drawings in pieces.js, made for this project in a consistent style. The interface uses system fonts on your device. Font files are not bundled or downloaded externally.

Move analysis

Move grades come from this game’s engine, adapted to Zmaelor’s rules. The categories are approximate and do not use Chess.com’s software, data, branding or grading method.

Name and publication

The project name has not completed trademark availability clearance. This source list is not a legal guarantee or confirmation that all possible third-party rights have been resolved.
