Acknowledgements

Pibono is built on a lot of generous work by other people. Here is who and what we are grateful to — the open-source code, word lists, and typefaces that make the games possible.

Open-source code

  • Stockfish — our Chess opponent is Stockfish.js, a WebAssembly build of the Stockfish engine, distributed under the GNU General Public License v3. © the Stockfish authors. stockfishchess.org — the vendored copy and its full licence live alongside the code.
