ChessGenius Exclusive is a very flat, hand-crafted wooden sensor board with a move display through 81 single-square lights and especially convenient fully automatic piece recognition.

The computer unit itself is located in a separate casing with a very generous back-lit screen offering a diverse array of display options (similar to the former Mephisto high-end models), which can also be used as a chess clock during a game.

The convenience of the fully automatic board is excellent, especially the high recognition speed and reliability. There is no need to look at the computer display during the game thanks to the brightly lit 4 LEDs per square on the board.

Python library for Integration in chess software

Dominik Schlösser

Suitable for:

  • Linux, USB, Bluetooth-LE
  • Raspberry PI, USB, Bluetooth LE
  • Windows: USB
  • MacOS: USB

The software is designed in such a way that it is easy to add new transports (e.g. other Bluetooth variants).

On the basis of our interface definitions for the chess link, Dominik Schlösser has written a library for the Python programming language, which allows a comparatively easy integration of the interface into existing chess software products. The project is currently still in its early stages, and is designed to allow chess software developers to quickly integrate the ChessLink and the Millennium exclusive checkerboard

The library supports:

  • Automatic hardware detection on USB
  • Automatic Bluetooth search
  • Train display via LEDs (optional display of 4 deductions in the analysis mode via LED sequences)
  • Interoperability with Python-chess
  • Fen Import
  • Position setup via board or Fen
  • UCI engines (tested with Stockfish and Leela chess Zero)

The library abstracts the details of the log, and provides functions such as: querying the position of the Millennium Board in fen format, passing the user’s train to the engine, Signalisi the engine’s train by LEDs

Our request: If you want to use the library or our interface, please inform us briefly about your project and also about the completion. We would like to pay tribute to successful implementations and make them available to all users at this point. Simply send a short email at

The necessary files-including the complete interface documentation from the ChessLink-can be found on GitHub.
