Chess Engines

The Chess Engines application serves as a companion to a chess GUI application and is not intended for standalone use.
It lacks a graphical user interface, functioning solely as a collection of chess engines.
These engines can be employed by any Android chess application that offers a GUI for interacting with the chess engine through the OEX (Open Exchange) protocol.

The application bundles native executables for the following open source chess engines:
• Stockfish 17.1 - https://stockfishchess.org/blog/2025/stockfish-17-1/
• Stockfish 17 - https://stockfishchess.org/blog/2024/stockfish-17/
• Clover 7.0 https://github.com/lucametehau/CloverEngine

Recommended Chess GUIs:
• Analyze your Chess (free) /store/apps/details?id=com.lucian.musca.chess.analyzeyourchess&hl=en
• Analyze your Chess Pro (paid) /store/apps/details?id=com.lucian.musca.chess.analyzeyourchess.pro&hl=en

To utilize the chess engine with the aforementioned GUIs, navigate to the Engine Management Screen > Overflow Menu > Install Open Exchange Engine . From there, select the desired chess engine(s) for installation.
