CuckooChess is a sophisticated free and open-source chess engine created by Peter Österlund using the Java programming language. Distributed under the GNU General Public License, it includes a dedicated GUI and is compatible with the Universal Chess Interface protocol, allowing it to connect seamlessly with third-party GUIs such as Arena. Additionally, an Android variant exists, featuring a GUI inspired by Österlund's adaptation of Stockfish, known as DroidFish.
The engine employs the Chess Cases typeface designed by Matthieu Leschemelle. Its name is inspired by the use of Cuckoo hashing for managing its transposition table.
In the Android ecosystem, CuckooChess operates alongside Stockfish within the DroidFish chess application and is also integrated into Square Off, an AI-powered virtual reality chess game funded through Kickstarter.
By July 2018, CuckooChess achieved an ELO score of 2583 and was positioned between ranks 135 and 137 on the Computer Chess Rating List.
