Cute Chess

Build Status AppVeyor Status Coverity Scan Build Status

Cute Chess is a graphical user interface, command-line interface and a library for playing chess. Cute Chess is written in C++ using the Qt framework.


Binaries for both the GUI and the cutechess-cli command-line interface are available here


Cute Chess requires Qt 5.7 or greater, a compiler with C++11 support and qmake.

In the simplest case you only have to issue:

$ qmake
$ make

If you are using the Visual C++ compiler replace make with nmake.

Documentation is available as Unix manual pages in the docs/ directory. API documentation can be built by issuing make doc-api (requires Doxygen).


The cutechess-cli program is run from the command line to play games between chess engines. For example to play ten games between two Sloppy engines (assuming sloppy is in PATH) with a time control of 40 moves in 60 seconds:

$ cutechess-cli -engine cmd=sloppy -engine cmd=sloppy -each proto=xboard tc=40/60 -rounds 10

See cutechess-cli -help for descriptions of the supported options or manuals for full documentation.


Get involved

To help with translations, add a line after the last line of, in the following format:

TRANSLATIONS += translations/cutechess_[language_code].ts

Then generate the translation file by running the command:

$ lupdate

There will be a new file pending for translation. Edit with Qt Linguist:

$ linguist translations/cutechess_[language_code].ts

If new strings are added in source code, run lupdate to update corresponding .ts files.

Compiling translations

After finishing translation, generate the binary file with the command:

$ lrelease translations/cutechess_[language_code].ts

There will be the final .qm file for GUI application. Place the GUI executable under the same path of translations directory.
