System Requirements: Java version 1.5 or better.

Sudokumat needs no additional installation. Having Java (1.5 or better) installed the downloaded sudokumat.jar can directly be started from a command prompt in the download directory using

java -jar sudokumat.jar

Starting Sudokumat directly from your graphical user interface depends on your operating system.


Normally on Windows no further steps are needed: just double-click the downloaded jar-file to start the program.

Special case: manual creation of a short-cut

If a doubleclick on sudokumat.jar does not work, but Java is installed, then you can create a short-cut manually:

  1. Target.
    Here you must enter the full path to the Java-executable javaw.exe , completed by the parameter -jar sudokumat.jar.
    C:\Programme\Java\jre1.5.0_10\bin\javaw.exe -jar sudokumat.jar
  2. Set the working directory.
    The Windows-Assistant sets this value to the directory of the executable. But this path must point to the directory where sudokumat.jar is stored.
