Unlock the Pro version features (multiple map levels, expand shrink a map, generate rivers/coastlines/empires quickly, add map notes, and more!) by getting a license from our store.

Windows Native Version

Download the Windows native version. Download the zip file, unzip it, and double click the .exe file to install. (Built by Excelsior JET.)

Mac OSX Version

The Mac builds allocate a set amount of memory up front.  🙁  2GB of memory you should avoid making maps of over 1000×1000 hexes.  4GB should allow for maps of up to 3000×3000 or so.  And so on. If using the child map/view level feature, it is easy for a child map to be larger than that. These numbers are guesstimates and depend on many factors.

Download the Mac OSX version with 2 GB allocated.

Download the Mac OSX version with 4 GB allocated.

Download the Mac OSX version with 6 GB allocated.

Unzip it, and double click to install.

Java Version

Download the Java version.

To run the Java version, install/update Java if needed (Note that by default, the Java download site sometimes gives you a 32-bit version of Java, which would limit you to just 1GB of memory–you need the 64-bit version), open a command line and type:

java -Xmx4G -jar worldographer.jar

You can substitute the 4G with another number of Gigabytes.  If using large hex maps that have more than 2000×2000 hexes (the size of each hex doesn’t matter) you’ll want 4 gigabytes or more, but it must be less than 3/4 of the memory on your computer. And because of the child map/multilevel map functionality, it is easy for the bottom (aka Kingdom) level to be over 2000×2000 if you use the bottom level.)

If you’re not using the standard Oracle Java (for example, TeaVM) see this thread as you may need to download additional libraries.
