The sample save

Some maps come with a sample save. It comes from a real game. Press Sample save in the bar to load it.

A save fills the panels that a start date cannot fill, such as the top bar and the economy. The page reads the sample the same way that it reads your own save.

To go back to the start date, reload the page. Some maps also have a key for this. The keys of each map are below.

These maps have one: Europa Universalis IV and Europa Universalis V.

Your own save

Press Load a save, or drop the file on the map. Your browser reads the file. The page does not upload the file, and the file stays on your computer.

After a save loads, Share makes a link to the map of that save. Anybody can open the link.

Europa Universalis IV

1444 to 1792
