Adding new games

If you consider writing your own game, you should use the NNG Github Repo as a template.

There will be an option to load and run games through the server directly by specifying a URL, but this is still in development.

To add games to this page, you should get in contact as games will need to be added manually.

Impressum

When running a game, our server collects metadata (such as IP address, browser, operating system) and the data that the user enters into the editor. The data is used to compute the Lean output and display it to the user. The information will be stored as long as the user stays on our website and will be deleted immediately afterwards. We keep logs to improve our software, but the contained data is anonymized.

We do not use cookies, but the game progress is stored in the browser as site data. The game progress is not saved on the server; if you delete your browser storage, it will be completely gone.

Our server is located in Germany.
