Scalatron is a free, open-source programming game in which bots, written in Scala, compete in a virtual arena for energy and survival. You can play by yourself against the computer or organize a tournament with friends. Scalatron may be the quickest and most entertaining way to become productive in Scala. - For updates, follow @scalatron on Twitter.

Scalatron IDE and Game

To Play The Game…

…install Scalatron and work through the step-by-step tutorial to create your first bot. No prior knowledge of Scala is required and you do not need to install anything else (not even Scala).
