ASCII Machine is a sandbox game, in which you can build Rube Goldberg-style machines using nothing but text.
You write and run machines directly in the Editor, which colors the different components as you type them. You can then switch to Simulation mode, and see the machine spring to life in place.
The best way to try out ASCII Machine is to open the examples in a tab, and try them out directly in the Editor above. Press
Shift+Enter after you've pasted a machine to immediately see it in action.
And when you start making your own machines, make sure to keep the Quick Reference handy.
ASCII Machine is open source! You can browse its code and fork it on GitHub.
