While True:
Learn()

While True: Learn() (2019) is a simulation puzzle where you, as its unusual name suggests, automate systems to perform real-world tasks. To play you select and connect different elements to create logic to do things like drive a car or interpret cat language. It stands out not only for letting you program without typing but how you have to cope with randomness and probability like you do in the real world.

You play as a coder with a cat who is really good at computer programming. You set about to understand machine learning so you can eventually use visual programming to build a cat-to-human speech recognition system.

You play by solving a series of puzzles, with no coding knowledge required. You simply drag objects around your screen and connect them with lines. It's fun because there's no typing, but also because you can try, fail, optimize and try again. Once you crack the solution you press Release to watch all the data flow smoothly through your screen.

The result is a game that mirrors real-life machine learning technologies, from goofy Expert Systems to mighty Recurrent Neural Networks, capable of "predicting the future". It's an unusual way to try out what real machine-learning specialists actually do. Perhaps you'll discover a passion for (or a career in) data science.
