I bet a lot of you played this marble game when you were younger. The labyrinth marble game was developed by BRIO in Sweden in 1946. It was introduced to the United States around 1950. While many take hours to get good at it, the world record (with video proof on the site) is held by Lars-Göran Danielsson at 15.95 seconds.

But an AI called Cyberrunner, which was connected to the marble labyrinth with a camera and servos, trained for just 6 hours and managed to finish with a new world record of 14.48 seconds – almost 10% faster than the current record. During it’s learning, it even discovered cheats to cut the maze (though the new record was set without using any of those illegal shortcuts).

Read more about Cyberrunner at their project site, read the technical paper, and the source/hardware are about to be open-sourced. Or you can watch it below:
