Jev beat Super Mario Bros. Every moment, the simulator returns structured data of the game's current state, such as Mario's position, nearby enemies, and terrain, and simulates possible actions like jumping and running. Jev returns a probability distribution for the next chosen action based on its criteria of staying alive, which the program then executes. It passed the first level with only 1 death.
