The Obstacle Tower is a procedurally generated environment consisting of an endless number of floors to be solved by a learning agent. It is designed to be a new benchmark for learning agents specifically in the areas of computer vision, locomotion skills, high-level planning, and generalization. The Obstacle Tower Challenge combines platforming-style gameplay with puzzles and planning problems, all in a tower with an endless number of floors for agents to learn to solve. Critically, the floors become progressively more difficult as the agent progresses. To learn more about the Obstacle Tower, read our full paper on the environment here.


Your mission in the Obstacle Tower Challenge is to create an agent that can successfully navigate the Obstacle Tower environments we have created.

Up to a maximum of 4 people can enter the Obstacle Tower Challenge as a team. You must be at least 18 years of age and a resident of certain countries to enter the Challenge. For more eligibility criteria, please read the Official Rules (linked below).


To create an Entry clone the Challenge Starter Kit and then develop code to create and train a model that is able to interact with the Obstacle Tower Environment (the agent). The goal is to create an agent that can advance further than everyone else’s. There are two Rounds, the first with a 25 level environment and the second with 100 levels!

Evaluation Criteria

In each round, we will run each agent through the applicable Obstacle Tower environment and evaluate how the agent does across 5 randomly generated seeds and then the entries will be ranked, from most to least, in accordance to the average of the number of levels reached in each seed. Ties will be broken on the basis of the average number of doors and keys collected by the agent across the aforementioned 5 seeds. In order to move onto Round 2, an Agent must be able to reach an average score of 5 in Round 1. If fewer than 20 are able to do so in Round 1, the average level requirement will be 4.


For the full requirements, please carefully read the Official Rules, available here.
