Geometry Friends is a 2-player cooperative puzzle-platformer game, developed within the Artificial Intelligence for People and Society (AIPS) Research Area at INESC-ID, where two players control two characters — a circle and a rectangle — with distinct characteristics, that try to collect some diamonds in a set of levels as fast as possible. The game promotes collaboration between the two players and presents challenging coordinated control of the characters in a simulated physics environment. If you’re curious, you can see two agents in action here.

Geometry Friends raises interesting problems for Artificial Intelligence (AI) agents. For example, to successfully solve a Geometry Friends level, players need to: deal with coordination at different layers, from motion control (e.g. achieving perfect timing) to level resolution (e.g. devising shared plans); deal with limited actuation situated in a simulated physics environment (with gravity and friction); solve platform (skill) based puzzles, which involves discovering the proper order to collect the diamonds and identifying the points where collaboration is needed; do all the above in real-time!

The competition is held at the International Joint Conference on Artificial Intelligence (IJCAI/ECAI’2022) and the IEEE Conference on Games (CoG’2022). You can compete in the following tracks in the IJCAI-ECAI 2022 competition: Rectangle Track GF-IJCAI-ECAI 2022, Circle Track GF-IJCAI-ECAI 2022, and Cooperation Track GF-IJCAI-ECAI 2022. For the CoG 2022 competition, you can participate in these tracks: GF-CoG 2022 – Rectangle Track, GF-CoG 2022 – Circle Track and GF-CoG 2022 – Cooperation Track. The IJCAI-ECAI 2022 competition ends on July 22, 2022, and the CoG 2022 competition ends on August 19, 2022.
