"Orbicle.io" is a game where players control orbs on a toroidal map. This means the map repeats infinitely in all directions. The gameplay involves orbs interacting based on their size:

- If a small orb touches a larger orb that is three times its size or larger, it absorbs mass from the larger orb.
- If the larger orb is less than three times the size of the small orb, the smaller orb loses mass to the larger one.
