At its heart, Gyron is a 3D maze game. The player controls a vehicle called the Hedroid, which can hover up and down the trenches in the maze.
The idea is to reach a certain goal within the maze. The Atrium is really a training maze, made easier to allow the player to get used to the controls and the general strategies required to win. The conclusion of The Atrium is locating the entrance to the second, inner maze – The Necropolis, which is much harder and requires a great deal of thought. The ultimate goal is to reach the hidden Place of Wisdom.
Of course, floating through trenches in the maze would be boring if there weren't obstacles and destructive forces to get in the player's way. Giant balls patrol the maze in set patterns, and they are deadly if the Hedroid collides with them. Towers also watch over the maze, and if they are facing in the right direction, they can blast the Hedroid.
Thankfully, the Hedroid comes equipped with a short-range radar as well as a weapon that can be used against Towers. Single towers have a blind spot, so the Hedroid can sneak past without being detected. The player can also use the giant balls as cover and get further into the maze without being shot at. Shooting a tower from behind is the only way to destroy them, but their destruction can sometimes create a new tower or rotate another tower in a different direction, thus making the maze even harder to complete!
