Odin Sphere is a two-dimensional (2D) side-scrolling action role-playing game where the player takes control of five different characters across six playable scenarios. Areas within levels are circular stages allowing movement left or right with exits leading to other areas; the main goal in each area is to eliminate all enemies and proceed to the next area. Combat—which uses a beat em up-style battle system—takes place within these areas, and revolves around the player character using a combination of physical attacks and Psypher skills, skills tied to each character's magical weapon. Combination attacks are triggered by attacking enemies continuously. Jumping can be used to reach airborne enemies within stages. At the end of each battle, grades are awarded based on the battle time, damage taken from enemies, and the amount of damage dealt. The amount of in-game currency the player receives as a reward after each battle depends on the battle grade.
