Equinox, known in Japan as Solstice II (ソルスティスII), is an isometric 3D action–puzzle-hybrid video game for the Super NES. It is the sequel to Solstice, a Nintendo Entertainment System game.

Glendaal moves from room to room looking for ‘tokens’ (blue orbs), twelve of which must be collected and brought to a boss area where they enable the ‘summoning’ of one of the game’s boss characters. Each of these must be defeated to enable progress to the next area. To aid the player in their quest, one projectile weapon and one magic scroll is hidden on each level for Glendaal to find. Most levels contain a number of entrances which are accessed from an over-world map, home to a sparse collection of wandering monsters. In Equinox there are eight "worlds". Each of them have own weapon, spell and boss.
