The Missing Ring is a role-playing video game written by Terry Romine for the Apple II and published in 1982 by Datamost.

[1] The Missing Ring is a fantasy adventure with a similar premise to the Dungeons & Dragons role-playing game series: a band of adventurers, which may include humans, elves, dwarves or wizards, enters an enchanted palace to seek treasure and slay enemies.

Characters appear as small, white silhouettes, and move through rooms rendered as perspective line drawings.

A header at the top of the screen indicates the room being shown, and a footer gives details about the active character, including his level, health and experience.

Two complete sets of controls are arranged at either end of the keyboard, allowing two people to play simultaneously without having to trade off.
