The Rings of Kether is a single-player roleplaying gamebook written by Andrew Chapman, illustrated by Nik Spender and originally published in 1985 by Puffin Books.

Players are given a reasonable degree of freedom as they travel between various locations on the planet's surface and in orbit, and there are multiple paths to the final confrontation with the heads of the crime ring.

The major element which distinguishes this gamebook from others in the series is the heavy use of Skill rolls, which are employed several times in quick succession during the course of the book.

Unlike most Fighting Fantasy gamebooks, The Rings of Kether is unusual in that it has two ways to win the adventure.

The player can either destroy the smugglers' base or fight and kill their leader instead, a man named Blaster Babbet, to achieve ultimate victory.
