Kingdom of Kroz is a computer game created by Scott Miller in 1987 as Apogee Software's first game. The object of the game is to survive numerous levels of attacking monsters.

The character has gems; each time a monster touches him, he loses a gem and the monster dies. The character's main defense consists of whips, which can be used to kill monsters and destroy certain walls; however, each whip can only be used once. Some levels are generated randomly; these tend to be rather chaotic, and essentially consist of a mad dash through waves of attacking enemies to pick up valuable objects and/or escape to the stairway. A major part of the game is careful conservation of gems and whips; sometimes it is better to allow an enemy to take a gem rather than use valuable whips that will be needed to break down walls blocking the exit.

Miller, fond of including backwards words in his games, came up with the name by spelling Zork backwards.
