Pandemonium! is a 1996 platform video game developed by Toys for Bob and published by Crystal Dynamics for the Sega Saturn. Pandemonium! features Fargus, a joker, and Nikki, a sorceress, who unwittingly casts a spell that destroys the town. The goal of the game is to reach the Wishing Engine, where they can wish the town back to normal. For each level, the player can choose which character to be. Each has a special move – Fargus can deliver a special spinning attack, and Nikki can double jump. The game consists of a great variety of unique gameplay objects, such as watermelons, clouds, spider webs and logs.

Pandemonium! employs 2.5D gameplay; while the game renders polygons in a typical 3D fashion, gameplay is 2D. The area of gameplay is as a two-dimensional surface twisting and bending in a three-dimensional world. Occasionally, this surface will overlap itself. There are segments where the path branches, allowing the player to choose their course.

Enemies are generally defeated through the usual platform jumping method of bouncing on the enemy's head. There are power-ups located in each level, with varying effects. One is a freeze ray which turns enemies into ice, while another is a shrink ray which reduces the size of enemies to the point where the player character can step on them.
