The version published by Interplay and developed by Funcom of Casper plays as a top-view action-adventure game with pre-rendered graphics. The game features an alternate rendition of the film's plot (with some of its dark elements retained) spread across three acts, consisting of Casper finding tokens of friendship for Kat and Dr. Harvey, then finding the pieces for the Lazarus machine (which the Ghostly Trio had disassembled to prevent Casper from using it) and finally finding the Cellular Integrator with which to restore Dr. Harvey (which is stolen by Carrigan, leading to the final challenge), while exploring the mansion, collecting jigsaw pieces to solve puzzles for morph icons, eating food for morph points and dealing with the Ghostly Trio. Unlike other versions, other than the Ghostly Trio and Carrigan, there are no enemies. The game instead focuses mainly on solving puzzles. Once again, Casper and his uncles were reprised by their respective voice actors, while Kat and Dr. Harvey were voiced by Tanya Krievins and Blair Bess (again replacing Ricci and Pullman), with Bess providing narration for each act's introduction as well as reading out several hint parchments found throughout the game. Carrigan's voice actor remains uncredited (due to her appearing at the end and her only line being "I'll take that!").

In an odd seeming oversight; in the game, no matter what one does, the player seems to wind up with an extra red key.[2][3] Players have scoured the manor with no luck finding an extra red door. After combing through the games information, it seems there truly is no extra red door or room in which to use it. It is possible and likely that the extra red key was an oversight in the fact that it may have supposed to have been a gold key. If the player uses one of the gold key's in the wrong intended order, it softlocks the player out of the latter half of the game's secrets. It is also possible, but less likely, that it is merely a red herring.

The Game Boy Color game is a scaled-down version of the Saturn/3DO/PS game with the only puzzles and morph icons being the ones required to reach the ending and the sound and graphics are rendered for handheld.
