Grand Monster Slam is a sports video game for the Amiga, Commodore 64, Atari ST, and MS-DOS.

[1] The game is based on the fictional Grand Monster Slam tournament set on the fantasy world of GhoID.

The competitors of Grand Monster Slam are drawn from staple fantasy races including trolls, orcs, ogres and imps.

Upon becoming champion of the third and final league, players are awarded the Gold Medal and the Yellow Jerkin by the King.

The standard game of Grand Monster Slam takes place on a small pitch, apparently about the same size as a tennis court.

The aim of Grand Monster Slam is to kick all one's Beloms over to the opposite side, then run across the pitch to claim victory.

When kicked across Beloms land at the back of the pitch, then move to occupy one of the six spot's on the player's line as soon as one is free.

The Beloms themselves are brown, spherical ball-like creatures with faces, which tremble as the player approaches them.

This has two consequences: the balls must be kicked with more force to get them over the wall, and the players must finish in the middle of the pitch after having gotten rid of all the Beloms in order to run across through the gap.
