Nobby the Aardvark is a platform game taking place over multiple consecutive levels. The player takes the role of Nobby, an aardvark who is hungry for ants. The game's plot involves Nobby trying to get to Antopia, a place where there are ants everywhere, so Nobby can eat his belly full.
In practice, most levels involve Nobby jumping from one platform to another in order to reach the exit. Various enemies inhabit the levels. Contact with an enemy is fatal to Nobby, but there are anthills scattered around the levels, and Nobby can take a quick nosh at an anthill, stuffing his cheeks full of ants. He can then spit the ants at an enemy to defeat it.
Later levels vary the gameplay by having Nobby fly in a hot air balloon or navigate a maze-like mine shaft.
