Gameplay mechanics in Jazz are very similar to Zool's, with the exception of not being able to destroy the enemies by simply jumping at them (which was not added until the second game).
Items that the player can pick up usually resemble food, computer hardware components or other familiar shapes, and give 100 score points each.
There are also several beneficial pick-ups in the game: a "force shield" that protects Jazz from one or four hits, a Hip Hop that shoots enemies, a hoverboard that allows flight, rapid fire/super jump bonuses, a temporary "speed-up" and invincibility, as well as extra lives.
Weapons also vary in numbers and consistency and include (besides the Blaster) Bouncer, Toaster, RF Missile, and TNT sets.
An evil mastermind tortoise named Devan Shell begins conquering planets, suppressing any native confrontation.
Enraged by his loss, Devan decides to kidnap Carrotus princess Eva Earlong and hide her on a distant airbase of unknown location to use as ransom.
In response, the king chooses to send Carrotus' hero Jazz Jackrabbit, a green hare with a blue LFG-2000 gun, to various planets conquered by Devan that might contain clues to the location of Eva's imprisonment.
As Jazz travels through different worlds, he gains new weapons and meets new enemies in his pursuit to rescue the princess and save Carrotus from Devan Shell and his army of Turtle Terrorists.
A shareware Christmas edition titled Jazz Jackrabbit: Holiday Hare 1994 was released on December 15, 1994, with a special 3-level holiday-themed episode.
The game did not manage to reach the popularity of Sonic, but did acquire a sizable audience due to its fast-paced gameplay and advanced graphics.
