Jackpot Lab

Jackpot Lab combines an inventor's workshop with Free Spins and a sixth Bonus Reel. Three Scatters award eight Free Spins, and more qualifying symbols can retrigger the round. Separately, three Bonus symbols activate the extra reel. Its result may be a cash award or one of four fixed jackpots: Mini, Minor, Major or Grand. The Bonus Reel moves slowly above the normal five-reel game, giving the jackpot route its own visible place. Players can tell which symbols lead to additional spins and which start the prize reveal, even when both routes appear in one session.
