MegaJackpots series: IGT themes linked by progressive prizes
The MegaJackpots series is IGT's progressive-jackpot franchise, built on familiar standalone slot themes connected to an additional jackpot prize layer. Wilds, scatters and free spins support the core reels in both catalog entries, but the layouts show that MegaJackpots is a framework rather than one fixed game engine.

MegaJackpots Siberian Storm uses a 5x4 screen with 720 ways, placing the jackpot structure inside a tiger-and-wilderness game. MegaJackpots Cleopatra moves to a conventional 5x3, 20-payline format and an Egyptian setting. Both carry medium volatility, while the listed RTP shifts from 92% in Siberian Storm to 91% in Cleopatra.
That contrast explains the franchise's role: IGT can retain the progressive prize proposition while changing the reel system and recognizable theme around it. Later extensions such as Elephant King MegaJackpots show how readily the label attaches to another established visual identity.
