Appearance and Sound Effects

A madcap musical soundtrack that sounds like a cross between the Adams Family and The Munsters introduces you to the laboratory in which Manic Millions is set. Immediately, you'll spot the lab's two inhabitants standing either side of the reels. There's Dr. Cranium, an elderly scientist with huge grey eyebrows and a long beard, who is standing on a dais. Opposite the doctor is Igor – the doctor's hunchback assistant – who's as keen to serve you as he is Dr. Cranium.

The reels sit within a strange contraption consisting of bulbs, wires, and electrical circuits, and through them, you can see shelves of books, and tables filled with scientific equipment and vials of strange liquid. The paytable symbols also feature an assortment of oddities including a sinister-looking mouse, potion bottles, green blobs wearing lab glasses, Igor, Dr. Cranium, the game logo, and a Venus Fly Trap.

Bonuses and Special Features

The wild symbol is Dr. Cranium, and he can substitute for all symbols except the scatter. The Manic Millions logo is the scatter, and whenever it lands three or more times on the reel set, it triggers the Electrifying Free Spins Feature. You get ten free games, to begin with, and if three or more scatters come into view, the feature is retriggered. Plus, with each free spin, Igor can pull a lever to add as many as three extra wilds to the reels.

Manic Millions also has an Igor Wild Bonus and an Igor Scatter Bonus in which the doctor's assistant can randomly appear and add additional wilds or scatters to the screen.


Manic Millions uses five reels, three rows of symbols, and twenty-five fixed paylines, and has an average RTP (Return to Player Rate) of 95.25%.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls when played on mobile devices.
