Manic Millions by NextGen Gaming is a 5-reel, 3-row slot with 25 fixed paylines and a 95.25% RTP. The game uses a mad-science laboratory theme, with cartoon symbols including flasks, lab characters, slime creatures, and a WILD symbol that can substitute for most regular icons.
The bonus structure centres on Scatter symbols and the Electrifying Free Games feature. Three or more Scatters award 10 free spins, while Igor may add Wilds during base play and can place extra Wilds in the bonus round. A separate Scatter bonus can also add Scatters to reels 2, 3, and 4 after a spin.
This demo version allows players to play for free and practice before playing for real money. The layout includes clear payline-based wins, bonus information panels, and a standard slot paytable for matching combinations.
