The graphics on this slot are simply top class and from the minute the game loads you’ll be irresistibly drawn into the laboratory with bubbling potions and spooky looking machinery. But never fear as the insane scientist is always on hand to help, aided by the trusted Igor. But will you be able to come up with your own winning formula? Here’s a review of Manic Millions by NextGen with all the info you need to play.

Raving Reels

There’s insanity in every direction in Manic Millions but before you join in with the craziness you’ll need to decide how you want to bet. Five reels and 25 fixed paylines form the basis of this game. You won’t be able to change the number of paylines in play, so all 25 will be active with every spin. You can, however, set the value per spin even if the controls aren’t immediately obvious. Unlike other games, the full information is hidden and appears when you hover over the relevant buttons at the base of the screen.

The coins are the icons for the spin value and as you click on the small arrows a box with the betting sums will magically appear. Your entry level is just 0.01 per payline but can be increased up to 10.00. This amount is per active payline, so provides a total min bet of 0.25 and a total max bet of 250.00. The variance on this slot is medium to high and there’s an RTP of 95.25%.

Potions Mean Prizes

With so many concoctions bubbling away in the lab, it’s little surprise that there’s far more to this game than simply matching up the basic symbols. The mad doctor and Igor are benevolent in their madness, and offer a range of extras on the reels to help bump up your winnings. The scientist himself is the wild on the reels and can help you to line up matches far more easily. There’s humorous little animated sequences when he makes a winning line so you’ll be able to see instantly if you’ve racked up a prize. There’s also the scatter symbol and if you land three of these anywhere you’ll unlock the Electrifying Free Games.

In this bonus feature you’ll receive 10 free spins, which will take place immediately. However, it’s Igor himself who is the biggest help as he’s willing to hand out a whole heap of prizes in both the free spins and the base game. The Igor Wild Bonus is triggered randomly and allows Igor to lumber on and hand out up to 3 more wilds in the free spins phase. In the base game the same bonus provides the opportunity for one more wild. There’s also the Igor Scatter Bonus, also triggered randomly. Here Igor will add scatters to reels 2, 3 and 4. The Electrifying Free Games can be retriggered during play.

Lab Hopping

If you’re enjoyed your time in this crazy laboratory you could always hop over to another mad scientist’s domain and find out how they compared. And there’s none better than Freaky Frankenstein, another crazed doctor who has taken it upon himself to create his own devoted companion. More spectacular 3D graphics, and with a slightly more forbidding look than the dopey Igor, Freaky Frankenstein from Nucleus Gaming offers a real treat. Five reels and 20 paylines mean the two titles are very similar and with a gamble feature, free spins and a bonus round too there’s lots of potential winnings packed in here, too.

Crazy Creations

Manic Millions by NextGen is an online video slot which offers superb graphics which really bring the game to life. The Igor bonuses provide some extra value but it’s slightly disappointing that there’s not a full bonus round included. The range of betting is wide so accommodates both low and high rollers and this makes the game a great play for all levels of experience.
