Professor BigWin Slot Review
Enter the lab of a mad scientist with the Professor BigWin online slot. This bungling boffin appears alongside test tubes and microscopes on the five reels and four rows. A plasma ball wild acts as others, and the exciting discoveries include synchronized reels, symbol replacements, plus free games with these features on every spin.

Start Your Research
Developed by Atomic Slot Lab, the Professor BigWin slot machine features playing card emblems alongside the various bits and pieces of his lab. The cartoon Professor has the wild white hair, and crazed look in his eyes that we expect from a mad scientist. He’s on the reels, and also standing to the side, ready to pull a lever and trigger the extra features.
Join him across desktop platforms and at the best online casinos you can play on mobiles.
Unlock the Laboratory
You can experiment and play Professor BigWin for free right here. Then unleash the symbols for real money stakes of 0.40 to 120.00 per spin, or 0.01 to 4.00 on each of the 40 paylines that run from the left reel. Here’s what each pays as a multiple of the line stake –

A Great Concoction of Features
It’s an online slot with bonus features including a plasma ball wild symbol that stands in for others if needed. A Mystery Replacement feature changes random symbols into more examples of a single type on each spin, making it a little easier to get a win.
Play the Professor BigWin slot online and the animated character to the side of the reels can spring into action at any time. He pulls a lever to trigger a Replicating Reels feature, where a random number of reels hold matching symbols. The electric transformer symbol in two places also awards this feature.
Full stacks of Free Games symbols on at least two reels are enough to trigger seven free spins of the Professor BigWin online slot reels. Replicating Reels land on every bonus spin, and a High Voltage mode adds extra free games to the total.
Trust the Science
Similar games include the Mad Scientist online slot from Betsoft and the Dr Watts Up slot machine by Microgaming.
A Game With Real Chemistry
The cartoon scientist, puffs of green smoke, purple electricity, and other fun animations bring this laboratory to life. The gameplay and features are also pretty lively, with symbol transformations, synched reels, and free spins among the results.
See if you can concoct the biggest wins as you play the Professor BigWin slot machine at our favorite desktop and mobile casinos.
