Professor Bubbles Slot Machine

The genius of a man, as Einstein famously said, often comes with some side effects. These side effects commonly manifest themselves through various odd habits and eccentric ideas. Einstein himself was known to be a compulsive chocolate eater, and we haven’t seen a more brilliant mind than his anywhere in the recorded history.

Until now – that is! Challenging all the scientists of the world is our very own Professor Bubbles, a well-meaning maniac who just can’t keep his hands off his lab apparatus and chemicals. The results of his mad-hat experiments are often funny, sometimes interesting and some rare times, downright dangerous. To meet the man behind the lab coat, all you have to do is log on to ‘Professor Bubbles’, a wonderful 3D mobile video slot designed and developed by SkillOnNet.

Are you ready for some cerebral action, then?

Of Frothy Beakers and Bubbling Flask

Welcome to the infamous laboratory of Professor Bubbles where impossible is a word that is never uttered. Nothing is too strange to happen here, and once you step inside, you are at the mercy of the genius chemist himself.

The very first things that struck us upon logging into Professor Bubbles was the amazing design of this slot. Every care has been taken by the developers to make it look like an actual lab, with all the apparatus, equipment and chemicals creating an authentically theme-worthy ambiance.

The graphic effects of reels turning, spins stuttering and chemical reacting are well-worth enjoying, as well. The only thing that somewhat lets users down in terms of the gameplay is the repetitive soundtrack. But barring that, Professor Bubbles leaves no stone unturned in ensuring that it makes a heck of a solid first impression, it does remind us of Frankensteins lab a little, but that may just be because we spend so much time playing Frankenslots Monster!

So, How to Crack this Equation?

Well, if you have a good deal of slotting experience, you should have no trouble whatsoever dealing with this slot (that doesn’t mean you can put up with crazy antics of Professor Bubbles – it’s just not humanly possible!). If you don’t, that’s well and fine too, because we will walk you through the gameplay in a bit.

There are five reels and 20 paylines to write your own fortune with. In what might look like a bizarre move, SkillOnNet has capped wagers per spin between 10 cent (pretty common) and $15 (what?!). It might sound more understandable if we tell you that you can wager up to three coins per line. However, the fact that almost nobody wagers less than three coins should also be taken into consideration.

In more simplified terminology, all this brouhaha means that you are allowed to wager $300 or less per spin, and that’s just about that!

Symbols of Alchemy

Professor Bubbles, for all we care, looks more like an alchemist than a real chemist, and the symbols used here somewhat back this idea. Barring a diploma roll, bubbling potions of shiny colours, heaters, sand-timers and other paraphernalia all add up to create an insanely (pun intended!) funny roster of symbols.

But more interesting than these are the special symbols of this slot. The wild – there is only one – is Professor Bubbles himself. He has the ultimate word in his lab, and thus, he can replace any regular symbols as you please.

The scatter (stacked) symbol used here is a glowing beaker. When you cross your fingers, you should wish more for the scatters, because at least three of these unlock free spins mode. In the free spins mode, you will have five graduating levels, in each of which, your winnings will be multiplied by 1x, 2x, 5x, 20x and 50x!

Another quirky feature of this slot is the bonus round, which is triggered when you have three or more bonus symbols (plasma balls) anywhere in view. It is much like the free spins mode, with the only difference being the presence of a special multiplier symbol – a frog – to compound your winnings thus far by up to 50 times. We knew that chemistry can often yield astounding results. But the kind of stuff Professor Bubbles has opened our eyes to is just the stuff of the legends.

Entertaining Bubbles

If you are looking for a slot to keep yourself entertained, without a doubt, Professor Bubbles has to be the top contender. It is quirky, quixotic and hilariously funny – and at the same time, it pulls no mean punches while paying out!

There is a wild, a scatter and a bonus round to round things up. What more could a slot fan ask for? Unless you want a more traditional game from this developer, in which case, give Magic and Wonders a whirl.
