General Overview

Professor Bubbles is a 20-payline SkillOnNet powered video slot that’s centred on a mad professor who’s really into different kinds of experiments, which at some point go out of control and turn him into a short-bodied and tailless animal. Technically, Professor Bubbles is very similar to SkillOnNet’s hit Hot Wheels, but it’s not a direct clone as they are slightly different. This also means that one of them isn’t better than the other as both of them offer something that the other one doesn’t have. Better yet, you can compare both of them personally without risk at one of the featured casinos, such as EUcasino and Mega Casino.

Features and Bets

Just like many other SkillOnNet slot releases, Professor Bubbles is low variance with an average theoretical return to player. Similarly to the rest of their 3D-rendered games, this game isn’t without an action character doing funny things beside the reels. The background music is balanced and suspending, although it could’ve been a little more energetic.

When it comes to betting then Professor Bubbles is fairly flexible and allows placing up to three coins on each active line that can be valued .01, .02, .05, .10, .25, .50, 1, 2 and 5 credits each. On the other hand, all 20 win-lines are fixed and cannot be adjusted at all.

Symbols and Bonuses

Professor Bubbles symbols are all about the laboratory. While the highest paying symbol in Hot Wheels is 500 coins, Professor Bubbles’s lab equipment pays up to 600 coins. On the other hand, the biker themed counterpart pays better for weaker combos. In the base game the professor is Wild, but turns into a frog whenever the player wins over two scattered beakers anywhere on the reels. For that, 5 Free Spins with a special 4-level multiplier meter become active. The aim is very simple and straightforward: collect as many beakers as you can and progress to the next level, where winnings are multiplied by a much higher value and multiplier goes from x5 to x10, x20 and up to x50! Note that winnings are magnified only with the Frog symbol and not on their own. The biggest difference between Professor Bubbles and Hot Wheels, interestingly, is that the multiplier meter in the latter has a twice as high maximum as the one in Professor Bubbles but much lower values in the first three levels.


Professor Bubbles is a 5-reel, 20 payline, SkillOnNet non progressive video slot machine. Professor Bubbles Slot comes with a wild symbol, scatter symbol, multiplier, free spins and more.
