Professor Bubbles is a 5 reels and 20 pay lines video slot game. This game has humorous theme where the professor is making some funny experiments. He can turn into a frog too. As soon as I started playing this game I got a big win which was somewhere 50 x bet. I was playing on min bet though, but this was okay. There are constant wins and from time to time a big win boosts your balance. Amazing slot I must say.
There is only one special feature the free spins round. I was surprised to find out that this game does not have a unique bonus game, since all of the SkillOnNet games do. Anyhow, you get 5 free spins. They are activated with 3 or more scatter symbols. Once you activate the feature you enter the Experiment mode and I must say that I really liked the animations here. This mode features multipliers which start from x 5 in the first stage. To advance to the next level you need the frog symbol, which is the doctor in disguise I think. This can take awhile and it can be time consuming too. Sometimes I do not like this feature because it seems like there is nothing happening here and I am not a very patient person.
All in all this is a very nice game and I would recommend it to anyone. It has great graphics, the sound effects are nice and most of all it is very generous.
