Madder Scientist is a gambling machine from the Betsoft software, the company that suggests free slots of excellent quality. Here you will meet the mad scientist, his little dog and a cute assistant. The entourage is also understandable. It is a laboratory and the evidence of different experiments of this scientist. His life is a search of answers on the questions and there are a lot of questions. He has no time on usual things; he is all in science and work. From time to time there are beats and breaks in the lab, so the sounds are not surprising. This slot is similar to Jackpot Jamba.
The assistant is obedient and used to the whims of the scientist. Though, she still looks surprised since she started to work with this unusual person. It is owing to such assistants such great discoveries are made. The gamblers will have the chance to enjoy this exciting slot and maybe even win some prize.
This slot free has an excellent animation that we are able to see every time when the winning combination appears. The scientist sometimes exclaims “Excellent” and sometimes he just growls. He does so when something does not go as he wants. It can be heard how he writes something while sitting at the table and sometimes he just chuckles. In general, music and sound effects of the game are great. You will be kept entertained for long.

What is RTP?
RTP, or Return to Player, is a percentage that shows how much a slot is expected to pay back to players over a long period. It’s calculated based on millions or even billions of spins, so the percent is accurate in the long run, not in a single session.
In casino games, the ‘house edge’ is the common term representing the platform’s built-in advantage. For example, it is about 0.5% in blackjack, meaning the casino holds 0.5% of all bets over time.
RTP is the key figure for slots, working opposite the house edge and showing the potential payoff to players.
Let’s consider the example:
The Book of Dead has an RTP of 94.25%. It means that for every $100 bet, you can expect to receive $94.25 back in the long run. The remaining $5.75 is what the casino keeps.
