Madder Scientist Slot Machine Review

A lot of us who have grown up watching Dexter’s Laboratory has at least once in our lives imagined how it is to be a scientist. The Madder Scientist slot machine allows players to relive these moments and make them come true. Betsoft has done its best in order to provide us with exactly such an experience in their 2011 casino game.
This video slot has a very peculiar theme, and it’s interesting to see how it fits into the world of free slot games. Chemistry and potion-making are so seamlessly intertwined with what would otherwise be known as special features. Players are fully involved in the process of decision-making as this game allows a great deal of interactivity. The crazy and adorable mad doc will cheer you on as you’re playing and doing sinister experiments of your own.
Players can do their science on any odd-numbered payline including 28 and 30. So, you can enjoy up to 30 lines laid out on 5 reels and 3 rows. This means that there are plenty of opportunities to make some good combinations and win money. Those looking to find out more about particular payline combinations can find that information in the View Pays tab.

How to Play Madder Scientist Slots


The interface might seem confusing at first, but this is exactly how a mad scientist’s laboratory should feel like. There are wires, levers, and buttons everywhere and we can only guess at what they do. Setting the value of your coins and placing a max bet is quite easy to do, however, you might have some trouble finding the rest of the buttons. Selecting lines and bets per line requires you to click on a beaker and a flask respectively. Moreover, you’ll find an autoplay feature in the top left corner if that is your thing.
There are no multipliers in this game, instead, you get returns based on your bet per line.


What really sets this slots game apart from many others is truly immersive special features. Mind you, there are no wild symbols that you’re probably used to in other games. Instead, there is an array of additional features that all function rather similarly to scatter symbols.

  • Click Me. This feature is represented by a lab bottle filled with green liquid, not unlike poison. It can only appear on odd-numbered reels. If it appears on all three of them, you trigger this feature. You can then choose bottles repeatedly and they will reveal different rewards. When one of them reveals the word Collect, the feature is over. Rewards include credits and free spins.
  • Wild Switches. Finding three electrical switches starts the Wild Switches feature. One of the five reels will turn into a wild reel for 5 turns. Landing more switch symbols provides one additional turn to the duration of the wild reel.
  • Bonus Landing three carrot symbols anywhere on reels triggers a bonus round. This scatter symbol takes you to a different screen where you need to make a potion of your own. Mad doc will then test your concoction on a carrot, and depending on the result, you will receive some credits.
  • Reel Respin. Didn’t like the outcome of one particular reel and you feel like that is the one you need to score big? Well, worry no more, as Madder Scientist free slots let you respin a reel of your choosing – by charging you some additional credits. This feature is available after each spin.


As was previously stated, there are 30 paylines to bet on. The lowest bet a player can make is 0.01 credits if you bet on just one payline with one coin whose value is 0.01. The coin value ranges from 0.01 to 1. Also, you can put 5 coins on a single line at most. That means that by pressing the max bet button, you stake 150 coins.
Golden payline would be filled with either the doc himself or his lovely assistant. That being said, the jackpot can include either one of them and it’s worth 75,000.

How to Win Free Slots Madder Scientist

For those interested in finding out more about payout range, or RTP as it’s more commonly known, the Madder Scientist slot sits at about 95.18%. That’s neither here nor there, so make sure to try the demo version first.
There are three very important pieces of advice that will help you make the most out of your slot machine free play session:

  1. Activate all paylines. If you don’t activate all of your paylines, you might lose out on some potential big wins.
  2. Lower the coin value. Playing a more prolonged and patient game will most likely be rewarding since special features are quite valuable.
  3. Don’t get carried away with the respin feature. You might be tempted to keep respinning until you get what you want, but that’s a good way to lose everything.

Design, Graphics, and Sounds in Madder Scientist Slot

The idea for this game is quite phenomenal, and so is the design. There are a lot more details than what you will probably perceive during your stay here. We would go as far as saying that there are maybe too many details, making the whole game feel a bit cluttered, and it’s actually much better organized on mobile devices.
Sounds are such that they spark inventiveness and creativity, and you will never tire from hearing them. On the other hand, the doc can sometimes be a pain in the neck with his comments, so decide for yourselves if you want to listen to his addendum.

Conclusion about Madder Scientist

When all is put together, it‘s quite difficult to resist the overall charm of this slot. The design will attract every wannabe scientist, and the same can be said about sounds. Features provide players with excellent opportunities to win, so if there is any conclusion to be made after reading this review, it’s that you need to try this game.
