Madder Scientist Slot Betsoft

Madder Scientist is a 30-payline video slot operating on the Betsoft software platform. The Switch symbol is wild and the scatter Bonus symbol is the Carrot. Players can try the slot on this page for free or visit any of the Betsoft casinos found in the listings to play the game for real money.

Prior to joining the scientist in his secret quarters, players need to decide on their bet. The “Choose Coin” button alters the coin size, which ranges from 0.02 to 1. “Select Lines” selects the number of paylines played, while “Bet Per Line” modifies the number of coins bet. “Spin” turns the reels, “Max Bet Spin” spins them at the highest bet and “Au­top­lay­” lets players play the game for a preset number of times without being interrupted.

After each spin, players can decide to re-spin any of the 5 reels for an additional chance of winning. The re-spins cost additional credits.

3 Beaker symbols emerging on reels 1, 3 and 5 activate the Click Me feature. Players then need to select a beaker in order to uncover their prize. They can continue to select beakers until the word “Co­lle­ct” appears.

When 3 Switch symbols appear on the reels, the Wild Switches are triggered. In this feature, 1 of the 5 reels will be chosen arbitrarily to turn wild for a preset number of spins.

The Bonus round starts when 3 or more Carrot icons appear on the reels. During the Bonus round, players need to help the scientist create a new concoction which he will then test on the carrot.

What can be better than a mad scientist? A madder scientist of course. So, did the first mad scientist gave me any good results to make me happy? Nope, that mad scientist only got me mad as well! Okay, so perhaps this madder scientist can give better results and make me happier? What, are you nuts? It only made me madder! Hahaha. Well, that sums up what this sequel game did to me. I was hoping for better wins, none appeared. I was hoping for better win potentials, none could be delivered. In fact, the paytable became even lower! What the argh!

From 20 paylines, this madder game now plays with 30 paylines, with the same selectable lines to play, but some things got thrown out the blardy window! What things? Well, the Wild symbol is one of them. There isn't any Wild symbol appearing on the reels, not until all 3 of the Switch Scatter symbols appear anywhere on the reels, to turn one random reel into a full Wild Reel for a random number of next spins. Nope, the spins are not free spins! Each spin still eats your credits, like it or not! That Wild Reel is there only to give additional winning chances, that's all. What the argh! The Beaker is the Bonus symbol, appearing only on reels 1, 3 and 5, and just like that Switch symbol, this Beaker symbol is just as dumb! Getting all 3 symbols on the reels trigger a 'Click Me' feature game. Another "argh" from me. Keep picking on one Beaker symbol at a time to win an instant cash prize, but getting a 'Collect' icon ends the game.

The Carrot is yet another dumb Bonus symbol, and getting 3 or more of them anywhere on the reels trigger another 'Pick Me' feature game. Argh! This time, pick 2 bottles out of 6 to mix a concoction to turn the carrot into gold. A reward is given for turning the carrot into Bronze, Silver or Gold. I managed to turn it into gold in one of my sessions, but that gold paid me only 16x my bet amount. Hmm, so much for getting gold that! As for the other symbols, the Scientist pays 500 credits, the Lady Assistant also pays 500 credits, the Rabbit pays 400 credits, and the rest pay from 300 to 40 credits, all for getting 5 of each kind. An even lower paytable than that of Mad Scientist game.

In the base game, after each spin, each individual reel can be respun for another try to make a win, or a better win, but each respin on each reel has a cost to be paid. When I was playing this game for the first time, 1 or 2 years ago, I was excited at the possibility of respinning any reel that I want to try and make a win. I certainly gave it many tries, getting some wins, but losing a lot lot more. If you're not careful, you may even lose all of your credits in record time! This Respin feature is a real killer, to be very honest, even though a few good nice wins and some feature games can be won at the right times. Only use this feature with extreme caution!


Well, this newer Madder Scientist game certainly came with some changes from the original, but the way I see it, those changes made no difference at all to the game's winning potentials. In fact, the highest symbol value had been cut by half, further reducing the chances for decent wins. Remember, I said decent wins, not good wins. My best win after several sessions on this game, was and still is, only 18x my bet amount. Can you believe that? Sheesh!

Madder Scientist is a 5 reel and 30 payline slot from Betsoft software and although I had tried it before, only recently I've been playing it a lot. This slot has scientist theme and I have to say both the design and bonus rounds are quite expected and this slot reminded me Microgaming's Dr. Watts up slot a little.

Although this game doesn't surprise me with it's looks or bonuses, I really enjoy playing it. But I have to say this game can be a money eater, because the minimum bets per spin are 0.60€ and because of re-spin buying option. I have to say this is one of the first games I've actually experienced paying for re-spinning a wheel. And from my experience you have to be careful with that because sometimes you can lose a lot more, paying for multiple respins until you get a bonus round, than you will actually win on that bonus. Also, to be able to get a re-spin you can't play on autoplay, that's why before I didn't even pay attention and didn't know there was this re-spin option.

But I was quite disappointed that this game doesn't have a standard free spins option, it has only two bonus rounds, one of which can contain a couple of free spins. And although I like re- spin option, the last time I played this game, I got so persuaded to get the bonus round, that I re-spinned until my balance was gone, and sometimes the respins are very costly.

From three bonuses they have, only two are completely free. One bonus is wild reel bonus, then one reel turns wild for a couple of spins, but the spins themselves aren't free. The other two are pick me bonuses. I think my favorite is the main bonus, where you need to mix chemicals to see your winnings. For me it is the easiest one to trigger, however, I never know what to expect. There have been times when I've won 40x bet on it, but mostly it gives around 10x bet. Wild reel is good, but most of the time I get it on the very last reel and then there's not much point of it.

What I like about this game is that it's exciting. Many features that aren't too hard to trigger can help to wager a bonus with this slot. Graphics are good and I never get bored. And although sometimes it can be not worth to use respin option, because it is expensive, I like the fact there is such option and it can help to get bonus round.


There are two things I don't like about this game. First of all, because of the minimum bets, and if you pay for respins, this game can be a money eater. Sometimes I've been using a few respins and lost over 10€ not even noticing it. Also I don't like that there are no regular free spins, I think if game has so many features, one of them should be free spins, because free spins is a bonus which can surprise with large winnings, while I don't think it's possible with the bonus rounds this game already has. That being said, I haven't reached around 100x bet winnings and I think it's a hard thing to do.

By playing this slot machine you will not have a reason to be angry, even though the title says nervous scientist who mixes different chemicals to you brought as many winning line of payment and therefore the direct gains. This creative slot good fit with what is Betsoft recent years to build. Now finally we have a slot where it saying "luck is unpredictable," really has its true meaning. If you have previously socialized with Betsoft slots you probably know that this is a continuation of the mega popular slot machine Mad Scientist.

This mad scientist offers you a range of tempting opportunities to work together in a laboratory mixing chemicals'm him to bring you coins awards. Of all the bonus rounds in this game the most joy brought me a pick-em bonus. I'm not saying that, Respin reel and Sticky Wild worth less but I personally like the pick-em bonus round in almost all slot machines that come from Betsoft. My experience suggests that these bonuses are the best thing you can happen in the game, you need only look at the info from the slot machine and you will see what is the maximum gain in receiving bonuses.

This slot I play at Trada Casino because there have one active bonus that now going well and doubled my deposit + bonus, but we will see what will be the end of the rollover. I went with stakes of 0.60 coins per spin, and with the balance of € 130, and then I took the auto-play of 25 spins what has become a ritual when you go into a game Betsoft. I simply adjust the auto-play and watch the money come and go from my account. Immediately in the first spin I got Sticky Wild 5 spins in which I win 5 symbols of danger and after the round had a gain of € 25. There I stopped and I will continue tomorrow, because today is enough, thank you Madder Scientist - you are the best.
