Mad Scientist Slot Betsoft

Mad Scientist is a 20-payline video slot which runs on the Betsoft software platform. The game features various scientific signs and objects that can be found in a well-stocked laboratory. There are several valuable icons, one of which is the wild, the Board, and another is the Switch, which is the scatter. Players can try the slot on this page for free or visit any of the featured Betsoft casinos to play the game for real money.

Before peeking inside the scientist’s mysterious laboratory, one should choose their bet. The coin value, which ranges from 0.05 to 1, is adjusted with the “Choose Coin Bet” sign. “Select Lines” alters the number of active paylines, while “Bet Per Line” adds a coin to the line bet. “Spin” initiates the game, “Max Bet” spins the reels at the highest wager and “Au­top­lay­” turns the reels for a preset number of times uninterrupted.

3 Bonus feature icons, the Lab Tubes, trigger the Mad Scientist Great Experiment Bonus round. Players join the scientist in his final test of his Turn-to-Gold serum. Earning more than 3 Bonus round symbols will lead to multiplied winnings. Players select any of the 4 objects to start the experiment. As the scientist drips his serum on the object, it turns bronze, silver or gold. Players are awarded when they help the scientist choose all of the objects to complete the experiment.

The Wild’o­’Cution feature starts when the Electricity symbol emerges on reels 1 and 5 on payline 1, 2 or 3. The Tesla coils activate, shocking themselves and the icons between them turn wild, increasing one’s chance of winning.

3, 4 or 5 Radiation icons on an enabled payline from the beginning or from the end one after another activate the Bio Pick Me Bonus feature. Wins which are in the range from 125 credits to 175 credits are multiplied with one’s bet per line and the number of lines where the combination occurs.

Scientists engage in all sorts of experiments, to uncover all the dark secrets in the world and in the universe, but only mad scientists would do the unthinkable, like trying to turn simple worthless things into gold. Hmm, I guess they are no different than any of us then - they also want to be instant millionaires! Hehehe. Unfortunately though, no mad scientist has turned into an instant millionaire so far, but that won't stop them from keeping on trying, as this one particular scientist is doing. Yeah, he's one of those Mad Scientist.

Playing with only 20 paylines, which is a rarity for BetSoft games, this Mad Scientist game plays with a minimum starting bet of either 0.20 or 0.40 per spin, depending on each casino's coin value setting. The one I played at starts at 0.40 per spin, but it's still not too bad, because the game pays both ways, left-to-right and right-to-left. Moreover, the play lines are selectable, so you can even start playing with just 1 payline, if that's any good at all, hahaha. The Blackboard is the Wild symbol in the game, a dumb symbol sadly, that only does substitution for other symbols except for the Scatter symbol, and not paying anything for itself, not doubling any wins, not becoming stacked or becoming expanded on the reels either. The Switch is the Scatter symbol, paying 250 credits for getting 5 of them, but doesn't trigger any free spins. There aren't any in the first place. Argh!

The Beaker is the Bonus symbol, another dumb symbol with no payout whatsoever, but getting 3 or more of them on any active payline triggers 'The Mad Scientist's Great Experiment' Bonus game. Pick 1 of the 4 items to be experimented upon, to turn it into Bronze, Silver or Gold, with corresponding rewards for each kind. Getting 4 or 5 Bonus symbols in triggering the Bonus game, the winnings would be multiplied, but by how much is not indicated. BetSoft paytables are typically very poor at giving full details. The Nuclear Sign is also another dumb Bonus symbol, and getting 3 or more of them on any active payline from the left reels or from the right reels, trigger the 'Bio Pick Me' Bonus game. Yep, to me it's another 'argh' game, but what to do. Pick 1 of the symbols to win from 125 up to 175 credits.

The Tesla Coil is the third dumb Bonus symbol, appearing on all reels, but getting them on both reels 1 and 5 at the same time triggers 'The Wild-O-Cution' Bonus game. Hmm, what a fancy name indeed, but one which is very difficult to get, for me at least. Nope, I didn't get any of it, so I have no idea on how it pays, but by triggering the Bonus game, symbols that are between these 2 Tesla Coils are turned into Wild symbols, thereby giving 5-of-a-kind wins, assuming that all symbols are turned into Wilds that is. The symbols in the game pay from 1000 credits down to 10 credits for getting 5 of each kind. Still a low paytable.


No doubt that I have played this Mad Scientist game several times before in the past, but I simply cannot remember of the payouts that I've gotten. Nonetheless, all were below 50x the total bet amount, because I don't even have one winning screenshot on the game. My most recent session got me a win of 6x from the 'Pick Me' game, a 7x win from one of the Bonus games, but nothing from the Tesla Coil Bonus game at all. A very disappointing game for me.
