Symbols and Winning Combinations of Doctor Winstein Slot

Winning CombinationsDoctor Winstein is a slot that is clearly themed around science and research. If players decide to give it a shot, they will join the scientist in his effort to combat the robots that pop up on the reels.

As players might expect, the reel engine is set somewhere in Doctor Winstein’s lab which is dark and gloomy. There are pipes all over the place, and the symbols appear against a purple background. The background audio is electrifying but is unlikely to distract players from the spinning action.

Overall, Doctor Winstein has 11 symbols, eight regular payers, and three that have special functions. All icons that pop up on the reels are perfectly drawn, and the least rewarding are the card faces J through A. If the winning combination is made of seven or more such matching symbols, reel spinners will bag a payout of 100x the line bet. The next most valuable symbols are the robots, and the yellow, red, and blue machines award payouts of 200x the line bet.

Even though these symbols are not special ones, winning combinations are formed in the same manner as the ones completed by scatter icons, meaning that their position on the reels does not matter.

Bonus Features of Doctor Winstein Slot

Bonus imageWhen players are ready to conduct experiments on the grind, they should prepare to use the bonus features Doctor Winstein offers. Cascading reels is one of the features that are sure to boost players’ expedition toward generous returns as thanks to it, they can strike multiple wins in a row.

Each time symbols form a winning combination, they will be taken down from the reels, and their place will be taken by the icons that stand above, which might lead to the completion of new winning combos. The symbols will stop cascading down when no further winning combinations appear. Reel spinners need to know that the replacement of the symbols will not cost them a dime.

As the main hero in the game, Doctor Winstein has a special role as he is the wild symbol. The scientist can land on the second, third, and fourth reels only, and can stand instead of regular-pay symbols, and not the win multiplier or the red button scatter icon. Whenever at least three Doctor Winstein images pop up on the reels at the same time, players will get a payout of 100x the line bet. If the winning combination is formed by seven or more such symbols, a payout that is 1,000x the line bet will be added to players’ bankrolls.

The red button is the scatter symbol in Doctor Winstein, and when seven or more examples of it appear together, players will strike a payout of 100x the line bet. Yet, seeing three or more red button scatter symbols will also result in a payout, and in addition to this, slot buffs will be awarded 15 rounds of free spins.

When they enter the free games, players will also get to benefit from a special multiplier symbol that cannot appear in the base game. When the special machine Doctor Winstein invented lands on the screen, it will take a multiplier value that is selected at random. Thanks to this special icon, players’ winnings from the rounds of free spins can be multiplied 2x, 3x, 5x, 10x, 15x, or 100x.

A classic gamble feature is also on offer, and players can enter it after each round in which a winning combination is formed. Still, this will only be possible if their winnings are less than 10x the amount they have staked. When the risk game begins, players can either attempt to guess the card color, which might bring them twice bigger payouts, or try to predict the card suit, which might result in a four-fold increase of their winnings. If players decide to participate in the double-up game, they should be warned that if they make a wrong guess, their winnings will be voided.


Doctor Winstein is a video slot that allows players to take a trip to the scientist’s lab and potentially make some great discoveries. This game might grab the attention of reel spinners who pursue something new and intriguing, and it offers a variety of features that might help them bag the biggest possible win of 1,000x the bet amount. Its RTP is below average as it stands at 95.85%.

Made with particular attention, Doctor Winstein’s visuals are indeed well crafted. The game is also compatible with all sorts of devices, which gives players the freedom to enjoy it whenever they want.
