Slot Features

The Professor Big Win slot machine is played on a set of 5 reels with 4 rows each. The game has 40 paylines for you to score wins on. Winning combinations in the game are made up of three or more matching symbols across a payline, starting from the leftmost reel. The Professor Big Win game has an RTP of 94.07% and a medium volatility. Bets in the game range from 0.40 to 120 per spin.

The symbols in the game are made up of low-paying card royals and higher-paying themed symbols such as pen and paper, microscope, a flask, jar, and the professor which is worth the most out of these. The game also has a Wild symbol which is the most valuable symbol in the game. It can substitute for all regular symbols to help complete winning combinations.

As you play the game, you may experience the Mystery Replacement feature which will change some of the symbols on the reels into matching ones at the start of each spin.

Another feature of the game is the Replicating reels feature which may trigger at random or by landing 2 Electric Scatters on the reels on the same spin. A respin will take place if the feature is triggered and the special Replicating Reels will be synchronised, giving you a chance to land a winning combination.

The Free Spins feature can be triggered by landing 2 or more Free Games symbols on two or more reels. You get 7 free spins wherein the Replicating Reels feature is active at all times. You can land full stacks of the Free Games symbols on the reels during the feature. A special High Voltage mode also comes into play during the free spins bonus.

An optional Buy Bonus feature is also available where you can buy the free spins feature for 120x your stake.
