Portal Master Bonus Features

Game Symbols

There are a total of 9 regular symbols in Portal Master. The low-paying category is represented by the card suits, while the high-paying category is represented by various badges. The featured card suit symbols are the clover, hearts, spades, and diamond. All of them have an equal maximum payout – 270 coins. The green badge is the first high-paying symbol in Portal Master. It has a maximum payout of 720 coins. Then, we have the blue badge which has a maximum payout of 1,350 coins. The purple badge has a maximum payout of 13,500 coins, and finally, the orange badge has a maximum payout of 225,000 coins. 

Apart from the regular symbols, there are three special symbols in Portal Master. The first one is the Portal Master Wild which acts as a substitute for all regular symbols and appears only on reel 3. It expands and covers the whole reel and grants players the second special symbol – Energy Spheres. The crystal acts as the Scatter.

Bonus Rounds & Free Spins

Earning Free Spins in Portal Master is not done via the Scatter. The Energy Spheres are at the centre of this feature. There are 3 types of Energy Spheres – Low-Level, Mid-Level, and High-Level. Free Spins are obtained by trading 2 Mid-Level Energy Spheres and one High-Level Energy Sphere. The number of Free Spins is randomly determined and it can be anywhere between 10, 15, 20, or 25. 

During the Free Spins feature, the Wild symbol remains on the third reel and is added to the second and fourth reel.
