Portal Master: Slot Overview
Using this unique gateway is the most convenient method to travel between parallel worlds. The Portal Master slot, developed by Mancala Gaming, is an online slot game that offers an original storyline. Set in a fantasy theme, this slot game is played on 5 reels and offers 1024 ways to win. Expect vibrant symbols and transparent reels with a dark backdrop. Within the stony matrix, levitating rocks can be found. The game also includes heroic music and well-crafted sound effects for an immersive experience. While users have the ability to customize various aspects of the game, the matrix itself remains fixed and cannot be changed. The Portal Master slot offers a bonus game, free spins, and several other intriguing features. It is compatible with both mobile and desktop devices, allowing players to enjoy it wherever they prefer. If you're interested, you can try it out for free on K8.io at any time.




Once you click on the sign marked with two yellow pointers, the excitement of playing the Portal Master video slot begins. As a result, the 5 reels and 4 rows will start spinning. It's advisable to explore all the available betting options before proceeding. In this game, you have a choice of 20 total bets. The minimum total bet is $0.10, while the maximum bet is $100.


Additionally, all the standard features commonly found in modern slots are included in this release. For instance, there's an Auto-play function that allows for up to 100 auto-spins and provides advanced options. Players also have the ability to accelerate the spins. You'll find a speaker button to control the sound volume and a square sign in the upper-left corner that enables adjustment of the screen size. Furthermore, there's a sign with three lines that leads you to the paytable and provides access to the history of your most recent gaming session.


Portal Master: Slot Features

Portal Master features a total of 9 regular symbols. The lower-paying category consists of the card suits, including the clover, hearts, spades, and diamond. Each of these symbols offers a maximum payout of 270 coins. On the other hand, the higher-paying category consists of various badges. The green badge has a maximum payout of 720 coins, followed by the blue badge with a maximum payout of 1,350 coins. The purple badge offers a maximum payout of 13,500 coins, and the orange badge carries the highest payout of 225,000 coins.


In addition to the regular symbols, there are three special symbols in the game. The first one is the Portal Master Wild, which serves as a substitute for all regular symbols. It only appears on reel 3 and expands to cover the entire reel. Furthermore, it activates the second special symbol called Energy Spheres. The crystal symbol acts as the Scatter in the game.




The Energy Spheres in the game have a crystal-like appearance and can be stored in the Collection Stone on the left-hand side of the screen. The Collection Stone can hold up to 6 Energy Spheres. These spheres have multiple uses - they can be used to transform scatters into regular symbols or saved to trade up for more powerful features. There are three levels of Energy Spheres:




  • Low-level Spheres: These spheres occupy 3 slots in the Collection Stone. They can be used to transform scatters into a random regular symbol.
  • Mid-level Spheres: These spheres occupy 2 slots in the Collection Stone and can only be acquired by trading up all 3 low-level spheres. They have the ability to transform not only the scatter symbol but also create a 5-of-a-kind line, guaranteeing a win.
  • High-level Spheres: These spheres can be acquired by trading up the 2 mid-level spheres. They occupy only 1 slot in the Collection Stone and reward players with a random number of free spins.


Crystal scatters, although they pay 30 times your stake for 5 on a payline, do not trigger the bonus round. They are primarily used to be transformed when players utilize the Sphere feature. The only way to access the Bonus Round is by trading up the 2 mid-level spheres for the high-level sphere.


The Free Spins feature initiates automatically once the trade is completed. Players are randomly assigned 10, 15, 20, or 25 spins. During the feature, there is a chance to land extra expanding wilds on reels 2 and 4. However, wilds in the bonus round do not award Energy Spheres. Each wild landed provides an additional spin as a bonus.




Portal Master: Slot Verdict
It's uncommon to come across a slot game that allows players to choose how to utilize collected items. Mancala Gaming is undoubtedly an experimental developer, but the success of this feature remains uncertain. From our perspective, there seems to be little reason not to save up and trade for the bonus round, as a random 5-of-a-kind win usually doesn't yield significant rewards, let alone the individual symbol transformations. Therefore, while there is an innovative aspect in triggering the free spins feature, there isn't much else that stands out as innovative in the game. The presence of an expanding wild on reel 3 in the base game and on the 3 middle reels during the bonus round is not particularly groundbreaking either.



  • Ability to collect energy spheres
  • Option to transform scatters or trade up
  • Trading up to tier 3 triggers the bonus round
  • Bonus round includes expanding wild on the 3 middle reels



  • Below-average RTP of 95%
