The Wild Portals Megaways slot is another game in a long ling that uses the Megaways mechanic (created by Big Time Gaming). There are 6 reels and up to 117,649 ways to win. Randomly on each spin, between 2 and 7 symbols will appear on every reel.
The more symbols per reel, the more ways to win. To play with 117,649 ways to win, you will need 7 symbols landing on each of the 6 reels. To get a win, you need 3, 4, 5 or 6 matching consecutive symbols, regardless of position, from left to right and starting on reel 1. The only exception is the highest value symbol where only 2 are required.
Stakes range from 20p to £16 per spin. There’s a stake box to the right of the reels (on the desktop version) or below the reels (on the mobile/tablet versions). You will see arrows which, when you click on them, will change your bet accordingly. Outside the UK, you will find an Autoplay function for autospins with loss and single win limit options.
The Wild Portals Megaways RTP is 96.58% which is quite high compared to most online slot games. As you’d expect the volatility is sky high with big wins available on every base game spin as well as in the free spins.

Theme – step into another dimension
Theme: Sci-Fi
High Value Symbol: Purple Gemstone
Compatibility: Mobile, Tablet, Desktop

With a sci-fi theme, the Wild Portals Megaways slot is set in an experimental lab. With a futuristic feel, the game provides a portal to another dimension. Benefitting from bright lights and a blue/purplish colour scheme, the graphics and visuals are clear and high definition.
Symbols include A, K, Q, J, 10 and 9 royals. You’ll also see 4 higher value symbols which include green, blue, red and purple gemstones. The purple gemstone is the best paying symbol with 2, 3, 4, 5 or 6 in combination awarding 0.25, 0.5, 1.25, 2.5 or 10 x your total stake.
The W Door portal symbol is the wild and substitutes for all paying symbols. Landing 2 or more will trigger the Wild Portal feature which is described in more detail in the ‘Bonus Features’ section below. The gold Energy portal symbol is the scatter and key to triggering the Free Spins feature.

Wild Portals Megaways Bonus Features
The Wild Portals Megaways slot has 3 bonus features. Central to the action is the Wild Portal feature where the Wild Portal opens and removes 1 random low value symbol. With the Wild Portal multiplier each time it happens by 1, this also applies during the Free Spins feature as 1 Wild Portal symbol appears on every free spin. Finally, you have a Win Exchange feature where you can play the free spins when you win 75 x stake or more. You can also gamble to win the free spins if you win between 25 and 75 x stake.
Wild Portal feature

On every spin, a 2×2 Wild Portal symbol can appear on reels 2, 3, 4 or 5. Substituting for all symbols bar the scatter, 2 or more wilds will trigger the Wild Portal feature. The door opens and reveals the A, K, Q, J, 10 or 9 symbol.
All instances of this chosen symbol is removed with the Wild Portal multiplier increasing by 1. New symbols then appear and the Wild Portal can roam and update to reveal a different low value symbol. The process repeats until no more instances of the reveal symbol appears on the reels. Each time this happens, the multiplier increases (by 1).
Free Spins feature

The Free Spins feature is played when 3 or more gold Energy portal scatters appear anywhere on the reels. 3 will give you 8 free spins with 2 additional free spins awarded for each extra scatter. For example, 4, 5 or 6 scatters will give you 10, 12 or 14 free spins respectively.
Then 1 wild portal symbol is guaranteed to appear on each free spin. With the Wild Portal multiplier carried over from the base game, this can increase by 1 during the feature. The multiplier can only increase. 3 or more scatters will give you extra free spins. 3, 4, 5 or 6 scatters landing during a free spin will give you 2, 4, 6 or 8 extra free spins, with no limits.
Win Exchange feature
Like with Apollo Pays Megaways, there is a Win Exchange feature. When you win 75 x your total stake or higher, you can activate the Win Exchange feature and get 8 free spins. If exchanged, the Free Spins feature will begin with a Wild Portal multiplier of 1x.
Now, win between 25 and 75 x your total stake will see you gamble to win 8 free spins. You will see a wheel with red and green segments. Landing on a green segment will activate the Free Spins feature (with 8 free spins) whilst landing on red will take you back to the base game.
Wild Portals Megaways Summary – unique feature teleports you to riches
The Wild Portals Megaways slot is a typical Megaways game with free spins and an increasing unlimited multiplier. However, the difference is the roaming Wild Portal which removes all instances of symbols and increases the multiplier.
With the bigger wins coming during the Free Spins feature, the max win of 20,200 x stake per base game spin is high. The multiplier doesn’t revert to 1x in the free spins so overall payouts of 29,580 x stake can be achieved.
Whilst this is impressive, Apollo Pays Megaways offers 116,030 x stake max wins on each free spin which is substantially higher. Another option is Pirate Pays Megaways (also by BTG) where 104,400 x stake wins can be won on every free spin.
If you want a sci-fi themed game, I personally recommend Starburst XXXtreme by NetEnt. With random wild multipliers up to 450x, there are no free spins but it does offer 200,000 x stake top payouts per spin.
- 29,580 x stake max wins
- High 96.58% RTP rate
