Although the futuristic sci-fi theme is not the easiest to work out, the presentation is top-notch. As for the bonus features, the slot revolves around the fittingly named Fire Portal wilds, which appear after cluster wins disappear from the reels. They hold multiplier values, which increase as they help to create more wins - and if they complete winning combinations with other wilds, they'll merge and multiply their values.

Fire Portals is a cluster pays slot set on a 7×7 grid, where wins are triggered by clusters of 5 or more matching symbols. This structure offers players numerous ways to win, emphasising the game’s dynamic and engaging mechanics.
The fact they're called Fire Portal Wild Symbols should give the game away a bit - but it's these lucrative wilds that take centre stage in Pragmatic Play's latest slot. Yes, they substitute for regular symbols just like standard wilds, but these offer much more than just that.
They will appear in one of the positions of each winning combination after all other winning symbols have been removed. As standard, they have a multiplier value of 1x, which increases 1x each time the symbol helps to create future winning combos, and they'll also move up, down, left, or right by one position each time.
The heart of Fire Portals lies in its Fire Portal Wilds. These symbols can substitute for all others except the scatter, appearing randomly after a win. Starting with a multiplier of x1, each win involving a wild sees its multiplier increase, adding a layer of excitement and potential for big wins.
Triggering the Free Spins is a game-changer, with 3 to 7 scatter symbols awarding up to 18 free spins. During these rounds, Fire Portal Wilds stick around, increasing your win potential. Plus, if wilds are present when free spins are triggered, they carry over, and the feature can be retriggered, keeping the action going.
