"Fire Portal" is the latest cluster paid slot with "Roming Wild" from iGaming Content Provider Plagic Play Ltd.
The Gibraltar-based company said in a release on Thursday that the 7×7 grid of high-variance games with magic and mystery-themed emblems would need to connect more than five symbols, either horizontally or vertically, to win.
With each victory, the winning combination is replaced with a new symbol and Fire Portal Wild is added to the reel.
The wild contains an initial 1x multiplier, increasing by 1x each time it becomes part of a new winning combination during spin.
Each Fire Portal Wild can reach a maximum multiplier value of 2,500 times, the vendor said.
If three or more scatterings occur, a bonus round will begin, with up to 18 free spins given when seven symbols reach.
Irina Conides, chief operating officer of Pragmatic Play, said: "Fire Portal is the original new slot of Pragmatic Play featuring roaming wilds, which can win up to 10,000 times. It's a visually recognizable 7x7 game with a unique mechanism."
The fire portal has joined recent releases such as "Sugar Rush 1000" and "Loki's Boo."
