About this Slot
Portal Panic is an action and sci-fi adventure game from Syntora Games with an RTP of 96%, medium volatility and a maximum win of 25,000x. It plays across 5 reels, 4 rows and 1024 ways to win.
Cascading reels trigger after each win, dropping symbols to fill empty spaces and creating chains of consecutive paylines. Multiplier coils reset with each base game spin but persist throughout free spins, increasing in value when paid spin symbols land in adjacent cells.
The Unstable Portal expands an entire reel to wild status. Once triggered, it remains in place until a spin without a win occurs on that reel, though the portal carries over to the next spin if the winning payline does not land on it.
Volley fires 1 to 5 random wilds onto the reels during base game or free spins, never during cascades. These wilds will not replace scatters, portals or existing wilds already on the board.
Three scatters award 8 free spins and guarantee a wild reel on reels 1 to 3. Four scatters also award 8 free spins but instead guarantee an Unstable Portal. Five scatters award 8 free spins and unlock the Panic Bonus.
Portal Bonus costs 100x bet and locks the first board while preventing additional scatters from being added during cascades. Overcharged Bonus costs 300x bet and begins with multiplier coils already set at 2x. Mad Experiment costs 500x bet and randomly awards a Portal, Overcharged, Panic feature or nothing.
