The 5×4 slot sees a tattooed Santa and a number of criminal Christmas characters fill the reels, where stacked walking wilds can trigger a respin on any turn, as players chase a max win of 5,000x.

When three or more bonus symbols land, eight free spins are awarded, during which random cells are framed. Every time a new wild lands more frames hit the reels, until an entire column is framed.

Once this occurs, the walking wild respins occur, this time with multipliers of up to 3x attached, to further boost winning potential.

Santastic 4 becomes the latest ESA Gaming title to explore the potential of stacked wilds, following recent hit Record Spins, as the provider continues to produce innovative twists on familiar concepts. 

Josefin Uppeke, head of game production at ESA Gaming, said: “Christmas has come early with our take on a festive slot, taking fun-loving characters and giving them a menacing makeover.

“With stacked wilds, respins, walking wilds and potential to collect plenty of multipliers, Santastic 4 is another bold addition to our portfolio as we gear up for an exciting period of game launches.”
