Malta-based casino games provider Relax Gaming has expanded its portfolio with the launch of its latest slot Hellcatraz.

The 6×6 slot game takes players on a retro-style slot adventure as they attempt to break out of prison on an isolated island off the shores of San Francisco, as inmates search the jail for prizes worth up to 46,656x their stake.

The jail’s reels are filled with Mystery Symbols that appear as a countdown and reduce with each cascade, revealing their symbols at zero. Players can choose between Lockdown Mode or Mixed Mode that start at the same counter values or different ones, respectively.

Key Symbols award up to 10 keys each and collecting 2000 of them unlocks Super Free Spins. Here, the Mystery Symbols immediately reveal themselves, and Golden Mystery Symbols trigger additional spins with just two cascades.

“Our latest video slot, Hellcatraz, is an action-packed journey inside a prison island where big win potential thrives and mystery is widespread,” said Relax Gaming chief product officer Simon Hammon. “With low polygon visuals inspired by the pixelated games of the 80s, a stunning soundscape and immersive gameplay, this rollercoaster of a game will make an exciting addition to any operator’s slots portfolio.”
