Winlines/Ways to win

Journey to one of America's most well-known prisons in this slot. Hellcatraz is based on the reputation that Alcatraz created for itself as an inescapable prison.

You have the reels set in a building on an island, with the coast guard on watch from the water. To make things interesting, police helicopters fly by during the Free Spins round to help catch any escapees.

Its Pixelated Graphics, Animation, Music

Get immersed in old-school retro slots with this Relax Gaming title. The soundtrack is loud, and the graphics are reminiscent of retro video games. You can also hear the waves crash in the distance and police sirens.

The symbols also feature prison-themed graphics. These include images of a prisoner, guard, handcuffs, and even symbols behind bars.

Fun Gameplay

You start the game by choosing either the Mystery or Lockdown options. The game mode can be changed at any point after the current spin ends.

Low-value payouts come from the star, heart, clover and diamond. High-value ones include the guard, prisoner, gold-toothed shark, prisoner and handcuffs. Match between 3 and 6 of a kind to earn a payout.

Instead of spinning, the symbols cascade from above. As such, symbols in a win vanish. Then the remaining ones cascade, and more get added from above. Expect up to 46,656 ways to win on the 6x6 grid.

Bonuses, Wilds and Free Spins

The Mystery Reveal feature comes with symbols that are locked with a number value. With each cascade, the number reduces to reveal the mystery symbol. That replaces all occurrences of that number with the revealed symbol.

Players can collect keys randomly throughout their gaming rounds to unlock the Super Free Spins. There's a counter to the left of the reels, so you know how many you have. Alternatively, you can buy the feature, save your collected coins and get five free spins.

Bet Sizes and RTP

The bets on this slot range between 0.20 and 20 credits per spin. The RTP stands at 96.83% with this high volatility game.
