A trip to the prison isn’t entirely a fun-filled outing, however, Relax Gaming manages to make the whole experience exciting and rewarding on this Hellcatraz slot.

This retro-style 8-bit slot gives you an insight into the dealings in Alcatraz, one of the world’s most famous prisons. In line with the theme of the game, Hellcatraz features diverse low and high paying symbols and offers tons of bonus features and free spins that can be won with a single spin on the reels.

Hellcatraz slot is played on a 6×6 grid layout with 46,656 Paylines. Matching 3 symbols of a kind from left to right will trigger a win and if you’re able to unlock the game’s bonus feature, it will pay out up to 51,840x your stake.


How to play

Before you get to spin the reels, you would have to choose between two modes – Mixed Mystery symbols (high volatility) and Lockdown Mystery Symbols (Super High Volatile).

With that done, you can stake between 0.10 to 20 credits per spin. The symbols are styled after the famous Alcatraz prison. You will find a prison guard, a prison, a gold-toothed shark, handcuffs, badges, and playing cards.

Hellcatraz Slot Special Features

Special Symbols

The giant letter “W” is the wild and it will help in forming wins by substituting all regular symbols.

Bonus Features

Mystery Reveal Feature

With each spin made, Mystery symbols will appear on the reel and with each cascade, the counter on the mystery symbol is reduced by one. When it reaches zero, the mystery symbols are revealed which then turn into the same symbol. The mystery reveal feature can take off in two modes.

  • Lockdown Mode: All mystery symbols are connected to the same counter.
  • Mixed Mode: Two independent counter values are offered. They could be the same value or different values.

Key Collector

With each spin, keys will randomly appear on top of normal symbols. Players are rewarded with 1-10 keys for each key symbol.

Super Free Spins

Once 2,000 keys have been collected, the Super Free Spins feature is activated. During each spin, Mystery symbols will be present on the reels but this time, they will be revealed randomly without any cascades required.

If the Golden Mystery symbol is revealed in the bonus round, you will be awarded additional spins. However, two cascades are required to claim additional spins with this mystery symbol.

Buy Feature

If you can’t wait to collect 2,000 keys, you can always pay your way into the Super Free Spins round. This costs 200x the bet size.


You won’t get a jackpot prize on this slot, but a max win of 51,843.3x your total stake awaits.

Return to Player (RTP)

With a Return to Player (RTP) of 96.83%, there is great hope for huge wins on this slot.


Though the graphics of this slot isn’t a winning feature, it does have the right set of bonuses to compensate. The base game payout is pretty much meagre but with a single spin in any of the bonus games, a whopping payout of 51,840x the stake can be triggered.
