Hellcatraz key features

mystery symbols

Mystery Symbols show up in this slot, although they behave a little differently to the usual style. Each one appears locked behind bars with its own countdown. After every cascade, the Mystery Symbols remain in place while their counters drop by one. Once a counter hits zero, all revealed Mystery Symbols flip to the same matching symbol.

How they behave depends on the mode you are playing, with two distinct versions to choose from.

Mixed Mode

In mixed mode the Mystery Symbols do not all share the same countdown. Some might start at 3, others at 5, all appearing together on the same spin with their own individual counters.

Lockdown Mode

In lockdown mode all Mystery Symbols that land together will share one countdown. This is the super high volatility option, designed for players who enjoy bigger swings. It can take a while for the shared counter to hit zero, but when it does every Mystery Symbol reveals at the same time for a powerful payout boost. Be prepared for a very volatile ride.

Key Collection

Hellcatraz also comes with a Key Collector Metre that unlocks the Super Free Spins round once you gather 2000 keys. Keys appear at random during base play and build up over time, once you've collected 2000 the round begins.

Once you make it into Super Free Spins, the mystery symbols work differently. None of them have countdowns and plenty of them drop in on every spin. With so many reveals happening throughout the feature, the round can deliver some seriously exciting results.

Hellcatraz Summary

Hellcatraz takes the classic prison break idea and flips it into a retro arcade riot, complete with pixel guards, clanging bars and over 40,000 ways. Mystery Symbols tick down like little time bombs, free spins shake up the pace and the Key Collector Metre slowly edges you toward a full blown breakout. It is frantic, quirky and full of character, the kind of online slot where every spin feels like you are inching closer to freedom. Perfect if you like your slots with a bit of chaos and a lot of personality.
