Hellcatraz review
Hellcatraz is a prison / skulls themed slot from Relax Gaming, released in 2021. It runs a 6×6 layout with a default RTP of 96.23% and extreme volatility, meaning rarer but potentially huge wins.
The headline number is the max win: up to 51,840x your stake. That ceiling is reached through the game's bonus features and multipliers — not on the base game — so patience and bankroll management matter.
