Boo Casino’s Jackpot Bonus Feature Review
The Boo Casino slot is a 5-reel, 30-payline game developed by Nolimit City. It has a horror theme and features a unique bonus system with four different jackpot levels. The game can be played on both desktop and mobile devices.
Game Theme and Design
The game’s theme revolves around Halloween and the supernatural. The reels are set against a dark background, complete with cobwebs and a haunted mansion in the distance. The symbols feature various Boo monsters from horror movies, including Frankenstein’s monster, Dracula, Jason Voorhees, and Freddy Krueger.
Symbols and Payouts
The paytable is arranged vertically on the left-hand side of the reels. The low-paying symbols are represented by playing card suits (9-A), which offer payouts ranging from 1-4 times the bet per line. The mid-tier symbols include a skull, a bat, and a werewolf, offering payouts between 5-20 times the bet per line.
The high-paying symbols feature Frankenstein’s monster, Dracula, Jason Voorhees, and Freddy Krueger. These offer payouts ranging from 25-100 times the bet per line. The scatter symbol is represented by the Boo Casino logo and offers a payout of 200 times the bet if five appear on an active payline.
Wilds
The game features two wild symbols: a regular wild, which substitutes for all other symbols except scatters, and a special expanding wild that expands to fill the entire reel when it lands. The special expanding wild is only available during free spins and has no effect outside of this feature.
Scatters
Scatter symbols appear on any of the reels and don’t have to be on an active payline to trigger free spins or bonus games. A minimum of two scatters must land in view to activate the Free Spins feature, while three scatters will award 10, 20, or 30 Free Spins.
Bonus Features
The Boo Casino slot features a unique jackpot system with four progressive jackpots that can be won at any time during regular play. These are awarded randomly and have no influence on gameplay. The bonus levels are: Mini Jackpot (2000x bet), Minor Jackpot (10,000x bet), Major Jackpot (50,000x bet) and Mega Jackpot (200,000x bet).
The free spins feature is activated when two or more scatter symbols land in view. Players can receive between 5-30 Free Spins depending on the number of scatters that landed during initial activation.
During free spins, all winning combinations pay out a multiplier based on the symbol’s original value multiplied by its corresponding free spin multipliers, which range from 2 to 10x. Free Spin rounds are played with an automatic re-trigger option at end, except for those earned as part of our Grand Feature Bonus – see below.
RTP and Volatility
The Boo Casino slot has a Return To Player (RTP) rate of 96.15% across all bets. While high in line with market norms it is worth noting that there are variations depending on stake bet, higher wagers reduce to just over 92% and lower stakes bump back up to the original value.
Volatility falls under “very High” category meaning more variance in short-term sessions due to infrequent hits yet substantial rewards when triggered.
