Introduction
The SpinBoss casino slot machine is a game developed by Rival Gaming, a renowned online gaming software provider. The game features an intriguing theme of crime and punishment, with five reels and twenty paylines set in a stylish 1930s-inspired setting. Players can enjoy the thrilling gameplay experience on both desktop computers and mobile devices.
Theme and Design
The SpinBoss slot machine is centered around the spin boss theme of organized crime in the United States during the Prohibition era (1929-1933). The game’s design features an abundance of dark, gritty colors with neon-lit highlights. Players can expect to encounter symbols such as a speakeasy-style cocktail bar, police cars, detectives’ hats, and most notably, infamous gangsters like Al Capone and Lucky Luciano.
The game’s background is set against the silhouette of Chicago’s famous skyscrapers at sunset, creating an immersive atmosphere that puts players in the shoes of outlaws on the run. The five reels are placed above a series of 20 paylines, where combinations of symbols can reward cash prizes ranging from modest to substantial amounts.
Symbols
The slot machine boasts an impressive array of 25 regular symbols, divided into high-paying and low-paying categories:
- Low-payout symbols: standard playing card values (9-Ace), along with four icons of cigars.
- Medium-paying symbols: a pair of revolvers, champagne bottles, binoculars, a fedora hat, and three versions of the ‘Lucky 7’ symbol in blue, red, or silver.
- High-payout symbols: Al Capone’s portrait ($1.20 payout), a cocktail bar (up to $12.00 payout).
- Wild symbol: The Jackal (pays up to $24.00 per combination) is depicted as the game’s protagonist and main character.
Payouts
The slot machine provides various payouts for combinations of symbols:
- Single-payline wins start at 0.02 credits with a high-payout potential reaching $12,000.
- Maximum payout: Al Capone can award up to 500x your total bet ($1.20 or more).
- Max free-spins win limit is also linked directly to the chosen stake.
Wilds and Scatters
The Jackal (main character) serves as the game’s Wild symbol:
- Replaces other symbols in combinations but does not replace Scatter.
- Awards up to 500x total bet for a single occurrence on the first five reels.
A pair of ‘Federal’ and ‘Al Capone’ are classified as two separate, specific Scatters that will trigger special features.
Bonus Features
Two main bonus rounds exist within SpinBoss slot:
- Gangster Wilds : The Jackal (Wild) creates 2 to 5 copies in place of each appearance on screen.
- Crime Scene Free Spins : A set number of consecutive free-spins awarded when at least two federal Scatters fall anywhere during regular game play.
Free Spins
- Up to thirty, or more consecutive spins may be triggered from any combination and win amounts based solely upon user bets made per round.
Gameplay progresses normally; wins are granted but ‘freeze’ does not occur. Upon completion of all extra turns the accumulated payout is added on top of actual outcome.
Return-to-Player (RTP) Rate
SpinBoss Casino Slot has an RTP value set to a minimum 94% – maximum payouts vary.

The volatility index is relatively high, as only one or more rare wins trigger this particular slot machine. The minimal bet starts at $0.01 while the maximum allowed wager reaches up to $125 with no restriction on number of times per round when altering stakes value through “Bet” function.
Max Win and Maximum Payoff
The progressive jackpot accumulates all single spin rewards until achieving max payout threshold ($500x or over).
