The Spinboss slot features a total of 10 symbols, including low-paying card values (Ace through Nine), high-paying character icons representing various members of the New Moscow crew, and two special symbols: Wilds and Scatters. The game’s paytable rewards players with generous payouts for landing combinations on active paylines.

- Wilds:
- The Spinboss himself serves as the Wild symbol, substituting all other icons to form winning combinations.
- Scatters:

Payouts
The game offers a relatively high Return-to-Player (RTP) percentage of 95.56%, which translates into average payouts for players over extended periods. The maximum payout per spin is set at x2,000 bet level, making it an attractive option for both casual and serious slot enthusiasts.
Wilds
As mentioned earlier, the Spinboss serves as a Wild symbol, allowing him to substitute any other icon in the game except Scatters to form winning combinations. While this feature enhances gameplay flexibility, players should note that Wild substitutions do not trigger bonus rounds or increase payouts beyond base-game rewards.
Scatters
The Scatter symbols are represented by the ‘Free Spins’ logo and trigger a separate bonus round when three or more appear on the screen in any position. During Free Spins, players receive 10-20 extra rotations depending on their initial scatter count, with all winnings accumulated outside of regular spins.
Bonus Features
In addition to Free Spins, Spinboss also offers several other enticing features:
- Sticky Win : Activates when a player lands multiple consecutive wins; the winning icons remain locked in place for subsequent rolls.
- Gamble Mode : After each win, players have two options: Double or Quit. If they choose to double down, their winnings are risked again at increased odds.
Free Spins
