Theme and Design

There is not much to talk about when it comes to the game’s design. Everything fits the classic vibe, especially the way in which the symbols and additional buttons are drawn. The soundtrack really fits the vibe and to some it might remind of popular theme songs from masterpiece mobster movies.

During the free spins the music gets much more alert which creates a lot of excitement and tension that will resolve at the end of the bonus round, when you will finally see how big of a prize you earned.

Wager limits

Because of the adjusting paylines, the wager limits can fit many playstyles and are very customizable. Both beginners and experienced players will be able to find comfortable amounts to play with. However, keep in mind that less paylines might also mean smaller chances of landing a winning combination, so make sure you plan accordingly.

Bonus features

The game sticks pretty close to the classic slot formula so there arențt many special features about which to talk about.

  • Free spins – landing at least 3 Scatter symbols will trigger the free spin rounds. The free spins are played in the same bet value and number of lines as in the previous round which triggered them.

  • Wild symbol – the Wild can substitute any symbol in a winning combination, besides the Scatter.

Slot tip: The game still pays pretty well regularly, so don’t count too much on the free rounds if you are looking to make a profit.

RTP and volatility

The Slot Boss RTP is 96.56% which is considered to be above average. Also, the medium volatility will allow you to experience longer playing sessions with small wins which will keep you in the game and special rounds which will bring you more considerable amounts. Overall, you will enjoy this slot regardless of you being a safe player or a risk taker.

Symbols

Though the graphics are a little bit outdated, the game still manages to play around with the design of its symbols to make them a little bit more interesting. The playing card symbol, J, Q, K and A are combined with human features which gives them a little bit of personality, regardless of the fact that we’ve already seen them in most other slots thousands of times.

Slot Boss Royal Symbols

Matching the theme, you will also encounter a vintage car, a whisky glass, a bullet and a man pointing a gun. The Scatter is a woman smoking and the Wild is represented by piles of dollar bills.

How to Play Slot Boss

The old-fashioned interface might turn many players away as it can feel pretty clunky from time to time. In this section we will explain where you will find all the useful buttons and what each one of them does. Below the grid, going from left to right, you will see: the auto-spin function, the payline selector, the coin value selector, the win amount indicator and the spin button. Pressing the spin button one more time in the middle of the round will fast forward the falling of the reels.

Slot tip: Your total bet value is a combination of your coin value and your number of activated paylines. Increasing one of these values will increase your total bet. You might want to play around with these functions in the Slot Boss demo mode before jumping into the real game.
