Speakeasy Boost

Go back to the 1920s, where you get to experience an authentic lifestyle during the prohibition era when an illicit establishment that sold alcoholic beverages known as 'speakeasy' was listed!

The Kalamba Games team has decided to take you to a jazz club featuring quite an unexpected lead singer – a Jessica Rabbit look alike!

Enjoy the smooth jazz sounds, use 243 ways to win and groovy bonus features such as the dev's favorite HyperBonus, as well as Splitting Symbols and Free Spins, and grab the maximum potential prize of 52520x the stake!

Theme and Symbols

The first thing that takes you straight to the past is the game's theme-related soundtrack, an authentic jazzy tune that creates a unique atmosphere of this retro-themed online release!

The action takes place in an empty jazz club, standing in the transparent reels' background, with a set of instruments waiting for the performers on the left, red comfy chairs in the middle, and a massive bar to the right.

The reels feature some theme-related, beautifully-created icons, including playing card symbols from 9 to A created in an art-deco style, followed by a cello, a piano, drums, cymbals, a saxophone, and a retro-style microphone, while...

...the red-haired singer is the Wild, and the three band members all represent Bonus symbols!

Overall, the game boasts impressive visuals, perfectly created according to the theme with dimmed lights complementing the atmosphere to perfection.

Betting Options and Other Functions

This jazz-themed online title from the Kalamba Games slot list is played across 5 reels and 3 rows while offering 243 ways to win.

It is a high-volatile online game that features an above-average return to player percentage of 97.49%, the hit frequency of 28.68 (see details here), and the max potential win of 52520x your total stake from a single spin!

Before you travel back in time, though, you need to set your bets that range from 5 p/c to £/€60 per spin.

When it comes to the paytable, it starts with the low-payingplaying card symbols, paying up to 1x and 1.5x the stake, while the two of the high-rewarding instruments – the sax and the microphone – pay for two in a combo, and up to 3x and 100x the stake, respectively!

The Bonus symbols also pay up to 10x the stake on their own, while the Wild symbol substitutes for all other regular symbols and appears as an x2 and x3 multiplier Wild during the bonus round!

Special Features

Before we start with the game's special features, we should also note that all of the regular symbols have the ability to land as split symbols, meaning they come in double or triple versions!

Now, when you load the slot, you will notice the three meters above the reels that showcase the current number of free spins you have accumulated.

These meters represent the three different versions of the bonus round, and each of them starts with 7 extra spins that can then go up to 25!

After you fill the three meters up and then manage to hit three bonus symbols, you will trigger one of three different Free Spins game levels.

The 3 K-Boost accumulation meters correspond to the different tier bonus rounds:

• x1 multiplier bonus round - awards seven free spins +1 extra spin per 15 paid spins.
• x2 multiplier bonus round - awards seven free spins +1 added spin per 33 spins.
• x3 multiplier bonus round - awards the same number of free spins +1 extra spin per 50 paid spins!

Depending on which jazz musician Scatters trigger the Free Spins round, you will get the corresponding bonus. 

As we have already mentioned, the Wild symbol lands with x2 and x3 multipliers during these special spins and count as 2 or 3 matching symbols when they land. 

Land 2 to 5 scatters during the bonus round, and they will award 2 to 10 extra spins, respectively!

Lastly, thanks to the dev's well-known HyperBonus feature, punters can opt to buy the bonus round directly and choose between 4 bonus buy options, each coming with a different number of free spins, multipliers, and the RTP percentage!

Verdict

Speakeasy Boost is a decent online slot machine from Kalamba Games' slot portfolio with an innovative theme, stunning visuals, and a nice pack of features that may seem a bit complicated at first!

Nevertheless, thanks to the game's K-Boost accumulation meters, the slot's engagement never stops and, although only one regular symbol actually lands a decent prize, the game boasts double and triple symbols, as well as multiplier Wilds that help significantly in winning more frequent and proper awards!
