There is an interesting story behind the Speakeasy name. These used to be establishments that sold alcoholic beverages during the Prohibition era in the US. Long before that time, the phrase was used to describe a smuggling house or any other not so legal establishment. Once Prohibition ended, these houses no longer had a purpose, but the name remained, as still some Retro style bars are called that way, which brings us to our location at hand, the bar of Speakeasy Boost.

You know you deserve a little time for yourself. Grab a drink, listen to some live music and just enjoy the evening. This is the picture that Kalamba Games wants to paint with their latest release. Quite recently we had an opportunity to visit another such establishment called The Paying Piano Club. Both slots have their similarities, but Speakeasy Boost seems to take it a notch up with a grand 52,520x max win potential. Time to travel down in History to roaring twenties. Let’s talk about the Speakeasy Boost club.

Gameplay and Payouts

Smooth jazz fills the atmosphere, as the band begins to play their nightly repertoire. Speakeasy Boost has a vibey feel to it. Gentle music and dimly lit art deco style room is one heck of a combo. It may be a regular 5 x 3 layout, but the beautiful decorations make it seem a lot fancier. The main thing that defines Speakeasy bars is the booze, so it’s maybe questionable that the main focus of the slot is the music and the band that plays it. It’s not like we’re desperate for it, but it would make a lot more sense with a name such as Speakeasy Boost.

This “problem” is especially noticeable with Speakeasy Boost symbols. The low symbols are steel-made art deco style 9, 10, J, Q, K and A, while the high symbols are a violin, piano, drums, cymbal, saxophone and a golden microphone that is the most valuable symbol of Speakeasy Boost. The difference between this symbol and the second-largest saxophone is huge, as one pays 3x for 5 symbols while the other pays 100x. Speakeasy Boost uses 243 paylines, so there are plenty of ways to make successful combinations, in case you were wondering why payouts for other symbols seem on the low side. Even more so, the symbol can come in split variants, meaning that one cell can contain a single, double or even triple symbol. Speakeasy Booster wild symbol is a lady that has a striking resemblance with Jessica Rabbit. She can come with an additional multiplier of 1x, 2x or 3x.

Speakeasy Boost hasn’t shied away from big numbers. In general, Kalamba Games like to go large, but the Speakeasy Boost slot takes us to new highs. All eyes are on the 52,520x max win, which rightfully is a bonkers number. With such payouts, it is no wonder that volatility also is high. The RTP for Speakeasy Boost is 96.50%. Kalamba has made sure that Speakeasy Boost is well optimized on all devices. The bet range for this slot is 0.50 – 60 EUR/GBP. 

Bonus Features

It will be hard to get some good payouts with just regular symbols, that is why it is essential to score some Free Spins if you wish to reach that max payout. It’s very interesting how the Free Spins feature is triggered on Speakeasy Boost. There are 3 bonus variants/levels. The higher the level the bigger the potential. Each bonus level has its own scatter, which is a different member of the band. Free Spins are triggered by 3 bonus symbols of the same type, but before we begin with them, it’s important to take a look at another feature.

KBoost will determine your initial Free Spin amount and the wild multiplier that comes along. During the Speakeasy Boost base game, the meter above the reels fills up with each new spin. The more you manage to fill it up the more spins you get. So to simply put it, the longer you go without triggering the bonus, the better the bonus will be once you do activate it. To make your bonus game longer, you will need to score additional scatters. Two scatters award +2 spins, 3 award 5, 4 award 8 and 5 scatters award additional 10 Free Spins.


The roaring twenties were exciting times for many reasons. It was the era of wild parties, mafia mobs and just the birth of a whole new culture. Speakeasy Boost barely scratches the surface space though. The whole jazz band idea is fun for a moment, but it gets boring rather quickly. It also feels like Speakeasy Booster could have portrayed the real Speakeasy culture more accurately. It is a beautiful presentation, but it doesn’t do justice to what that era was really like. The biggest potential surely comes from Free Spins, but the only way to get some huge wins is to make it longer with a bunch of additional Free Spins, so that can be a slight nuisance.
