Fun fact! Number 15 can be divided by 5, 3 and 1, which in the case of 15 Coins™ stands for 5 bonus symbols to enter the bonus round, 3 rows of reels to fill in order to hit an increased Grand Jackpot and 1 outcome – you having a blast! Got you hooked? Continue reading for more!

15 Coins™ derives from the extremely popular 9 Coins™ slot and is the fifth addition to this booming series. What made this family of slots stand out from their competitors is their unique math model and solution that seemed overly unconventional, but turned out to be a game-changing innovation that led the series to become top performers. I am speaking of course about the lack of payouts in the base game, which results in a much more lucrative and thrilling bonus round. But let’s not get ahead of ourselves!

This new Wazdan title puts a premium on the simplicity of gameplay, with a classic 5×3 reel layout. In this shiny slot, you won’t find any paylines, as all 15 reels spin separately. Speaking of layout, the graphic design of this game is truly top-notch – not only all in-game animations are vibrant and smooth, but the slot’s colour palette combined with high-quality assets make up for quite an immersive experience, which is additionally enhanced by an euphonious sound design.

Now, let’s address the main appeal of the 15 Coins™ slot – the Hold the Jackpot bonus round. Upon activating the bonus game, you are granted 3 respins with a goal to cover as many reels as possible. Although 3 respins seem like an underwhelming amount, here comes the fun part – once you draw a symbol, the respin count is reset.

To enter this thrilling coin-demonium you have to cover all the reels in the middle row with symbols. What symbols, exactly? Well, all of them! The game includes the following: Cash symbol represented by a shiny coin icon that awards prizes, Cash Infinity™ symbol represented by a red coin icon, Collector symbol represented by a chest full of golden coins, Mini, Minor, and Major Jackpot symbols, concluding with Mystery and Jackpot Mystery symbols. All the listed symbols appear in both the base game and the Hold the Jackpot round.

Let’s get familiar with what this bunch of symbols has to offer, starting with Cash and Cash Infinity™ symbols. Apart from enabling you to enter the Hold the Jackpot bonus rounds, both of these symbols pay 1x-5x and 5x-10x your bet correspondingly, although Cash Infinity™ comes with a little twist – once drawn, it sticks to the reels until the end of the next bonus round. How does it help you? Well, firstly if you manage to land it during the base game on the middle row, then you will have one reel less to cover to enter the Hold the Jackpot bonus game. Secondly, as was said previously, they stick to the reel until the end of the bonus round, so the Cash Infinity™ symbols make landing a Grand Jackpot a walk in the park.

Next up is the Collector symbol. Upon drawing it, it will collect all the values from the Cash and Cash Infinity™ symbols, sum them up, and multiply them randomly by 1-20x. This combination can lead to incredible sizes of wins, especially if you have managed to also draw one of the Jackpot symbols. Stumble upon the Mystery or Mystery Jackpot symbols and you can be sure of a rain of gold! At the end of the bonus round, these wonder symbols can transform into other bonus symbols apart from the Cash Infinity™ symbol. The Mystery symbol can transform into Cash, Collector, Mini, Minor or Major symbols, while the Mystery Jackpot symbol can transform only into Mini, Minor or Major Jackpot symbols. These Jackpot symbols pay 10x, 20x, and 50x correspondingly.

Although the variety of Jackpot symbols offers lucrative prizes, the real treat is the ultimate prize of 15 Coins™ – the Grand Jackpot. It isn’t easy to get your hands on it, but it is worth the spins! To get it, you will have to enter the bonus round and cover all the reels with bonus symbols, after which you will be awarded the Grand Jackpot worth 1000x your bet! But to increase your chances to enter the bonus round and spin for great prizes, in 15 Coins™ you will find…

… the brand-new Chance Level mechanic! By default, the game is played with the base set. However, with an introduction of the Chance Level feature, you can boost your chances of entering the Hold the Jackpot bonus game! Furthermore, this feature has three levels: x2, x3, and x5; each multiplying the bet and your chances by the corresponding number. However, the Chance Level feature doesn’t affect the paytable, thus symbol values remain the same as for the base bet in both the base game and the Bonus Game.

Once you run out of respins or manage to cover all 15 reels with symbols, the bonus round finishes and all the winnings are summed up. But there is a twist. If you consider yourself a lucky individual, then you might try your chances by using one of Wazdan’s classic features – the Unique Gamble Feature. This addition allows you to double or nothing your winnings up to seven times in a row. And the best part is – the Grand Jackpot is also eligible, and you can walk away with winnings worth even 128000x your bet!

Apart from the Unique Gamble Feature, this slot offers a plethora of innovative features such as Volatility Levels™, which lets you adjust the size and frequency of your wins, Buy Feature that takes you straight to the Hold the Jackpot Bonus round, Ultra Fast Mode that, as the name suggests, massively increases the speed of your spinning, getting you to your prizes faster than ever before, and many more!

Summing up, 15 Coins™ is a slot that provides countless hours of fun thanks to a selection of engaging features, a unique math model and immersive audiovisuals. This game is a title to be reckoned with, so don’t wait and try this slot for yourself to explore the shiny riches that await in the world of 15 Coins™!

Don’t bother waiting – just spin it!
