About the Game


Koi Princess provides the player with a slot experience that anyone would be happy playing – with an aesthetic that is meant to mirror feudal Japan, there are a number of art decisions that make this game stand out from the rest. NetEnt have created an online slot game with huge customisation options, which also helps it stand out even more. The background features a temple, surrounded on all sides by a very stereotypically Japanese scene – a waterfall cascading into a calm pool. The music is also highly reminiscent of this era, with string instruments, drums and flutes perfectly capturing the atmosphere the developer is aiming for. Coupled with the symbols’ art style, as well as the remade (classical) casino slot symbols, this slot game is very easy to play and look at!

The game itself functions in a few more complex ways compared to others in the industry. You will notice in the bottom right of the screen that there is an option for ‘bonus bet’ – selecting this option doubles your bet amount, but it increases the chance to get extra bonuses and multipliers. Is this worth it? I recommend trying it yourself! In this vein, there are FOUR bonus features! The 5 Hit Random feature awards the player with a guaranteed four normal symbol win. The Random Wild Random feature gives you a single free spin with four to nine overlayed wilds placed on the reels. Next you have the second type of Wild Reels, with one free spin, but two to five reels are COMPLETELY covered in wilds.

The Bonus Activation Feature gives you one spin, where three bonus symbols are presented with a bonus feature. ON TOP of these, you see three bonus features appear across reels one, three, and five, you are guaranteed incredible chances to get extra winnings! You have Sure Win Free Spins, Wild Reels Free Spins, Coin Win and the Bonus Wheel. All of these options function as individual ‘unique’ features to games in their own right, so to have all of them in one game is mind-boggling!

The Verdict


With the minimum bet being 0.20, and the maximum (including the bonus bet doubling) is an absurd 400, both the high rollers and low rollers alike will appreciate Koi Princess. In my opinion, this online slot game puts all others to shame. With beautifully animated scenes, coupled with the chance for incredible bonuses, this truly is the pinnacle of online slot gaming.
