Koi Princess is a NetEnt slot launched in 2015. The game boasts a 96.23% RTP. This non-progressive slot game also features bonus bets, bonus games, wilds, and mobile. This game has a jackpot of €200,000 and is available for playing on both desktop & mobile.



We just know there are some fans of manga and anime among you – a style curiously underrepresented among top online slots. Well, the NetEnt Koi Princess slot game has been around for quite a while now. It’s fairly famous for its adorable presentation and exciting features.

Koi Princess slots by NetEnt is a 2015 online slot game packed full of crazy features and a strong RTP rate. It’s fairly unique even among the best slots online, largely thanks to features like Wild Reels and Random Wilds. Let’s start from the beginning, though.

The base game is fairly standard for this type of game. It’s played on a 5×3 table with a total of 20 active paylines. As such, your goal is to arrange identical symbols from left to right, starting at the first reel. There are 9 regular symbols, resulting in a decent amount of variance. The volatility itself is fairly average, but the relatively small table means the hit rate is not too high.

That doesn’t mean the payouts are bad, mind you. The Koi Princess RTP rate is a fairly strong 96.23%. Still, the majority of the excitement in this title comes from the special symbols and bonus games.

Casino Chick Best tips for Koi Princess Slot

  • We strongly recommend activating the Bonus Bet feature. Without it, a lot of the extra features won’t work.
  • The Bonus Bet doubles the stake. Still, the minimum bet for Koi Princess by NetEnt is very low, so you can still keep the stake at a reasonable level.


There are two main reasons to play Koi Princess for real money – the aesthetic and the special features. We’ll let you judge the looks on your own. As far as the features go, here’s a detailed overview.


During regular play, the biggest payout you can get is 400x your bet for 5 Koi Princess symbols. However, the biggest payout comes from the Koi Princess Bonus Wheel. Some fields move you towards the center. If you land three of them, you win the Koi Princess jackpot of 1,000x your stake. The Bonus Wheel is one of the more high-paying features in general.

Understanding the sometimes complicated features is the key to knowing how to play Koi Princess by NetEnt. For instance, the Wild Reels can also lead to exceptionally high payouts. As previously stated, this all combines into a strong 96.23% RTP. However, not paying the Bonus Bet lowers this rate to 96.00%.

what we like

  • The element of randomness adds to the excitement
  • A plethora of special features keep you wanting more
  • A well-crafted game with a clear direction

what we don’t like

  • Not paying the bonus bet is a waste. The stake options could have been structured better.


As you can see in our Koi Princess slot game review, NetEnt’s developers got very creative with this one. There are more features than you can count, so each spin brings new excitement to the table. All in all, it’s a great addition to NetEnt’s already impressive portfolio. One thing’s for sure – there’s nothing quite like the Koi Princess slot game out there, and that’s always a big plus.
