Koi Princess online slot game

NetEnt are not usually renowned for developing slots with a plethora of bonus features but Koi Princess is certainly one of those. Two free spins rounds, a bonus wheel, random wilds, and wild reels are just some of these while players can increase their chances to unlock them all by using the Bonus Bet.

Theme and Story Line

Japanese anime and Asian pop culture is the inspiration behind Koi Princess and it will not be long before you fall in love with the workmanship that has been put into this title. Dragons, turtles, Chinese dollars and of course the cute little Koi Princess adorn the reels as you go looking for your big payday.

Graphics, Sounds and Animations

Koi Princess would not be a NetEnt slot if it did not contain some impressive graphics and animations. This video slot exudes quality from top to bottom in this regard thanks to high-quality anime-style graphics, some superb animations, and an oriental soundtrack that fits the theme of the slot perfectly.

Koi Princess is a 5-reel, 25-fixed pay line video slot from NetEnt. All wins pay from left to right while the combinations that can be made will usually require at least 3 symbols. The exception is the Wild symbol and the Koi Princess symbol which both need a minimum of 2-symbols to create a winning combination. Those two symbols alongside the dragon, turtle and Chinese dollars are also the most lucrative as they hold the best payouts.

The Wild symbol will be able to help create winning combinations as it can substitute for all other symbols while the Bonus symbol will be what is needed to trigger the bonus rounds. 

Be sure to check out the paytable in-game to learn more about the possible win combinations, the bonus features, and the rules of the game.

Bonuses and Free Spins

Random Features: There are four random features that will be triggered at random as you are spinning the reels on the Koi Princess video slot. These are:

  • 5-Hit Random Feature: If this triggers, you are given a single free spin which is guaranteed to land you a five-symbol win.
  • Random Wild Feature: This is also a single free spin but this time with the addition of between 4 and 9 extra wild symbols added to the reels.
  • Wild Reels Feature: Another free spin but with anywhere between 2 and 5 reels being turned completely wild.
  • Bonus Feature: If triggered, this will launch the full bonus feature as described below.

Bonus Feature: This feature can be triggered as part of the Random Features above or through landing three bonus symbols on the 1st, 3rd, or 5th reels. On some occasions, if you land two of those bonus symbols, the third might get nudged onto the reels. Once triggered, players will spin the wheel below the reels to be rewarded with one of the following four bonus games:

  • Sure Win Free Spins10 free spins with a guaranteed win from each. Additionally, each win is guaranteed to be equal or greater than the last.
  • Wild Reels Free Spins: 10 free spins with a random number of the reels being set completely wild before each spin.
  • Bonus Wheel: This will give you a spin of the Bonus Wheel. Here you can win access to one of the above two bonus rounds or receive a coin payout.
  • Coin Win: Players will win a coin payout.

Bonus Bet: The Bonus Bet can be activated or deactivated on the interface and is an additional bet of equal size to your total spin bet. This bet will give players an increased chance of triggering random features and bonus features and will also increase the rewards found on the Bonus Wheel and in the Sure Wins Free Spins round. 

Bet sizes, RTP and Variance

Koi Princess is a video slot that will suit players of all budgets thanks to a betting range of a minimum bet of 0.20 and a maximum of 200.00. Changing the bets is done by setting the coin level between 1 and 10 and is essentially how many coins you wish to wager on each of the 20-fixed pay lines. The coin value setting determines the value of each coin between 0.01 and 1.00. 

96.23% is the RTP of Koi Princess while it has been deemed a medium variance slot. The latter is probably down to the wide range of the betting options and the numerous bonus features. 


Some slots look great but have no depth while some offer depth while looking dated. Koi Princess manages to combine the two and delivers an excellent online slot experience that is a mix of aesthetics, playability, the potential for big wins, and numerous bonus features.
