About Koi Princess

NetEnt’s Koi Princess is a 5-reel, 3-row slot with 20 fixed paylines. Over the years, the game has acquired a cult following among slot lovers who have a thing for anime and similar art.

In the backdrop is a scenic waterfall with a traditional Japanese temple on the other side. The Koi Princess herself guards the reels. To play, you must spin the fishes and unlock riches.

But Koi Princess is more than just a game with good graphics inspired by Asian pop culture. It comes bundled with 9 bonus features filled with Sticky Wins, Wilds and Free Spins, which makes it a must-play.

Low-value symbols include the royals A, K, Q, J and 10. Landing 3 or more of them on a payline registers a win. Mid-value symbols include a bunch of traditional ribbon-tied Japanese coins, a green dragon and a golden dragon. Landing 3 or more of them on a payline will land you a win.

The Koi Princess and ocean wave, which is also the Wild, are the highest paying symbols. You need to land at least 2 of them for a win. The stakes have been set between €0.20 to €200, which suggests the game caters to players of varied budgets.

Volatility, RTP and Other Details

The volatility of Koi Princess has been set to medium, which makes a fine middle ground between low and high volatility machines. Such games are usually a tad frustrating because wins are not frequent. But when you win, you win big.

Medium volatility slots often come with loads of bonus features, which explains the 9 bonuses in this slot.

The RTP is 96%, which is decent compared to most other slots. If we consider the bonuses, the RTP goes up to 96.23%. Theoretically, you would receive 96 to 96.23 for every 100 you bet.

With the hit frequency being 28.74%, you are likely to land a win for about a quarter of spins. The maximum you can win in Koi Princess slot is 1000x your total stake in a single spin.

Koi Princess Features

Koi Princess is a slot much ahead of its time. Who knew NetEnt could come up with a game with 9 bonus features way back in 2015! Of them, 4 Random Bonuses can be triggered on any spin. There are 4 more triggered features as well.


The ocean wave Wild symbol cans how up on any reel and substitute for other symbols, thus forming a winning combination. Wilds in Koi Princess are the highest-paying symbols, too.

Bonus Bet

Every spin in this slot offers a chance to activate the Bonus Bet feature, which, in turn, doubles the cost of your stake. But, it also raises the chances of other Bonus Features being triggered.

Meanwhile, if the Coin Win or Free Spins round gets unlocked in the process, it would be the cherry on the cake that will further increase your winnings.

Random Bonus

Koi Princess offers 4 Random Bonus features which can be activated randomly during the base game. On any single spin, you would be able to choose from 3 carps to activate 1 of 4 Random features, which are as follows:

  • 5-Hit – get a 5-symbol win for sure with a randomly selected symbol.
  • Random Wilds – Between 4 and 9 Wilds are added as overlay symbols across the reels for a single spin.
  • Wild Reels – Get one spin between 2 and 5 reels filled with Wilds
  • Bonus Game activation – 3 bonus game symbols are added to the reels to activate the main bonus round that will let you play one of the triggered features

Bonus Features

When you land 3 Scatter symbols on reels 1, 3 and 5 on a single spin, the Bonus Features get activated. In the presence of 2 bonus symbols on the reels, the 3rd one gets nudged into place. Here is what you will get:

  • Sure Win Free Spins – you will get 10 free spins initially. Thereafter, you are sure to land a win worth at least the highest amount won during the free spins.
  • Wild Reel Free Spins – yet again, you will get 10 free spins. On every single of these spins, reels 1 to 5 will b filled with Wilds.
  • Coin Win – bag an instant coin win of 15x to 30x your total stake.
  • Bonus Wheel – this is a three-tiered wheel game where players can win coins to activate two more free spin bonus rounds. You must click the dice on the screen to spin the wheel. Each tier comes with 12 symbols: Start, x1 (for activated Bonus Bet), x2, x3, x5 (for deactivated Bonus Bet), Double Up, Collect, Arrow, Wild Reels Free Spins/Sure Win Free Spins and Jackpot Coin Win.
