Slot theme

Koi Princess has an Oriental theme centred around a main character who is reminiscent of female Japanese anime characters, plus koi carp, or jinli or nishikigoi, the fish represented in Asian culture, including Chinese feng shui, artwork and tattoos. There are various beliefs about the positive effects koi carp can bring, such as good fortune, prosperity, courage and a long life. So it is a perfect symbol to appear in this Koi Princess Slot, where these creatures appear to lucky players offering a random bonus.


In Koi Princess, players can find the regular 10, Jack, Queen, King and Ace symbols, plus Frog and Lion symbols, the Koi Princess, a three-pendant symbol, a Dragon Bonus, and a Wave Wild, reminiscent of Hokusai’s Great Wave of Kanagawa.


Sure Win Free Spins

With this nice bonus feature you have a good chance of a big win – first you receive 10 Free Spins and you are ‘sure to win’ because for every spin you will get a return at least equal to your original stake. So, with 10 Free Spins, you will win at least 10 times what you wagered. Also, look out for the gold dragon in this Sure Win Free Spins round! This creature is lucky for some as it can leave up to five random Wilds on your reels. If the dragon brings a bigger win than what you staked, you will then be guaranteed to earn at least that amount multiplied by your initial stake for each of your 10 Free Spins. If that sounds complex, here is an example: if the gold dragon brings you a win of 20x your original bet, each of your 10 Sure Win Free Spins will be multiplied by at least 20.

Wild Reels Free Spins

This feature gives you 10 Free Spins and, luck-depending, between one and five reels will be full of Wilds on each spin.

the Bonus Wheel

This will remind some players of various TV shows, like Wheel of Fortune, where the player or host spin a six-foot tall wheel with segments representing different prizes. Whatever the wheel lands on is what the player wins. The wheel has Start, x1 to x5 multipliers, Double Up, Collect, Arrow, Wild Reels Free Spins, Sure Win Free Spins and the Jackpot Coin Win.

Coin Wins

This is more simple – players win a coin amount instantly.

Random Wilds

Players will get a re-spin including four to nine Wild symbols, giving players a decent chance of a satisfying win.

Wild Reels

Players get a re-spin plus two to five reels will be filled with Wild symbols – it’s a nice extra and another chance to win a sizeable amount.

5-Hit Feature

Players get the chance to spin the wheel which gives them a symbol plus a Wild which will create a five-symbol combination. The win can multiply if more relevant symbols fall in place.

Bonus Bet

With the Bonus Bet ‘activated’ players have the chance of unleashing one of the four random features, either the 5-Hit Feature, Random Wilds, Wild Reels, or the Bonus Round.

What our experts like

We like the imagination put into creating this Casino Slot. There are so many clever win mechanics woven into the Koi Princess Slot that players could find themselves happily playing, and hopefully winning, round after round. However, just because there are plenty of fish in the sea, it does not guarantee players will net a gigantic win. We are also fans of the Asian Anime theme and think it brings something refreshing to the world of Online Slots.

We also like how unpredictable Koi Princess can be – with so many ways to win and various features, players never really know what is coming next. A combination of edge-of-the-seat anticipation and multiple ways to win is hard not to like.
