With 8 bonus features, the Koi Princess mobile slot keeps you well entertained as you go searching for that fabled golden dragon.
We have so much to go through here, we won’t be able to touch much on the theme of this NetEnt slot machine.
Needless to say, anime/manga fans will feel right at home in this bright, colourful, game that is full of lucky symbols from the far east; from the 3 lucky coins, to the 3-legged frog (Money-Toad), the Fu-Lion, and the Princess Myoko keeping you company on the right of the reels.
We’ve written, in detail, what and how you catch each of the 8 bonus games in the Koi Princess slot in the bonus section below. This slot review, for now, is all about how it plays.
We played this Koi Princess video slot for about 2 hours before we even realised you could add the bonus bet. And we loved it even still.
It’s fun, it’s got random features that pop out of nowhere, and there’s so many variations on the wild symbol, chances are that if you can think it, this casino game will have it hidden somewhere underneath it’s soft glowing rivers.
However, what we did find is that our cash wasn’t really moving up or down by much. We got a few 30x and 40x our bet wins which gave us hope, but they weren’t easy to get.
Once we added the bonus bet (in the bet settings tab), you do double your bet, but suddenly the bonus feature hit once in about 20 spins, rather than once every 60 spins, which brought this game from 4 to 5 stars.
The danger, of course, is that whilst you are paying more, your bet level and coin value remains unchanged, so base game wins are almost non-existent.
Thank-fully the base game is just there to pass the time.
The stars of the show are the Sure Win free spins and Wild Reel free spins – which are almost impossible to catch without the bonus bet. Thank-fully, we’ve had just as good results with the random wild and 5-hit random feature, with or without doubling your bet.
Personally, we prefer to pay more to hit the big win features but know the base game wins are pretty much useless, rather than keep our balance steady and not lose much or win much.
That said, newcomers to mobile slots should forget the bonus bet all together and enjoy a lively Japanese theme with tons of features. More experienced players, on the other hand, will need that bonus bet to keep the thrill alive in the long term.
The Koi Princess slot game doesn’t have as big a wins as their other bonus heavy game South Park, but you’ll have so many high-thrill moments, you won’t care.

The Bonus Bet: Activating this option will double the cost of a spin, whilst keeping the current bet level and coin value the same.
So why bother if the wins are only going to be smaller from now on, in comparison to your overall bet?
Because it increases the probability of awarding a "Random Feature", as well as changing values on the Bonus Wheel (higher worth), and better odds of getting a higher sure win during the 'Sure Win Free Spins'.
The Random Features: At any point during your spin, three lucky Koi's will swim out from under the reels and you'll be asked to pick one.
In order of how often you are likely to get these:
Scatters and Bonus Features: You'll need to get the scatter dragon symbol anywhere on reels 1, 3 and 5. Without the bonus bet, it can take over 200 spins to trigger, so don't think it doesn't exist.
You are also more likely to get the Sure Win free spin feature in the bonus wheel you'll spin to randomly have one of the 5 features triggered.
These are in order of what we think give you the best potential for larger wins:
Sure Win Free Spins: You initially start with 10 free spins. Each spin, you are guaranteed to win a minimum of your overall bet, meaning you are guaranteed to walk away with 10x your bet.
The really good news is that the golden dragon flying behind awards up to 5 random wilds on screen, and if you get a bigger win than your overall bet, that then becomes your Sure Win amount. So say you win 40x your bet on the first spin. You are guaranteed then to get a minimum of 40x your bet on each of the free spins.
Each time increase the amount on your Sure Win, you also win one free spin. Don't get us wrong, a good average for this feature is about 20x to 30x our bet overall, but we can't help but watch the reels like a hawk for a large Sure Win.
Wild Reels Free Spins: You get 10 free spins where anything from 1 to 5 random reels will be chosen on each spin to be completely wild.
These free spins are pretty hit or miss. Mostly you only get one or two wild reels, which makes it hard to get that excited about - though no doubt one blazing round with 5 wild reels will change your mind.
The Bonus Wheel: This is a simple click me bonus where you roll a dice to go around a 3-tiered wheel. You can keep going forever, and sometimes it feels that way as you collect anything from 1x to 5x you bet.
The symbols to be on the lookout for are collect, which ends the game, the Double up, which doubles all the values on the wheels (so the maximum is now 10x) and the arrow that moves you further into the tiers.
The inner tiers have higher values, including the chance to win either of the free spin bonus, and the coin jackpot that range from 75x to 500x (depending on if you are playing bonus bet or not).
Coin Wins:The least interesting of the features. Here you win anything from x15 to x30 your overall bet. A nice little top up, but not exactly as exciting as the other bonus features.
We doubt the Koi Princess mobile slot will be for everyone. Those who are looking for more 'classic' game play, where they don't have to click and choose, but just spin, are better off playing something like the crazySpinata Grande slot.
For the rest of us, who have short attention span, need constant entertainment, and a huge variety of bonus games, you won't find a better NetEnt Touch game than Koi Princess.
Finding life-changing wins won't be easy, but with so many different ways for it to happen, and plenty of semi-decent wins keeping you spinning, this low to medium variance machine is damn near perfect.
Or you can play Koi Princess at one of these mobile casinos:
Review by Lucky Mobile Slots, last updated: February 23, 2021 - Rating
The theoretical Koi Princess RTP is 96%, but that increases to 96.23% with the bonus bet active.
The most you can win on a single spin is 1000x your total stake, which at min bet is 200 in cash and at max bet of 200 is 200,000 in real money. This can be achieved in the Bonus Wheel.
Find any good NetEnt slot site and you'll be able to play Koi Princess for free before you play for real money, although you may have to sign up or login to the casino first.
The Koi Princess volatility is low to medium offering a good mix of wins thanks mainly to the 8 bonus games it features.
There are 2 free spin bonus features the Sure Win Free Spins and the Wild Reels Free Spins. In the first you get 10 free spins with guaranteed wins where as in the second you get 10 free spins with up to five Wild Reels on each spin.
