game ReviewThe games game can be found at NetEnt casinos. NetEnt do make the house edge information of their slots games available and this can be found in the help files of the game (usually accessed by pressing the ‘?’ button at the bottom left of the game window). NetEnt games appear to only have one setting. The variation in House Edge is accounted for by the decision to switch the ‘Bonus Feature’ mode on, with the lower House Edge occurring when the Bonus Feature mode is activated.Will these glorious fish bring you wealth?Koi Princess is a 5 reel game, with 20 paylines and you can bet up to 10 coins on each payline.

Koi Princess is probably one of the best NetEnt titles of all time, at least in our humble opinion. The 2015 release is packed with additional features, which may seem a bit complicated in the very beginning, but you will find your way around soon enough. If you activate the Super Bet, you will increase the probability of triggering features, but pay close attention, because it can easily suck your balance dry.

The theme of this slot is none another Asian theme, the concept of this one diverges much from the rest because its design focuses not just on traditional culture of some eastern region, but its concept focuses on the mix of traditional culture, specifically Koi fish farming, with something that fully identifies contemporary Japanese culture such as its widely known drawings called "animate".

In essence this slot includes two different types of special features, the random functions and bonus rounds; the first ones appear unexpectedly at any time during the base game and on them you can get lines of 5 of a kind with a randomly defined symbol on a sort of wheel of fortune, many simultaneous wild symbols, wild reels and even access to the main bonus round. Bonus rounds for their part, are triggered in the conventional manner by obtaining 3 scatters identified with the image of the dragon and the word "Bonus", and through this function you can get prizes as they are instant cash, a wheel of Fortune, a round of free spins with sure winnings and another one with wild reels, all of them are supremely exciting features and potential of each varies between decent and great; my favorite bonus round, which by the way I could get access a greater number of times, is the round of 10 free spins with sure wins where your best last hit gives you an additional free spin and automatically becomes your guaranteed minimum payout for each of the remaining turns, so that in "Sure Win Free Spins" it is vital to get a good hit in the first two or three spins because of that it will largely depend on your final winning for this round. In addition you can pay double bet in order to activate some feature that gives you a major chance of triggering bonus rounds, and its use may be part of the strategy of the player.

In my opinion this is one of the most genuine, complete and funny slots manufactured by NetEnt so far and I hope this game to continue its good behavior in the future by being equally or more generous than I could see today.


tivating this option doubles the the cost of a spin and increases the probability of awarding a random feature and a bonus feature as well as changing values on the bonus wheel and increases sure coin wins for sure win free spins.

I must to say that this really changed everything. I played without this option, but the game was not so interesting. I had only small winnings, no bonuses or any random features. I decided to activate this bonus bet and all changed. Not in very first spins, but in over 100 spins all changed.

I received random feature a few times after I changed this, before I did not received it once. The random features are great, all of them. Maybe the payouts could be better, but random feature appear quite often with bonus bet and I like it. I also like that you have to select one of the fish to reveal the feature.

I also received free spins. Sure win free spins. It was interesting because all I won during those free games was sure win. Nothing more than that. But I like this game anyway.

The game really offer a lot of different features and I like it. You never know which feature you will play. I will rate it with 9 stars, it is a great game.

I had a few free spins offers but you can't make a decision about a game only from few spins, so when an offer of 50 free spins came across, I claimed it.

This game has 5 reels and 20 paylines, the minimum bet is 0.20€ however if you want bonus feature activated, it will make your bets twice bigger. At first I didn't know that, but I really recommend to use this extra option, because if you do, you have bigger chances to activate random features such as wild reels, random wilds and two others. All my free spins were played with minimum bets and without the bonus activation. I was quite upset as I won only 3€ from 50 free spins. I then continued to play this game with only 17€ balance, and played with the 0.40€ bets so that I had the bonus activated. Very soon I triggered bonus round, it is triggered when bonus symbols are on 1st, 3rd and 5th reel.

The reason I really like this game is that the amount of features it has is incredible. From all features I got fortune wheel. In it I had mutipliers and when I had collect symbol, the feature would end. However the first time I ended with dragon symbol, which also gave me 10 free spins. I overall won 35€ which seemed like a great start, and to add, I triggered this bonus within the first 30 spins. Then I had many times random features, my favorite is wild reels because then the fish turns reels wild and in most occasions it turned 3 reels wild. It gave me a maximum of 25x bet win because there weren't high value symbols.

My second favorite feature is called Sure win free spins. I received 10 free spins and when I received a win, it became a sure win, so if I later had a no win spin, I would still get the sure win. I managed to get a win of 2.35€ and that was a good amount for sure win, and this feature gave me 100x bet winnings. This is a really handy feature.

This game absolutely fascinates me. It has decent design, it reminds me something of Manga and overall the graphics are great. I can assure that no one will get bored while playing this game, it is fun and the best part I experienced was when few times I had only 2 bonus symbols, one of the fishes locked the screen and tried to get the 3rd bonus symbol and few times it actually awarded me with bonus round, so that is a really nice surprise in my opinion, it’s called a Nudge and I’ve never seen something like that. I think it is definitely worth trying and the winnings I've experienced are more than pleasing.

e of the best looking game by Netent made this year. Absolutely nice graphic, sounds, and nice theme. All symbols are colorful, and I really love it. I am pretty happy that it is one of the last releases this year, and Netent make something looking bright, nice, and not dark. Good job and thumbs up.

First interesting thing, which about I was curious - it is some kind of bonus bet here. You can activate it, but it will double your bet. So if you activate it - your minimum stake will be 0.40, which is quite solid. Also it is increase chance to get bonus feature, but I have no idea how it is increase it.

There is two different in game features - first one it is three bonus symbols on reels 1 3 5, when you get it - you got feature. Second one is with fishes, and it is triggered by random. It then allows you to choose one of three fishes and get special feature. There can be guaranteed 5 of a kind win, also there can be bonus trigger, random wilds, or random wild reels. Worst pick is 5 of a kind trigger, but it is most common one.

Bonus feature is awesome, there is few different features, including sure win freespins, wild reels freespins, also bonus wheel, and coin win. Coin win is worst feature per my opinion, I got it once and won only 40 x stake.

I love this game, it is outstanding. I played it and lost on it about 200 euros already, but I will still play it, and will be happy to play again. Interesting slot, interesting potential, very interesting features.

I rate this game with 10 stars.


Koi isn’t such a princess. Koi fights and she fights for features and bonus games.

Koi, or Nishikigoi, are actually ornamental varieties of the domesticated common carp, kept for decorative purposes in outdoor koi ponds or in water gardens. 3 Kois will come out of the water, surrounded with waterfalls in this slot, and you will be offered to pick it up and reveal your prize. My prize was 5 hits on the wheel, that also came out of the water, and on the last stop, wild symbols came out, firstly giving a BIG WIN, and while the magic was happening, golden coins started spreading all over the screen and a SUPER MEGA WIN came as the final prize! I won 8 Euros on my 0.20 Euro bet size!

Koi Princess is the first of its kind when it comes to Manga, which are comics created in Japan, so we finally get to know what Manga means, and this was the first time that NetEnt used Manga for creating new games. Manga have a long and complex history in ancient Japanese art. Japan is one of my must visit countries, just like Koi Princess should be a must try slot too for all ladies. Yes, it does look girlish, and that might be the reason why the male population didn’t pay much attention to this entertaining and really very exciting slot.

Unfortunately, as for the paytable, I must state that it is really poor, so don’t be surprised if this slot eats all of your balance, because the maximum win of 500x the line bet is only possible if you can collect 5 WILD symbols on a payline, which is very hard to get. No matter the poor paytable, I truly like this Koi Princess slot and I will continue to play it. For those who haven’t yet tried this game, I can recommend it, and everyone should at least give this game a try!


A beautiful lady, or girl, or princess, always make her game more exciting to play, right guys? Ah-hah, you see...even the ladies are nodding their heads! Hahaha.

First of all, before you even start playing this game, you must decide whether to activate that Bonus Bet option or not. What it does is to double all chances of getting wins, double the chances of features, but double your losses too! That's because your bet per spin is doubled too! If you like it, you can use it. If you don't like it, like me, you can just ignore it. To me, this Bonus Bet thing is just a tricky ploy to make you lose faster! Do you think any game provider would actually want you to win twice as much or twice as fast? No way Jose! Sorry darling, just have to borrow your favourite line! Hehehe.

I do like the 4 random features available in this Koi game, namely, the 5-Hit, the Random Wilds, the Wild Reels and the Bonus Game. The 5-Hit 1-spin feature game guarantees a 5-of-a-kind win, but these are mostly small wins, I must admit. Only rarely can you get nice big wins. The Random Wilds 1-spin feature game can give you from 4 up to 9 random Wilds onto the reels. This can be real nice, if you're lucky enough. The Wild Reels 1-spin feature game, which is probably the best among the 4 feature games, can provide you from 2 up to 5 reels of fully stacked Wilds! So, imagine getting 5 reels of these fully stacked Wilds, and you'll be jumping up and down like a crazy monkey, or like a mad kangaroo, hahaha.

The 4th feature game, the Bonus Game, is actually more like a free spins game, with 4 different feature games available, and one will be awarded through a spin of the Bonus Wheel. The Sure Win free spins game provides 10 free spins with guaranteed wins on every spin. The Wild Reels free spins game provides 10 free spins with 1 to 5 reels having random Wilds. The Coin Win game awards coin wins. The Bonus Wheel game has 3 tires on the wheel, giving coin wins, multipliers, a Wild Reels feature game, a Sure Win feature game, and of course, a 'collect' symbol, to end the Bonus Game.

Wow! How many features does all that add up to? I'm too lazy to count, but I sure do know that this Koi Princess is so generous in giving away gifts, presents, coins and whatnots! It's simply of how lucky you can get with this bee-you-tiful princess, and also a matter of how much she likes you, or even loves you! Hehehe. For me, I guess she doesn't like me, yet. Don't ask me why, I can only look at the sky!


ere were times when I didn't get the random triggered bonus after 100 spins and there were times when the bonus were triggered on my very 1st spin and another 10 spins later another bonus was triggered. But in my opinion the bonus bet is really unnecessary and cost a lot of money. I prefer the bonus bet that NextGen provides, because it’s a portion of your total bet and not the same amount as your total stake.

There are four random features that appear in Koi Princess and each possesses its own super power. The 5-Hit symbol awards players with one free spin that includes a guaranteed five symbol win with a random symbol. The random wild will play a free spin with a few overlay wilds placed randomly on the reels. The wild reels feature ensures that any number from two to five of your reels is covered with overlaying wilds and bonus activation.

The bonus activation feature can be triggered during the random features or when 3 bonus symbols lands on reels 1, 3 and 5. This bonus game can give you cash prizes and trigger the 2 free spins games namely sure win free spins and wild reels free spins features. The Bonus Wheel is a 3 tiered wheel with multiple prizes, arrows and collect. Roll the dice to move around the wheel collecting prizes. Look out for the arrow symbol as this moves you inwards to the next wheel with bigger prizes on offer, but the closer you get to centre the more collect signs appear on the wheel. During this bonus feature you can also trigger the sure wins free spins feature.

Overall this is a nice slot, but I didn’t enjoy it. I only get some entertainment and excitement during the bonus rounds and I prefer to have some fun during the base game as well. This game focuses more on the bonuses it has to offer.


e five free spins I received from Stan James won me around £9 but I ended up going on to play for the entire evening with that money, managing to beat the 30x wagering requirement - something that doesn't happen very often at all with Stan James not least because they restrict you to playing the same game until you convert your balance to cash and you need a whole truck load of luck to wager the winnings from five free spins 30x and still have something left over no matter which slot you might be playing!

Koi Princess features several bonuses and most of them have great winning potential! There are bonus symbols on reels 1, 3 and 5 which can trigger either the "Sure Win Free Spins" or "Wild Reels Free Spins", both of which are fairly self explanatory. As you might expect the wild reels option has the highest win possibilities and it is even possible to get all five reels wild in this mode for a maximum win on all 20 paylines at once.

My favourite features are randomly activated though after any spin, a bonus wheel appears at the bottom of the reels and will choose one of four features when you hit the stop button. It's possible to enter the free spins bonus from here, random wilds can be added to the reels or you can be awarded a guaranteed five of a kind of a random symbol. I seem to be incredibly lucky with this one and very often manage to choose either the princess symbol or the wild, and it's great to watch these symbols being added to the reels knowing your about to receive a great win after the disappointment of a losing spin!

Base game payouts are quite small but that's okay with me as so much of the games RTP is obviously tied up in the wide range of different features, and the wild reel bonuses make it possible to win on a large number of paylines at once. Koi Princess has become one of my favourite games in a very short period of time and I love the fact it shows NetEnt still have the ability and desire to create great paying, fun games that also have their trademark first class presentation... now, if only they would do it more regularly!


With the bonus bet activated on $1.60 total bet, it took 8 spins for me to land 3 bonus dragon symbols for the bonus wheel before I had something "random" going on. As they landed, I spun the wheel and hoped my feature would not be the coin win, that is by far the worst to get but being it as it was very close to landing on it I had the bonus wheel for credits. In this bonus, it is a lot better than the coin win because there are 1x and 2x prizes per roll of the dice plus an increase slab and an arrow to advance deeper into the wheel. I know that once I reach the second sector of the wheel, it usually lands on a collect and it is rare for me to even advance further! I won $29.20, not too shabby for hitting it 8 spins from the start.

The random mini feature that has the bonus bet in gave me a chance for Wild Reels, the 5 of a Kind win of a random symbol generated by the symbol wheel, random wilds or an entry into the real bonus! All I did was choose 1 of the 3 Koi fish to get one! I might think but not sure if this extra bonus bet counts for that last bonus symbol nudging back and forth if the bonus scatters land on Reel 1 and 3 (or any other 2 bonus dragon combinations) after a suspenseful roundabout with the last bonus on Reel 5 has part of it sticking out to to make a teaser of whether or not the last scatter will land or will just go up or down on it's position!

If I had to choose one great feature to play it is the Sure win Free spins!!!! For every new win on any spin it will pay that much on the next spin while giving an extra spin for every time this happens!! If I had a losing spin, it will give me the current win. (Ie. current win is $15, it will give this regardless of the spin unless there is a bigger win than $15 then it pays that throughout the free spins). Koi Princess for a Netent slot has qualified to be a well entertaining video slot, it deserves a recognized 9.7 out of 10!


I have played this game numerous times and the outcome is always different.

Koi Princess is a 5 reels and 20 pay lines video slot game. There are 4 random features and they are as follows: Wild Reels Random Feature is the one that I was getting most of the times where you get one free spin and between 4 and 9 wilds. The next one is the 5 Hit Random Feature where you get 1 spin with a 5 of a kind win, but this win can be of weaker symbols so do not expect much. The Wild Reels Random Feature is also one that I was getting most of the times too and this is where you get 1 spin where between 2 and 5 reels become whole wild. The sad truth here is that I never got more than 2 wild reels, and every time the fifth reel becomes whole wild and I was getting nothing at all. The last one is the Bonus Activation Random Feature where you get 1 spin where you get 3 bonus features and only one will be activated. I never managed to get this feature though.

Probably the best part in this game is the Sure Win Free Spins feature. This is where you get 10 free spins and lots of wilds. During the first 5 spins you get a random wild on the first, third or the fifth reel. Then, after the fifth reel the wilds are added on the third, fourth and fifth reel. The highest amount that I have won during this feature was around 100 x bet. What comes as a surprise is that this feature can be triggered easily and to me it is the one that is the most rewarding.


If 2 Koi princess symbols appear, you will be offered to pick up your prize and see what's hidden behind. I won hits on the wheel but can't remember of how many. I played really long time ago and enjoyed this girlish game but I think guys could like it too.

Koi Princess have many features to offer.It's a 5 reels and 20 pay-lines video slot and you can play it as for 0.20 euro cents . There are Wild Reels, random Wilds , Free Spins feature and few more waiting on you to unlock it if you get lucky. I placed minimum bets and can't recall whether I activated Free Spins or not, but I managed to unlock Free Spins feature. I will not say it was my disappointment as I played only few times, but I won like 10 euros on my 0.40 bet size. Nothing but better tht then nothing. I definitely everyone stop complaining after only few sessions, no matter what game is, give it a serious try and then talk. I like this Asian inspired game but it's not easy trying out all these newest releases, plus the games you like and the games you love to play and wish to try out. Correct me if I am wrong.

Let me say that this game pretty unique features which will add special emotions and excitement that you won't find no where else but only in Koi Princess. Head up for original idea and the effort they put in while creating this great themed slot. I like when slot looks like original and Koi Princess surely is. It is worth trying and fun to play.


The difference between manga and animation is that manga is more artistic, no computer was used during the drawing (only paper and pencil). I have great respect for manga creators.

Koi Princess is a cartoonish game from NetEnt, as you can guess from the title and layout of the game, it has a Japanese style but the audio also gave it away. It is a very fun game and it's the second game from NetEnt that has optional extra feature. The first one was Alien Robots and I love that game. By turning on the extra feature, it increases the chance of the bonus feature being triggered which could be an advantage for players but extra doesn't mean it's free. As soon the extra feature turned on, the stake doubled instantly but the payout will stay the same. I think it's doesn't improved the chance of winning at all. It's a sort of a saving system that would be returned when the bonus round is triggered.

However, it's a great concept and I did used it a few times, only when bonus money is involved. Furthermore, I love the characters of the game, that's including the happy faced fishes and the crazy looking dragon. The best thing about Koi Princess is the bonus wheel feature. I honestly managed to reach the highest prize once. Of course it's hard to win that goes without saying. I also managed to get to the top of the Steam Tower and reached also grandmother's house in Fairytale Legends : Red Riding Hood.

The not so good thing about this game is the max win, it's not Dead or Alive, which max payout could be ridiculously huge but Koi Princess is still a fun game to play, it brings a little bit of Japan into your home. A little advise though, if you decide to play with extra feature turned on, don't play with a high stake.


The only bad thing which I noticed was that after random feature almost already started, it goes back to base game without giving you. It is a bad feeling when you saw that.


Awesome new game by Netent, what bad things there can be? Nothing.

Mrs Mills Neonrshall

What can I ever dislike about any beautiful princess? Nothing! Except for the game, that is. As good as the game Koi Princess appears to be, not everything that glitters is gold! The paytable is low, most payouts are low and I can't even get any blardy good show, so far that is, if you must know! Hehehe.
