Koi Princess is powered by Net Entertainment and is a 5 reel, 20 payline slot which is available on desktop, mobile and tablet devices. Playable from 20p to £200 a spin, it’s the most feature-packed game they have ever made. It has an exquisite Oriental feel to it with brightly coloured lucky charms and a traditional, yet soothing, Japanese soundtrack. You will see the Princess to the left of the reels giving you encouragement and support.

On to the features – there are 4 randomly triggered features in the base game. Known as the Random Feature, you will click on 1 of the 3 kois to see which feature you will play. The 4 possibilities are as follows:

  • 5-Hit Random feature – this gives you 1 spin with a guaranteed 5-Hit win taking a randomly chosen symbol and payline.
  • Random Wild Random feature – again gives you 1 spin with between 4 and 9 overlay wilds placed on the reels.
  • Wild Reels Random feature – you get 1 spin where between 2 and 5 reels become whole wild reels – overlay wild symbols cover the chosen reels.
  • Bonus Activation Random feature – you will be granted 1 spin where 3 bonus features are presented – only 1 random feature can be activated from here.

Now onto the bonus features which can be played when 3 bonus symbols appear simultaneously on reels 1, 3 and 5 – this will award you with a randomly chosen bonus feature (which are described below). If you get 2 Bonus symbols on the reels, a 3rd Bonus symbol can be nudged onto the reels. The 4 Bonus features are described below:

Sure Win Free Spins feature – this will give you an initial 10 free spins. The win for each free spin will be at least the same as the largest amount won during this feature (except for the 1st free spin). Now, for free spins 1 through 5, 1 overlay wild is added randomly to either reels 1, 2 or 3.

After free spin 5, an extra wild is randomly added on reels 3, 4 or 5. The positions of the random wilds change for each free spin by the way. Finally, you can win more Sure Win free spins which are added to the total.

Wild Reels Free Spins feature – here you again get 10 free spins with between 1 and 5 random reels covered with overlay wild symbol. This changes for each free spin but you can get up to 5 wild reels for huge wins.

Coin Win feature – this gives you a cash prize which is then subject to a random multiplier of between 15 and 30 times your stake.

Bonus Wheel feature – this bonus game can give you cash prizes and trigger the 2 free spins games described above (Sure Win Free Spins and Wild Reels Free Spins features). The Bonus Wheel is a 3 tiered wheel with 12 locations in each one – you 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.

If you reach the centre of the Bonus Wheel, you will get the Jackpot Coin Win symbol with a random multiplier value chosen – the minimum you will win is 25 times your stake and the maximum a whopping 1,000 times your stake (with 2 double ups).

As you can clearly see, Koi Princess has a lot of bonus features! The Bonus Wheel feature can give you the biggest wins in the game with a cool 1,000 times your stake but so can the Wild Reels Free Spins feature – this is the big wins will surely come from.

I found the variance to be somewhere in the middle which is good – NetEnt have created a good slot here but you need to be patient to land the right bonus feature to do well. If you like the theme, you should try Odobo’s Akaneiro which is graphically brilliant.
