Koi Princess is an oriental-themed online slot game which is packed full of mini games and bonus features. The game setting is an idyllic countryside location filled with waterholes and waterfalls, flowers, greenery and a Chinese temple. This quirky 5 reel game offers the chance of winning up to 100,000 coins.

The reels consist of theme-related icons and playing card symbols, which make up the lower value symbols. The higher value icons are the Koi Princess, the dragon, a turtle and Chinese coins. There is also a Wild symbol.

Koi Princess offers players a Bonus Bet feature for every spin. If the player chooses to activate a Bonus Bet, the spin cost will be doubled but the likelihood of being awarded a Random Feature as well as a Bonus Feature is much greater. The activated Bonus Bet also changes the Bonus Wheel values (more on this shortly) and maximises guaranteed coin wins in the Sure Win Free Spins feature.

There are four random features that can be triggered in Koi Princess:

5-Hit - this triggers 1 free spin featuring a sure win made up of 5 random icons on a random pay line.

Random Wilds Feature – this activates 1 free spin with overlay wilds (up to 9) landing randomly.

Wild Reels Feature – players are awarded one spin where 2-5 random reels are covered with just overlay wilds.

Bonus Activation Feature – this triggers 1 free spin where there are 3 bonus icons presented and one bonus game triggered at random.

This leads me on to the Koi Princess Bonus Features, where three bonus icons landing on the first, third and fifth reels triggers a random bonus. If you only land two bonus icons but you also have a winning bet line, there is a Nudge feature which could potentially result in a third bonus symbol nudging on to the reels.

The four Bonus Games include:

Sure Win Free Spins Bonus – this triggers 10 free spins, with the prize for each spin being at least equivalent to the greatest value won so far within the Sure Win Free Spins game.

Wild Reels Free Spins Bonus – this activates 10 free spins where each spin has between 1 and 5 random reels covered with Overlay wilds.

Bonus Wheel – this is a 3 tiered wheel enabling the player to click the dice to move around the wheel, winning coins and/or activating the other Bonus Feature Free Spins games.

Coin Win – this is simply an instant coin win.


This is a high quality and relatively complex game from NetEnt. If you love many mini features and bonus games to keep your game lively and exciting, then this is the slot for you.
