Japanese anime meets slot reels on Koi Princess from Swedish game studio NetEnt. A serene appearance is combined with a flurry of four random and four bonus features. Lucky Koi fish will come to your aid, helping you to score wins of up to 500 times your bet in a single spin or 1,000 times your bet on the Bonus Wheel.
Koi Princess is a video slot with five reels, three rows and 20 fixed pay lines. Wins are paid for three to five matching symbols on a line from left to right only. The fishing expedition on desktop or mobile starts at 0.20 credits and peaks at 200 credits per spin. It will increase to 0.40 to 400 credits when the Bonus Bet is activated. The RTP of this low variance game is set at 96.23%.
Set in a serene valley with an Asian temple and a waterfall in the background, the semi-translucent game window impresses with intricate pay symbols and elaborate animations. The anime princess stands on the left of the game window, going into a girlie giggle on winning spins. An equally serene Asian soundtrack completes the slot design.
The pay symbols start at the low end with the card royals from 10 through to A, awarding 5x to 8x your stake for a single five of a kind. They are followed by lucky coins, lucky toads, lucky lions and the Koi Princess at the high level. Hit five on a lien to win 10x to 20x your bet. Only the princess symbol appears stacked at all times.
An intricate icon marked with the word itself is the wild symbol, appearing on all reels and substituting for all regular pay symbols. A single five of a kind will pay 25x your stake. A dragon icon marked with “Bonus” is the scatter symbol, appearing on reels one, three and five only.
Koi Princess Slot Features
The first thing you will need to decide is whether you want to activate the Bonus Bet option on the slot. It doubles the cost per spin and increases the frequency of the random and bonus features as well as the coin wins on the bonus wheels.
The suspense and action in the base game are provided by no less than four random features which can trigger at the start. Three Koi fish will appear in front of the game window, allowing you to make one pick to display the awarded feature.
- Guaranteed 5-Hit: The reels will spin and will stop guaranteed a five of a kind of a randomly chosen pay symbol.
- Random Wilds: The game will place four to nine wilds on random reel positions
- Wild Reels: Two to five reels turn wild. A full screen will award the maximum win in one spin at 500x your bet.
- Bonus Activation: The spin will land guaranteed three scatters to trigger one bonus feature

Prepare for more action as NetEnt included also four bonus features on this slot which will be randomly awarded from the Bonus Feature Wheel. Hitting scatters on reels one, three and five will activate the wheel. There is a random chance that the third scatter will be nudged into view when only two scatters land. Alternatively, it can be won in the random feature. You will get one spin on the wheel to determine which bonus feature will be awarded.
- Coin Win: The least desirable option, paying a random coin win between 10x to 30x your bet
- Bonus Wheel: A 3-tiered wheel with coin wins, double-up, advance arrows, two free spin features and collect. Spin as many times until you hit either collect, win a bonus feature or reach the centre of the wheel. Reaching the middle can award an extra pay of up to 1,000x your bet.
- Sure Win Free Spins: Awards 10 free spins which cannot be retriggered but hitting a win higher than the guaranteed win will add +1 free spin. The game guarantees a win on every free spin which is equal to the highest win from any previous free spins. On the first free spin, the guaranteed win is equal to the amount staked.
- Wild Reel Free Spins: Awards 10 free spins which cannot be retriggered. On every free spin, one to five reels will be randomly chosen to turn wild.
Koi Princess was at the time of its release in 2015 the most feature-rich slot that NetEnt released up to then. Four random features and four bonus features attracted recreational and hardcore players alike. While the win potential is not sky-high, the game has ample chances to hit wins in the 100x to 500x range.
