Koi Princess slot – NetEnt


Koi Princess reviewTravel to the mountains to meet the Koi Princess in this graphically stunning, online slot. Since its release in November, 2015 by NetEnt, this Koi Princess slot has enjoyed its fair share of popularity with its eye catching Anime inspired graphics, entertaining Bonus/Random Features, Bonus Bet Mode, RTP of 96% and the tempting promise of winning up to £200.000! To quote the award winning slot creators, “Koi Princess is the most feature-packed slot we have ever made!” For those of you that love plenty of bells and whistles in slots, this may just be the perfect match.

Meet the Koi Princess

Anime/Manga fans will love the animations of Koi Princess, a 3-row, 5-reel, 20-fixed payline online slot that is set against a mountainous background with a glimpse of a royal palace to one side and a rushing animated waterfall to the other. The Koi Princess herself is just left of the reels which are framed against a scroll with pink cherry blossom accents. Spin for cash to the soothing tones of an orchestra playing traditional Asian music. Like many other NetEnt slots, Koi Princess is playable online from either mobile device (iOS; Android) or desktop.

Koi Princess Cash Bets can be selected by adjusting the Coin Value and Bet Level. There are 7 Coin Values (0.01, 0.02, 0.05, 0.10, 0.20, 0.50, 1.00) and 10 Bet Levels (1-10). The slot’s Bonus Bet Feature directly affects the Cash Bet range. If the Bonus Bet feature is deactivated, the Cash Bet range is 20p-£200 at the online casino Karamba. If it is activated, the Cash Bet range doubles to 40p-£400. That gives the game a flexible, overall Cash Bet range of 20p-£400, suitable to most budgets and competitive among other online slots of its kind. Keep track of cash easily along the bottom of the screen during gameplay.

Wild Win Koi PrincessKoi Princess pays out left to right only starting from reel 1, and multiple wins on different paylines from a spin can be added together into a lump sum. To calculate your win from coins into cash, simply multiply the Coin Value of the bet by the Coin Win. For example, if a minimum Cash Bet of 20p (Coin Value of 0.01) is selected and a spin yields a single payline win of 5 Wilds (Symbol Coin Value of 500 coins), then the total Cash Win would be calculated as follows: 0.01 x 500 = £5. That amounts to 25x the base Cash Bet. Fortunately, the game auto calculates Coin Wins to cash along the bottom of the screen beside Cash Balance and Bet.

This slot features 2 special symbols: a Wild symbol (replaces any except the Bonus symbol) and a Scatter Dragon Bonus symbol (only appears on reels 1, 3, and 5). The Wild is the highest value symbol. There are 9 regular symbols with the Koi Princess, Lion, Toad, and Lucky Coins as the higher value symbols and 10-Ace as the lower value symbols.

Special features
Koi Princess’ Auto play ranges from 10-1.000 automatic spins. Advanced settings allow slot players to set it to stop: on any regular, Bonus Feature, or Random Feature win, if a single win is more than a set amount, or if cash balance increases or decreases by a set amount. Special game settings include Quick Spin and the option to set the spacebar to spin if playing from a desktop.

Koi Princess Bonus and Random Features

Bonus Bet Mode: While bets are double the expense, it is much more likely that a Random or Bonus feature will be awarded if this is activated. Not to mention, the RTP goes from 96% to 96,23%, giving players a slight advantage.
Bonus Features: A spin yielding 3+ Scatter Dragon Bonus symbols will trigger the appearance of a Bonus Wheel. If a spin yields a win and 2 dragons, the game throws us a bone by “nudging” a 3rd dragon to make the Bonus Wheel appear. Players must hit the green stop button to stop the wheel thereby randomly selecting 1 of 4 Bonus Features.

Sure Win Free SpinsGet at least 10 Sure Win Free Spins featuring overlay and random Wilds. The highest win is the Sure Win which is applied to all Free Spin Wins.


Wild Reels Free SpinsGet no more than 10 Wild Reels Free Spins. Enjoy the benefit of 1-5 reels covered in overlay Wilds.


Bonus WheelThe Bonus Wheel Bonus Game involves a wheel and dice. Play for a Coin Win, Jackpot Coin Win, possible activation of Sure Win Free Spins & Wild Reels Free Spins, Double Up the bet, or win 1x-5x the bet. The Jackpot Coin Win multiplier ranges from 25x-250x the bet for a potentially huge coin win!

Instant Coin WinGet an instant coin win amounting to 10x-30x the bet.


Random Features: Any win can trigger Random Feature selection. Pick a koi to be randomly awarded 1 of 4 features: 5-Hit, Random Wilds, Wild Reels and Bonus Activation. Each will last for 1 spin.

5-hit featureThe 5-Hit Feature guarantees an automatic win with 5 matching symbols. The winning symbol is randomly selected.
