Koi Princess consists of 5 reels, 3 rows, and 20 paylines, which cannot be changed, but the coin size can range from 1 cent to $1. With a maximum bet of $200, high rollers will also find it worth their while. In terms of symbols, NetEnt has drawn inspiration from the world of manga and incorporated many of them into the slot. On the left is the Koi Princess herself in an anime-inspired design, which is a unique feature for slot games. There is a wild symbol as well as a scatter symbol, and an auto-spin feature for players who prefer to watch instead of clicking constantly.


Those who enjoy manga will feel right at home with the multitude of extra features offered by this game. Moreover, the unique graphics and soundtrack add a special touch to this game. When a win occurs, the princess on the left side cheers and can perform even more actions when one of the bonus features is activated. If three or more bonus symbols appear on the reels, the reels move up slightly and the screen changes. The wild symbol is depicted as a wave and can substitute for all other symbols except for the scatter and bonus symbol. The bonus symbol, portrayed by the cheerful dragon, is the most visually striking symbol in the game, making this slot truly eye-catching overall.

Special Features

When it comes to special features, NetEnt once again outranks all other game developers and tempts players with extended rounds on the reels. Depending on how and where the symbols come to rest, different features are triggered in each case. The Random feature allows players to choose one of the options, meaning they can choose between three Koi carps that appear on the bottom screen.

One of them is the 5-Hit Random feature, which gives players 5 guaranteed symbols to win. A reel determines which symbol it will take. The 2nd feature is the random wild feature, where reels 2-5 become wild reels. In the 3rd feature, 4-9 more wild symbols are placed on the reels.

It continues with the bonus features, of which there is also a selection. The Sure-Win feature guarantees wins during the free spins, even if things don’t go quite so happily. During the first 5 free spins, players will get a further advantage on reels 1, 2 or 3 with Wild symbols added here, while the remaining 5 free spins will add Wilds on reels 3, 4 and 5.

The second bonus feature is called Wild Reels Free Spins Feature and consists of the aforementioned free spins with the additional wild symbols. Finally, there is the Coin Win Feature, which rewards the player with up to 30 times the bet payout. From here, you can be carried up a level to another wheel that pays out up to 100x winnings.
