Although NetEnt online slots are not usually associated with lots of additional bonus features, Koi Princess slots is one of the exceptions. This oriental-themed release is a five-reel and 20 fixed payline online slot with a familiar theme, but with a certain manga twist which makes it stand out from the crowd. Koi Princess bonus features include Bonus Bet, Random Features, Bonus feature, and mini-games, which should be more than enough to keep everyone busy.


As with most video slots, the reels of Koi Princess slot are decked with two groups of symbols. The low-value symbols are 10, J, Q, K, and A, while the game’s four high-value symbols include lucky coins, a turtle, a dragon, and the Koi Princess logo.

The game makes use of additional special symbols that include a breaking wave Wild symbol and the bonus symbol is represented by a golden dragon’s head.


As stated in the previous sections, Koi Princess bonus features include the following features:

Bonus Bet

The first of the Koi Princess bonus features is an optional extra which will cost you double your current bet. This bonus bet will increase your chances of triggering the random features and the bonus feature, and it will increase the payouts in the bonus game.

Random Features

These features can be triggered on any spin from the base game and players will be offered three Koi to choose from. The following four bonus games are offered by them:

  • 5-Hit Random Feature – a free spin with a guaranteed win of five symbols
  • Random Wild Feature – a free spin with 4 – 9 extra wilds on the reels
  • Wild Reels Feature – a free spin with 2 – 5 reels completely wild
  • Bonus Feature – this activates the full bonus

Bonus Feature

The Bonus Feature is triggered by landing three bonus symbols anywhere on reels one, three and five, or by picking it from the Random Feature. If you land two bonus symbols you may get lucky and see a third ‘nudged’ onto the reels.
