Koi Princess Online Slot Game — Evan Carrington Review | Casino Ideal
NetEnt has not generally been known for slots packed with bonus content, but Koi Princess takes a different approach. It brings together two Free Spins rounds, a bonus wheel, random Wilds and Wild reels, among other features. The Bonus Bet is presented as a way to improve players' chances of unlocking the full range.
Theme and Storyline
Koi Princess draws inspiration from Japanese anime and Asian pop culture. Its detailed presentation quickly becomes part of the appeal, with dragons, turtles, Chinese dollars and the charming Koi Princess appearing across the reels as players chase a big payout.
Graphics, sound and animations
As a NetEnt slot, Koi Princess offers polished visuals and sound. High-quality anime-style artwork, lively animation and an oriental soundtrack all reinforce the theme, giving the video slot a cohesive finish from the first reel to the last.

Top Casinos for Playing Koi Princess:
Gameplay
Koi Princess is a 5-reel, 25-fixed-payline video slot by NetEnt. Wins pay from left to right, and most combinations require at least 3 symbols. The Wild and Koi Princess symbols are exceptions, paying with just 2 symbols. Along with the dragon, turtle and Chinese dollars, these symbols offer the highest payouts.
The Wild substitutes for every other symbol to help complete winning combinations. The Bonus symbol is needed to trigger the bonus rounds.
Check the in-game paytable for the available combinations, bonus features and rules before playing.

Bonuses and free spins
Random Features: Four random features can appear while the reels spin in Koi Princess. They are:
- 5-Hit Random Feature: This feature is described as awarding a single free spin with a guaranteed five-symbol win.
- Random Wild Feature: This awards one free spin, with 4 to 9 additional Wild symbols placed on the reels.
- Wild Reels Feature: One free spin is awarded, with 2 to 5 reels converted entirely into Wild reels.
- Bonus Feature: When triggered, this opens the full bonus sequence described below.
Bonus Feature: The feature can arrive through the Random Features or by landing three Bonus symbols on reels 1, 3 or 5. In some cases, landing two of these symbols can nudge a third onto the reels. Once activated, spin the wheel beneath the reels to receive one of four bonus games:
- Sure Win Free Spins: The game description promises 10 Free Spins with a guaranteed win on each one. It also states that each win will be equal to or greater than the last.
- Wild Reels Free Spins: These 10 Free Spins randomly assign a number of fully Wild reels before each spin.
- Bonus Wheel: A single spin of the Bonus Wheel can award one of the two bonus rounds above or a coin payout.
- Coin Win: This outcome awards a coin payout.
Bonus Bet: The interface lets you switch the Bonus Bet on or off. It adds a bet equal to the total spin bet, increasing the stated chance of triggering random and bonus features. It also raises the rewards available from the Bonus Wheel and Sure Win Free Spins round.
Bet sizes, RTP and variance
Koi Princess has a wide betting range, from a minimum bet of 0.20 to a maximum of 200.00. Adjust your stake by selecting a coin level from 1 to 10, representing the number of coins wagered on each of the 20 fixed paylines. The coin value determines the worth of each coin, from 0.01 to 1.00.
Koi Princess has a stated RTP of 96.23% and is classified as medium variance. That classification may reflect its wide betting range and numerous bonus features, but does not indicate a guaranteed result.
Conclusion
Some slots look appealing but offer little depth; others have more to explore despite dated visuals. Evan Carrington's review presents Koi Princess as combining strong visual design, playability, big-win potential and a wide range of bonus features.
