My Summary & Rating of Koi Princess

Even though my test run resulted in a loss, the experience was fun nonetheless. I thoroughly enjoyed the element of randomness and frequent diversions from the base game. Whereas many slots have a bonus game, this one offers 8 bonus games that are random and triggered. You won’t get bored playing the Koi Princess slot for free or real money. Here at SlotsUp, we follow a strict formula for rating slot games. After assessing all the angles, I have assigned the free Koi Princess slot a 72 out of 100 rating. It would have scored higher if the maximum payout was higher. I recommend trying Koi Princess, even if the anime theme isn’t your thing. The multiple features build a lot of anticipation with every spin and make the game more engaging than most modern slots.

  • Loads of features

  • Flexible bet range suits most budgets

  • Two free spins features

  • The anime theme isn’t for everyone

  • Low maximum payout

  • Slightly dated graphics

According to my test and analyze I give a rating of 100 rating out of 100.

Game Review policy

Koi Princess by NetEnt is a 5X3 slot with 20 paylines and nine exciting bonus features, including free spins, Bonus Bet, and Random Wilds. The Koi Princess RTP is 96.23%, and players can win up to 1000X their bet. The Koi Princess free slot’s release date was November 24, 2015. It was NetEnt’s first game to offer an anime theme.

Koi Princess volatility is rated medium, which means you can expect to haul in some impressive payouts mixed in with a few cold streaks. This free slot machine is suitable for most budgets because the bet size ranges between $0.20 and $200 per payline. The Koi Princess demo slot is ideal for anime fans who want access to many bonus features.

Free Koi Princess Slot Mechanics

Koi Princess’ game mechanics are pretty basic. The base game is played on a standard 5X3 grid that offers 20 Koi Princess paylines. In addition to the traditional playing card symbols, the game features a Wild, the Koi Princess, a frog, a dragon, and a coin symbol. It also has 4 random bonus Koi Princess symbols, two free spins symbols, a Bonus Wheel symbol, and a Coin Win symbol.

While the free Koi Princess slot doesn’t offer modern game mechanics like Megaways or Cluster Pays, it’s essential to understand that the multiple features more than make up for that.

Koi Princess Features and Gameplay

Let’s start by taking a look at the Koi Princess paytable. The low-value symbols include the 10, J, Q, K, and A, which pay between .25X and 8X when you land between 3 and 5 identical symbols on a payline. The higher value symbols include the coins, the frog, and the dragon, which return up to 300X your bet when you land 3, 4, or 5 of them. You only need to land a minimum of 2 Koi Princess or Wilds to score a payout ranging from 2X up to 500X your stake.

Three koi will randomly appear at the bottom of the reels when you play Koi Princess for free or real money. You then select one of them to trigger one of the random bonus features, which are:

  • Random Wild — you will get a free spin with between 4 and 9 extra Wilds.

  • Wild Reels — get a free spin that will produce between 2 and 5 Stacked Wilds.

  • 5-Hit — spin a bonus wheel at the bottom of the playing area, guaranteeing you hit at least one five-of-a-kind.

  • Bonus Trigger — land 3 dragon bonus icons to trigger the Scatter Bonus feature.

Then there are the triggered bonus features, which are:

  • Sure Win Free Spins — get 10 free spins guaranteed to all pay.

  • Wild Reels Free Spins — win 10 Wild Reels Free Spins with each round guaranteeing that Wild symbols will cover between 1 and 5 random reels.

  • Coin Win — awards the player an instant coin win.

  • Bonus Wheel — a bonus game incorporating Wild Reels Free Spins and Sure Win Free Spins. This bonus feature offers the Koi Princess a maximum win of 1000X your total bet.

Finally, the Koi Princess free slot has a Bonus Bet feature. When activated, your stake amount will be doubled, but it will also increase your chances of triggering a bonus feature while changing the values on the Bonus Wheel and increasing the value of the Sure Win Free Spins feature. Players are better off having the Bonus Bet feature activated at all times, even if this strategy can be more expensive.

Koi Princess Maximum Win Potential

Koi Princess

Your bet size can be anywhere between $0.20 and $200. With the maximum big win set at 1000X, the most you can win is between $200 and $200,000. You can only achieve the 1000X payout through the Bonus Wheel bonus game. The maximum win for the base game is between $100 and $100,000, depending on your bet size.

A 100-Round Excursion with the Free Koi Princess Slot

I wanted to play Koi Princess in demo mode for 100 spins. I started with a 5,000-coin bankroll and set my stake at 20 coins per pull. As an aside, I didn’t activate the Bonus Bet feature for the first 50 spins. And speaking of those first 50 spins, I hit payouts on 19 of them. Unfortunately, they were primarily minimum wins except for the 660 coins I hauled after randomly triggering the Bonus Wheel. My balance at the half was 5059 coins.

I proceeded to activate the Bonus Bet feature for the second set of 50 spins, which upped the cost of each spin to 40 coins. I landed 16 total wins, including a 400-coin Coin win and a 951-coin Random Wilds win. However, the other wins were small, and I ended the 100-round test run with 4751 coins for a net loss of 249 coins.
