Koi Princess slot is unlike the rest of NetEnt’s video slot releases. This 5 reel, 20 payline slot is packed with lots of bonus features like base game bonuses and random mini-games that that will keep you entertained. For this release, the Swedish online slots wizards have found inspiration in the world of Japanese animation known as anime. Everything in this online slot is on-theme and designed with the anime twist or presenting certain element of the Japanese culture.

Koi Princess Overview

As stated above, everything in Koi Princess slot is designed with Anime in mind. The overall design of the game is not that complex, but the subtle effects make for a noteworthy visual experience. The reel set is set against a background of mountains with an ancient temple on the left and a mighty waterfall on the right. The reels are placed inside a frame of traditional Japanese ornaments with the game’s protagonist, the Koi Princess, on the left.

There are two types of symbols on the reels of Koi Princess slots, low value symbols and high value symbols, all designed with a certain anime twist or representing elements of the Japanese culture. The low-value set of symbols consists of five standard playing card symbols all designed to look as lucky charms. These symbols comprise 10, J, Q, K, and A, in ascending order, and their payout values depend on how many matching symbols, 3, 4 or, 5, are landed on the reels.

The high-value symbols in the game are five game specific symbols that award players with certain amounts. Three of these symbols, the lucky charms, the turtle, and the dragon, have payout values for landing combinations of 3, 4, and 5 matching symbols, while the game’s highest paying symbols, the Koi Princess and the Wild symbol, award payouts for landing combinations of 2, 3, 4, and 5 matching symbols.

The Wild symbol is a stylized representation of the famous woodblock print The Great Wave off Kanagawa with WILD written on the top.

How to Play Koi Princess

Since the 20 paylines of Koi Princess slots are fixed and cannot be adjusted, the only two things that need to be set before the spinning of the reels are the Bet Level and the Coin Size. The game has 10 different bet levels, each represented by 20 coins. You can set the Bet Level by pressing the green arrow buttons on the sides of the LEVEL box.

The final thing to set for the total stake is the Coin Value and in this video slot there are 7 coin-values to choose from: 0.01, 0.02, 0.05, 0.10, 0.20, 0.50, and 1.00. By pressing the green arrow buttons on the sides of the COIN VALUE box, you can select the Coin Value. By combining the Coin Value and Bet Level, you get the limits for the game’s minimum and maximum bets which are 0.20 and 200, respectively. To set off the reels and start playing, you need to press the Spin button, the round green button in the bottom centre of the screen.

The remaining two buttons on the sides of the Spin button are the AUTOPLAY feature and the MAX BET feature. The latter enables players to spin the reels with the maximum bet level for the selected Coin Value, while the former lets you play a certain number of spins automatically. To activate the AUTO PLAY feature, click on the AUTOPLAY button, and immediately you will be taken to a new window where you can set the number of spins and other additional settings. When you make your selection, the reels start spinning and the remaining number of spins is displayed. To turn off this feature, you need to press the STOP button.
