Koi Princess Slot: Title review and impressions

5.4 

The online video gambling title Koi Princess has very distinct Asian and anime vibes to it. The main protagonist is a colorful young princess who will guide you through the experience. The game was definitely created with care, passion, and professional guidance. Everything, every tiny game detail is where it’s supposed to be in the Koi Princess slot. This creates an immersive adventure that will see you test your luck and revel in the visual and sound design. You can try the game for free to see if you like it or not or play for real money from the start.

The icons in the game look rich with color, crisp, and depict various Asian themes as well as the letters of the English alphabet. The symbols are statuettes of tigers, frogs and a bonus scatter icon of a dragon in Koi Princess. There’s also an icon of the girl herself which is one of the highest paying combos in the game. The wild icon within the game is represented by a crashing wave. It substitutes any symbol except, of course, the scatter and will pay you more than any other icon.

Koi Princess slot is adapted to various platforms and currencies so you can play online wherever you are and whatever device you feel more comfortable with. Koi Princess herself will cheer you on from the sidelines as you fight for the big win video and 250,000 units of the game’s currency, which is a stationary jackpot.

Overall Rating

6.4

Koi Princess is a slot machine with a multitude of extra content, games, and details. You will also find an RTP level of 96%, which is nice. And if by the end you will want to try another Asian-themed slot, Geisha Wonders will be happy to tend to your every need.

The random wild bonus in the Koi Princess slot machine will also give you a free spin + anywhere between 3 and 9 wilds as rewards
Another option will see you receive a free spin as well, but this time, during the spin, you will have an increased chance of wilds appearing on your second and fifth reels
Finally, you will receive a full bonus if you land at least 3 bonus icons. This feature in itself will present you with 4 additional play mechanisms within the base game. If you’re lucky enough to land this feature, you get to choose between 10 free spins with sure wins, 10 free spins with random wild reels, a wheel of fortune, and if you can’t be bothered by any of these - a simple coin reward.
