Lucky Koi Slot Review

What first came into your mind when being asked about Japan’s treasured animals? If I’m not wrong, then you were thinking about the Koi. The Koi, or Carp, symbolizes good luck, faithfulness, and perseverance in Japanese tradition. Bearing the same meaning, Lucky Koi, a casino game powered by Microgaming Provider, will ensure good fortunes coming your way. Have fun with our demo version and read through the rest of this review. Sometimes, thinking about trying this game with real money on top of online casinos to obtain more rewards and bonuses. Good luck!

A High RTP and Medium Variance Game

Below are some details about Lucky Koi’s technical aspects:

RTP and Variance: 96.47%, which is an acceptable rate for a casual slot game. However, it can go up to 97.5% during the Free Spins feature. The game has a medium variance, which means that there is a balance between the frequency of small wins and big wins.

Betting Range and Paylines: The betting latitude starts at 0.25 and scales up to 25 credits per spin. The number of paylines is fixed at 25

Highest Payout: Microgaming stated that this Asian-themed slot has a non-progressive jackpot of 125,000 credits. However, it can only be achievable in the bonus games.


  • The Scatter: Pays 4 times your stake for 5 icons on any payline
  • The Wild Lucky Koi: Pays 40 times your stake for 5 icons on any payline
  • The Koi: Pays 40 times your stake for 5 icons on any payline
  • Gold Nugget: Pays 16 times your stake for 5 icons on any payline
  • The Silver Nugget: Pays 12 times your stake for 5 icons on any payline
  • The Coins: Pays 10 times your stake for 5 icons on any payline
  • The Fan: Pays 8 times your stake for 5 icons on any payline
  • The Lily: Pays 8 times your stake for 5 icons on any payline
  • The Frog: Pays 8 times your stake for 5 icons on any payline
  • The Turtle: Pays 8 times your stake for 5 icons on any payline
  • The Dragonfly: Pays 6 times your stake for 5 icons on any payline

Apart from the Kois, all the other prizes are not too varied from one another. This will ensure a stable income for the players in the long run.

How to Win Big

Lucky Koi uses the common Wild feature, which is depicted as the title of the game hung above a golden koi. The Wild Koi can substitute all other regular symbols to form a winning combo. This online slot game also has its own payout, which is 40 times your total bet - the highest prize in the base game.

Go for the Spins or the Kois?

Lucky Koi has only one bonus, which is the Scatter. Three or more Scatters will trigger the Free Spins bonus. However, there are two Free Spins versions for you to choose from: either an ordinary one or a significant one. Let’s dig in further.

The Free Spins

Similar to the Free Spins versions in other slot games, you are given 10 to 30 spins and up to 5x multiplier at the beginning. Three Scatters will retrigger the Free Spins.

The Koi Bonus

Here comes the fun part. Naturally, players will go for the unusual bonus on their first Free Spins trigger. And Koi Bonus is an unusual one, whereas you have to pick from 3 to 6 Kois with an instant cash prize for each of them. Basically, it’s a Pick and Click game, disguised in the form of a Koi pond, very appealing in my opinion.

Goodness is Better Than Beauty

This five-reel online casino game has a standard Microgaming interface, with the options panel on the right side of the main screen, similar to the Kings of Cash slot. This slot game uses 2D graphics, with no 3D effects or any special animations in the base game. However, this 2014 title from Microgaming has a nicely designed Koi Bonus, with a pond full of Koi fishes in various shapes and sizes. There is no ambient soundtrack, only some audio when we trigger a win. Generally, I can say that this online slot is not a great game in terms of audio and graphics, so think twice if you prefer a good looking game to an exciting one.

The Final Thought

All in all, Microgaming did put some effort into making the Lucky Koi online slot game, but I don’t think that’s enough. The graphics are unappealing, the audio is plain and boring while the bonuses are not that special at all. However, if you love Japan and their interesting cultures, don’t miss out on this slot because who knows, you may be the one that is blessed with good fortune among us gamblers.
