Lucky Koi Online Slot Machine

The video slot Lucky Koi was the first release of the year 2014 by Microgaming, which went live on the 7th of January. With a calm, pleasant Japanese koi pond theme rendered in vivid graphics, it has been much popular as one of the most beautifully designed slots of the Oriental genre. A contemporary 5-reel and 3-row slot machine is played over 25-paylines and features wilds, scatter and the Lucky Koi bonus game. And to top it all, the massive jackpot can win you up to $125,000 against a max bet of $25.

Main Characteristics of the Lucky Koi Slot Machine

Koi is a variety of Amur Carp that is treated as ornamental fish in the traditional Chinese and Japanese culture and is highly regarded as a symbol of good luck and fortune. The beautiful koi ponds with crystal clear water and lots of colourful fish are largely used in Japanese gardening and aesthetics that have deeper applications for physical and mental wellbeing. 

In the Lucky Koi slot game, the aesthetics are radically one of the main characteristics. The aquatic blue background appears like the surface of the pond, while the transparent reel seems floating on the water. Animate aquatic creatures are the main game symbols - koi fishes, green turtles, dragonflies, frogs and lotus flowers that swim across the screen and create a jovial, pleasant ambience altogether.


The Substitution Wild symbol bears the game title and a golden koi emblem. This symbol mimics other symbols on adjacent reels, thus it is capable of completing a winning streak if it lands in the right spot at the right time. And, the koi Wild, which is also the highest paying symbol in this game, also comes with its own value worth up to 1000 credits.


Technically, the Scatter is also a base game feature, but since in most games its main purpose is to activate the Free Spins rounds, it has nothing to offer as a base game win. However, in the Lucky Koi slot machine game, the scatter also has a cash value. So landing 3, 4 and 5 symbols with the temple and windmill picture will give you two choices of bonus games, plus a payout of up to 100 credits, based on how many scatters you got and what the size of your bet is.

Bonus Games 

The scatters make way to two different bonuses, and you got to choose any of them. 

  • Free Spins - get anywhere between 10 and 30 free spins, plus a random multiplier of up to x5, that will apply to all wins during the free spins round. 
  • Lucky Koi Bonus - this choice takes you on a fishing game in a separate window, where several colourful koi fishes swim across the screen. You are given a random limit of how many fish you can pick from the pond, ranging from 3 to 6. Use a virtual fishing pole to pick as many koi fishes. Each fish comes with a hidden amount of the cash prize, or you can also unlock additional picks. 

That’s about it, the special features in this game - there are just two of them but trust the experts, this is too much. You can fish out handsome wins through the free spin rounds. 

How to Play the Lucky Koi Slot Online 

The gameplay is so simple and somewhat tranquil that makes it ideal for new punters. All you have to do is adjust your bets and hit the spin button.

The betting limits range from a minimum of $0.25 to the Max Bet of $25. So you can keep up with a long-running gaming session, even with low-key deposits of $50-$100. 

There is the Autoplay option, but it doesn’t have advanced settings. The Turbo button is the small round icon above the main spin button, this feature speeds up the spin. 

Built on an instant play platform, this is a no download slot that you can only access via browsers. There is no option to download the Lucky Koi slot machine online, but it is featured in downloadable casino apps. To judge how the game behaves with your mobile, open the Lucky Koi demo game on your device. 

How to Unlock the Hidden Fortune in the Koi Pond

The best way to win this game is to give it some patience. The variance is high-to-medium,  so you can land decent wins at short intervals, but you got to give it a good deal of time to land the bonus games - that’s where all the action happens.

So, even though Lucky Koi has a 96.47% payout rate (RTP), the base game is too uneventful in terms of payouts. While you can take this as a standard low-roller game, the highest base game winning streak you can get is 40o credits, which is not bad, but it doesn’t occur too easily. The maximum you can win at this game is $125,000, which is only possible through bonus games.

For best insight, it is highly recommended that you try out Lucky Koi for free before going to play Lucky Koi for real money.  


Lucky Koi hits all the right notes on game design that is immersive and soothing to the core, which is also quite fair about its payout arrangements. But all together, you are up against just one bonus feature - the scatter, with generally high volatility. So until the scatter unlocks the bonus games, the calming and soothing elements may be translated as uneventful for players used to gambling at a fast pace.

This game is designed to give punters a low-key, low-budget gaming experience that can, by chance, unlock a lump sum of a cash prize. That is what makes this slot worth your time and money. We invite you to play free Lucky Koi casino slot machine right here on our site, to have hands-on experience about the game payouts.
