Lucky Koi is Microgaming powered video slot with 5 reels and 25 pay-lines. This slot is inspired with Oriental culture and symbols. The animations and graphics are amazing, and there’s a nice soundtrack that goes along with it. The reels are transparent, and are set against the moving watery background.

Before you hit the reels, you should set your bets. By clicking on "Bet" you can set coins size, the number of coins per line and lines. "Coins Size" button will set coins denomination which ranges from 0.01 to 0.10, and "Coins" is used to set the number of coins per line that you wish to bet, and "Lines" will set the number of lines. "Spin" will set the reels in motion, and "Autoplay" option is used to turn the reels without interruption for a chosen number of times.

The Lucky Koi is the Wild symbol, and it can form its own winning combos. This Wild symbol can substitute all symbols except for the Scatter. The Scatter symbol can form scatter wins, and once you hit 3 or more of them anywhere on the reels you will trigger the bonus choice. You can choose between Free Spins and Koi Bonus feature.

Honestly speaking, I like games that has fishes for its theme, not so much for the deep ocean kind , but more of the rearing kind, that swims in beautiful ponds or breeding places. like in this Lucky Koi game. I used to admire these fishes ever since I was a boy, at times putting my nose up against the aquarium glass to have a good insight of how it feels like being in the water, at times even imagining myself to be one of the fishes. Swimming so freely, without a care in the world, unlike in the human world. I love being a free spirit, free from anything that binds me to this materialistic world, of which I'm only beginning to enjoy now, but can never be as free as those fishes.

I like those Koi fishes. The tortoises and the dragon flies are okay too, but frogs don't excite me at all. The symbols in this game is a mixture of likes and dislikes for me, but that distracting pebbles background when spinning the reels is not to my liking at all. A moving water background with blurry plants and corals would have been perfect, but Microgaming guys think otherwise. That background spoiled my overall impressions of the game. The logo 'Lucky Koi' is the Wild symbol, 5 of which pays 40x the total bet, which is extremely low for a 25 paylines game, and is also a dumb Wild symbol too. Sheesh! No paying for itself, no doubling of wins, no expanding, no stacking, just the usual substituting, and that is very disappointing.

The Scatter symbol pays 100x the total bet for 5 of them, and getting 3 or more of these Scatters trigger a Bonus Choice, either a Free Spins game of 10 up to 30 free spins, with up to 5x multiplier, all randomly awarded, or the Koi Bonus game, whereby you pick 3 - 6 fishes to win prizes, with a chance for one extra pick. More free spins can be retriggered, but not for the Koi Bonus game, so the paytable says. The Koi fish pays 40x, the Gold Ingot pays 16x, the Silver Ingot pays 12x, the Bronze Coins pay 10x, and the rest paying from 8x to 6x, all per total bet amount for 5 of each kind. Sadly though, a very low paytable.


The low paytable should be able to provide an extended enjoyable playing time, but this wasn't exactly the case with this Lucky Koi game. At times, the game plays well, at other times, it can eat your credits quite fast with numerous low-paying and non-paying spins. Both the Free Spins game and the Koi Bonus fishing game can pay out some decent but mediocre size wins, of which the best I could get was just around the 50x total bet amount. Nothing higher than that so far. With better luck, better wins could be possible, but I ain't gonna try for it. It's an acceptable game to play, but not for big-win hunters.

Lucky Koi is a very interesting and pleasant video slot to play. This is a 5 reels 25 pay lines video slot from Microgaming software. The graphics are really nice and the sound effects are soothing. The theme of this slot has to do something with China, because there is a Chinese vibe in this slot. This game features scatters and wilds and it has 2 bonus rounds, the free spins of course and the Koi bonus. This game is great because it is very easy to trigger these features and then you have to choose which one you want to play.

You have to choose your bonus between 10 free spins with a random multiplier or a koi bonus. I have chosen the koi bonus the first time, because this is the unique bonus for this game. Then, you have to pick 6 koi fish. They are all in a pond and you have to take them with a fish rod, and each one hides a cash prize. Some of them were hiding more some of them were hiding less coins. The last fish that I picked gave me an extra pick so I ended the bonus with 46 euro plus on my balance. Not a bad choice I must admit. It took me a while to trigger the bonus round again. This time I chose the 10 free spins. I got x 3 multiplier and I got 31.40 only this time. I have been triggering the bonus very often during my long session and later I was always picking the koi bonus. The most that I have got from this bonus was 100 x bet. It is not that impressive but it was good enough to keep me busy.

I have to say that there is no doubt that this game has a very big potential. I will definitely play this slot again and I would suggest the same to anyone who has not tried it yet.

Lucky Koi game is made by Microgaming software provider. I think it is very good game honestly. They made a pretty and relaxing theme for this slot and I enjoyed playing it.
Next thing what I really liked in this game was this Japanese motive. I like this game because I got the bonus round on this game many times.

An nice thing with this game is that when we get to 3 scatters that are represented by a stone lantern, it will award you a win and also you will have a possibility to choose the Free Spins feature or the koi bonus.

I don’t know how work this koi bonus, I did choose non stop the free spins because I like free spins more than the bonus games.

My best win at this game is 32 euro in the free spins feature and 5 euro in main game. This game boosted my account balance to 56 euro with deposit of 20E. This time I requested a cash-out because I feel happy with it.

In my personal experience, I can rate 8 stars for the pretty graphics and for this traditional Japanese style and that is very good design which is suited very nice with this kind of slot game. The payouts I should say that is very good, I won some nice cash very easy, I played only about 1 hour, I had many fun and I think it deserves 8 for this.

In last words I can say that it is a very good video slot,and I think it deserves a place in the top of my favorites slots that I played so far. I am rather sure that I will play soon this slot again and I hope I will win something even bigger. I can recommend you all who like Japanese culture to play in that video slot also if you want to have some free time.


Well I don't know what to really mention here but i must have write something here.
