Koi Harmony Review

Rarestone Gaming aren’t going to win any popularity contests anytime soon, but let’s be frank – not every studio has to have that superstar quality. And, to be honest, Rarestone Gaming have pleased us with many nice slots over the years. With Koi Harmony, they decided to go for something simple, yet elegant. When we say simple, we really mean it, as there are just 3 reels and 1 payline in this release!

Thematically, Koi Harmony is all about the famous koi fish, and the symbols are actually only about those. The background then shows a calm pond, which adds a fair bit to the atmosphere. The visuals are stunning, and we’re happy to applaud the designers for them, but the audio doesn’t really live up to expectations with its awfully basic sound effects.

Koi Harmony Slot – Reels Screen

Mathematically, Koi Harmony is a slot with a low-medium volatility level and a decent 888x jackpot. The least that you always have to play for is £0.10, but high rollers can risk as much as £500 per game round at select online casinos. The theoretical RTP of Koi Harmony is then 96.47%, which is way above average.

Koi Harmony Slot Features

Symbols work slightly differently than they usually do in Koi Harmony. You see, the symbols are all about koi fish parts. Your goal is to assemble an actual koi fish on the slot’s lone payline, though there are no guarantees that the symbols will align. If they do, though, you’ll get a payout that corresponds with the fish’s color. For a mixed fish, which is by far the most likely one, you’ll get 8x your bet. Then, there are purple, green, red, and yellow fish, which are worth 20x, 40x, 60x, and 100x your bet, respectively. Finally, you can also get the elusive rainbow fish, which is the slot’s jackpot and worth 888x your bet.

Koi Harmony Slot – Respin Feature Win Screen

There are no special symbols as such, but, if you get a combination that includes at least one rainbow fish segment, you’ll trigger the Respin feature. You’ll get one respin, in which all the symbols will have the same color (chosen at random) – your only goal is to assemble them properly and get a win.

Review Summary

Despite its simplicity, Koi Harmony is a visually appealing slot that is worth a spin for a single session. Chances are that one session will be more than enough, but the game certainly has its charm, and all winning combinations come with high payouts. If you’re in the market for simple slots, Koi Harmony will be right up your alley!
