Review of Lucky Koi's Key Features
Great animation and two top bonus features

The Lucky Koi online slot is more of a leisurely walk in the park than a sprint to the finish line. Everything about this Eastern themed slot, centred around a koi pond, is gentle and relaxing, from the calming soundtrack to the rate the invisible reels spin. Even the animation, when it occurs, is sweet natured.

You can bet from just 1p a line here, all the way through to a max bet of £125 a spin, so low and high limit players will find stakes to satisfy their bankroll. Plus, there's a free spins feature where players can earn up to to 5x on wins, and a bonus game where cash can be hooked simply by picking the right koi fish at random.

It's the koi fish symbol that pays the most in the Lucky Koi online slot

If you want to see the biggest returns on the reels then landing 5 x koi fish is the combination you should hope to net (no pun intended). After this it's the gold and silver ornaments, followed by the fan and lotus. The lowest paying reel symbols are the frog, turtle and dragonfly.

Land 3 or more scatters and you earn a bonus reward

There are two bonuses up for grabs throughout the Lucky Koi slot machine, both of which are unlocked by landing 3 (or more) scatters on the game's invisible reels. When this occurs you'll be presented with a screen asking you to select your bonus, including the free spins feature.

Choosing this bonus will award between 10-30 Free Spins, subject to the number of scatters that triggered the feature. You'll also enjoy a multiplier up to x5 on any wins you make while the feature is active. And three or more scatters will automatically retrigger the feature again.

The second bonus in Lucky Koi slot is a point and click game

The other bonus up for grabs when you match 3 or more scatters in Lucky Koi is the Koi Bonus Game. This is a side game that takes place away from the reels.

Your job here is to pick 3-6 Koi fish at random (again the actual amount depends on how many scatters you landed), but you'll always have a maximum of 12 fish to choose from. Every one awards a random cash amount, which totals when you've made all of your selections.

The Wild in Lucky Koi replaces all symbols bar the scatter

Another lucrative reel symbol in Lucky Koi is the Wild, which in this case is the game's logo. When the wild appears on the reels at random it can substitute for any other symbol, giving players a chance to make instant matches across the active paylines they have in play.

The only symbol the wild can't replace is the scatter, so there's no danger of blowing your shot at a bonus if the wild does appear. In fact, in free spins, the wild changes to an expanding wild, opening up the possibility of even more lucrative payline wins.

Graphically impressive but might be a little sweet for some slots fans

We certainly can't pick fault with the aesthetics Microgaming have produced in Lucky Koi. Visually speaking the slot looks fantastic, and the animated symbols are a nice touch when wins kick in.

But the theme of a Koi pond might be a little too nice for some slots fans to stomach. It certainly doesn't have the pace of some action and adventure slots we've played. After only a short time we found ourselves muting the game's looping soundtrack.

But, we did enjoy the two bonus features offered at Lucky Koi none the less. So if you're looking for a slot that's a little less intense, but still with some nice features, this one might tick the box.
