Rainbow Burst Features

This 5x3 set of reels only presents 10 win lines, so you will need the luck of the Irish to land a prize. A minimum of two matching symbols are needed to create a win thanks to the pint of stout but all other symbols will require a group of three. The highest payers are the stout, horseshoe, harp and shamrock. the lowest payers are 10 through to ace.

There is also a Wild symbol available and this is represented by a large 'W'. These will substitute for all others except for Bonus symbols, Rainbow symbols and the Collect symbol.

Special Features

It won't come as a complete surprise to hear that rainbows feature heavily in this Irish-themed slot. Up first, we have Rainbow symbols and these are simply gold coins that offer a value of up to 1,000x, but you'll only see them on the central 3 reels. you can't do anything with these coins unless a Collect symbol lands on the 5th reel.

These symbols always come as a stack of 3 but they won't always be completely visible on the reels. When they are, a couple of special things will occur. Firstly, you get a respin and the leprechaun acquires a large pot of gold. If a Collect symbol lands, then you win any values on the reels and cash that has been added to the leprechaun's pot.

Secondly, a rainbow is added to one of the chests below and this will load up the meter and trigger one of three jackpot prizes worth up to 5,000x.

It is also possible to play for free thanks to the Free Spins Bonus. This can happen when a Free Spins Bonus Symbol drops on the first reel and a Collect symbol lands on reel number 5. Up to 16 Free Spins are awarded and Rainbow symbol stacks will grow by +1 with each spin. It is also possible to retrigger these free spins and remember that the Golden Chest is in play during the bonus round. This means that jackpot prizes are bigger than during the base game.

Rainbow Symbols

These coins feature a value of between 1x and 1,000x and can only land on reels 2, 3 and 4. If a Collect symbol drops onto reel 5 when Rainbow symbols are present, then you win their values.

Rainbow Burst - Rainbow Respin

Rainbow Respin

When Rainbow symbols stack to cover an entire reel, you’ll get a respin. If a Collect symbol lands, you’ll win the contents of the leprechaun’s pot.

Free Spins Bonus

A Free Spins Bonus symbol on reel 1 plus a Collect symbol on reel 5 means a reward of 8–16 free plays. Rainbow symbol stacks now grow by +1 with each spin.

When Rainbow symbols stack to cover the reels, you also get a rainbow added to the Iron and Golden Chests. This might eventually trigger a Rainbow Burst with 1 of the 3 jackpots now guaranteed.

Rainbow Burst Review

I'm going to say it straight off the bat, I do not trust this creepy-looking leprechaun as far as I could throw him. He looks sinister and that's putting it mildly. However, he does seem to be in charge of dishing out a good amount of gold coins and that's all that really matters, I guess. Hopefully, you'll make your way to the end of the rainbow and take everything he's got before running away as fast as you possibly can!

Design

My little leprechaun friend dances away to some typically upbeat Celtic music and even though I don't care for this creature, he is cutting some amusing shapes up there on the top of this hill. 

The rainbow extends across the reels and the 2 chests are always enticing as they begin to fill up with each blast of the rainbow. It is entirely stereotypical but Rainbow Burst is a good-looking game that produces some decent visual effects on all devices, including mobile phones.

Gameplay

There’s enough going on during the base game to keep you more than satisfied while you hit the spin button—the stacks of Rainbow symbols plus the chance to trigger one of those jackpots should do the trick. The additional respin, which can come with a few extra quid courtesy of the leprechaun’s pot, is also a welcome add-on. Obviously, the bigger wins are more readily available throughout the bonus game thanks to the increasing stacks of Rainbow symbols and the much larger jackpot prizes.

Win Potential

Some lucky players might be able to achieve the top 5,000x payout that Rainbow Burst has to offer. The medium volatility came as a bit of a surprise and the max 96.15% RTP isn't bad either. However, you should check out this figure before you play as it can go as low as 86.90% in some places.

Our Verdict

Admittedly, I approached Rainbow Burst with a certain amount of scepticism. We've been here a million times before with Irish-themed slots and I was pretty sure that my heart would sink with the first touch of the spin button. However, my fears were unfounded and Nailed It Games has done a fine job. It won't get top marks as the design just isn't quite there and the max payout is a little small to be a contender for a top slot. But don't let those things put you off though as you can still enjoy a decent session with this game.
