3 Lucky Rainbows

by SpinPlay Games

If one free spins bonus round isn’t enough for you, then take a look at 3 Lucky Rainbows. Each rainbow comes with its own pot of gold, in the form of a free spins bonus round, - and they all come with their own modifiers.

Multipliers, nudging Wilds and four fixed jackpot prizes add to the fun. And with a top payout worth 5,000x your stake, the potential rewards make this a slot worthy of further investigation.

3 Lucky Rainbows Features

If you love nothing better than a free spins bonus served up with your slots gameplay, then look no further than 3 Lucky Rainbows. The theme may be whimsical, but the game is packed with not one, not two – but three free spins bonus features. And each one comes with its own exciting gaming mechanic that could add plenty of extra value to payouts.

Whenever one or more lucky coins appear, there is the chance for Pot of Gold free spins to be collected depending on the lucky coin that triggers it.

It’s possible to spin up more than one Pot of Gold Free Spins bonus at once. Activate all three together and you’ll benefit from expanded reels, nudging Wilds, multipliers, instant wins, extra free spins and the chance to scoop a Jackpot prize too!

Multiple Bonuses

Each bonus comes with its own unique features, and you can activate more than one at a time with the lucky coins. Trigger all three at once for a full house of bonus features and some incredible opportunities!

Nudging Wilds

Stacked Wilds nudge and expand during the Green Pots of Gold Free Spins bonus feature. They’ll fill entire reels, if that improves your winning opportunities - leading to the possibility of even bigger prizes.

3 Lucky Rainbows Review

The luck of the Irish is legendary, which is presumably why it’s such a popular theme with slot players. The expectation is for an engaging slot with a jaunty feel and some interesting game mechanics, and SpinPlay certainly seems to have delivered on that score!

The game seems fresh and inviting from the moment it launches, with familiar symbols, such as a golden harp, a foaming pint of beer and a leprechaun’s hat.

But as enchanting as the overall scene may appear, the game packs a fair degree of volatility. It’s not quite into the high variance territory, but it’s certainly not far off, so a degree of caution is required when approaching gameplay for the first time.

But with three free spins bonus features, four fixed Jackpot prizes and a potential top payout worth 5,000x your stake, there are plenty of reasons to give it a try.


You’ll discover all the familiar Irish-themed symbols on the reels of 3 Lucky Rainbows, but the developer has given them some unique touches. Even the leprechaun’s hat, which is the game’s Wild symbol, has been sprinkled with gold, and streaks of light flash across winning lines making them easier to spot. 

Green and gold are the predominant colours in this game, with a gentle background scene of hillocks and wildflowers. There’s an Irish folk music-inspired soundtrack, but don’t let that put you off! SpinPlay has included a woodwind element, which helps to make it simultaneously soothing, yet toe-tapping. It makes for an atmospheric and immersive gameplay experience, which is a good reason to set out a budget before you start spinning the reels!


Although 3 Lucky Rainbows looks much like any other 5 x 3 slot, this is a game that’s worth playing in demo mode before you start wagering real money. That’s not because the gaming mechanics are particularly complex – free spins, multipliers, nudging Wilds and fixed Jackpots are all well-known in the slots gaming world. But it’s the way these elements have been spread across three separate free spin bonus features that makes this game so different.

That above-average volatility also has an effect, so although it’s possible to spin up multiple bonus rounds at once, it’s equally likely that you might play through a prolonged dry spell, with no bonus games, so no big wins. For that reason alone, it’s worth taking the time to explore the gameplay for yourself before taking any financial risks.

Win Potential

You’ll need to spin up at least five-of-a-kind playing card icons across a payline to see your stake returned, but better rewards come from the game’s themed symbols. The gold and emerald four-leaf clover return up to 5x your stake, which increases to 10x for matching five Wilds across a payline.

The game offers four Jackpot prizes, displayed alongside the reels. The amounts shown are based on your current wager, with the payouts calculated as follows:

The RTP of 96.47% suggests that there are some good payouts on offer, and with betting options ranging from just 0.20 up to 50.00 per game, most slots fans will be able to find their personal sweet spot. That top payout of up to 5,000x your total bet is certainly eye-catching, so there’ll be no shortage of players lining up to play 3 Lucky Rainbows.

Our Verdict

SpinPlay slots are proving to be a big hit with slots fans, thanks to careful attention to game design and some interesting mechanics. And there’s no reason why 3 Lucky Rainbows shouldn’t go on to be a big hit with players, thanks to the variety of free spins bonus rounds and accompanying modifiers.

Although the game seems to offer standard gameplay during the base game, it’s during the free spins bonus rounds that things become more complex. Guaranteed multipliers, nudging Wilds, instant credit wins and big Jackpot prizes ramp up the excitement levels – as well as the winning potential. Just make sure you take the time to fully understand the free spins bonus features before putting your bankroll on the line.
