Emerald King: Rainbow Road Slot RTP, Details & Wager Limits

The Emerald King: Rainbow Road slot has 5 reels, 3 rows and just 20 paylines. Landing 3, 4 or 5 matching symbols or wilds on a payline, starting from reel 1 creates a winner.

You can start your journey down the Rainbow Road at stake levels that range from between 20p and £240 per spin. Autoplay is available too. You can run up to 1,000 autospins if required.

The Emerald King: Rainbow Road RTP is 96.71% which stacks up pretty well above the average. The gameplay is simple but volatile. The variance here is high. One a scale of 1 to 10, the volatility is a fiery 10. The max payout is 20,000 x your total stake.

Theme – Audio & Design Features – find treasure at the end of the rainbow


With an Irish luck theme, the design in the Emerald King: Rainbow Road slot is rather basic. The game is part of the Reel Kingdom series which means it’s simple. This is a proper no-frills slot when it comes to design.

On the green reels you’ll find A to 10 royals plus a logo symbol. This logo is the most lucrative symbol. Land 3, 4 or 5 on a payline for an award of 5, 15 or 25 x your total stake.

The coin with the 4-leaf clover emblem is the wild. This can land on all 5 reels and replace all the standard symbols when it forms part of a winning combination. There are also 2 scatters: the leprechaun and the pot of gold. These can both land on reels 3, 4 and 5. Land 3 of them on the same spin to trigger a feature.

Pragmatic Play has created full optimised versions of this slot for smartphones and tablets as well as computers. The design is simple but the bright colours stand out nicely on small screens. The gameplay is also pretty straightforward and you’ll have no problems playing the Emerald King: Rainbow Road mobile slot.

Emerald King: Rainbow Road Bonus Features

Pragmatic Play has taken features commonly found in Irish fortune themed slots and given them a shake in Emerald King: Rainbow Road. You’ll find pick me prizes and cash trails here but the way they do things is a bit different from the norm.

Rainbow Road feature


The Rainbow Road feature triggers when you land the leprechaun scatter symbol on reels 3, 4 and 5 on the same spin or via the Scatter Eliminator Bonus feature(which I’ll look at shortly).

There are 22 points on the Rainbow Road, each one potentially awarding a cash prize or a spin of the Mini Slots Bonus which can award up to 6 points or a collect. If you hit the collect, the prize from the current point on the trail is awarded.

If you make it all the way to the last point on the map you’ll get to play for Big Money. This awards a random cash prize of between 50 and 20,000 x your total stake. Its similar to the Road to Riches Bonus features in Rainbow Riches.

Scatter Eliminator Bonus feature

Land 3 pot of gold scatter symbols on reels 3, 4 and 5 to activate the Scatter Eliminator Bonus feature. This is a variation on the pick me round. Pick from the pots of gold to eliminate them.

The prize behind the last scatter standing is what you’ll win. Prizes here vary depending on how many scatters triggered the feature:

  • 3 scatters = a prize of between 5 and 20 x total stake
  • 4 scatters = a prize of between 10 and 40 x total stake
  • 5 scatters = a prize of between 50 and 200 x total stake

You could also trigger the Rainbow Road feature regardless of whether you triggered the Scatter Eliminator with 3, 4 or 5 scatters.

Emerald King Mini Slots Bonus feature


On any base game spin, you could see the reels turn green. When all 5 reels go green on the same spin you’ll bring the Emerald King Mini Slots Bonus feature into play.

You’ll then be awarded spins on between 1 and 15 new sets of mini reels which each have 1 payline. How many sets of reels are awarded is chosen at random. These Mini Reels are each made up blue, yellow and red 7 symbols as well as blanks. Here’s what they pay:

3 x of any coloured 7 1 x stake
3 x blue 7s 5 x stake
3 x yellow 7s 10 x stake
3 x red 7s 15 x stake

Each set of reels keeps on spinning until there’s a spin that contains a blank and therefore no winning combination. That reel is then removed from the screen. The feature ends when all the Mini Slots are removed from play. This is very similar to the Reel King feature from the Reel King slot.

Emerald King: Rainbow Road Review Summary – great slots ‘mash-up’

The Emerald King: Rainbow Road slot has all the elements from other popular slots like Rainbow Riches and Reel King. However, it’s all about the Rainbow Road feature where prizes of up to 20,000 x your total stake can be won.

You will also find the classic Reel King feature from Reel King which is a nice touch for fans of Novomatic’s iconic game. Pragmatic Play has given the features a twist to offer something a little different.

Don’t expect much in the way of flair as far as design is concerned here. This is a very simple looking slot. Saying that, it’s high variance and has the potential for huge wins from the Rainbow Road feature. The max win per spin is 500 x stake so you need to trigger the feature for the bigger payouts.

Emerald Gold: Rainbow Road is a decent game which is catered to players who have played other classic slot games. If you want more Irish luck, Rainbow Riches Megaways would be my pick.
