Rainbow Wilds Megaways is a new video slot from Iron Dog Studios, and it’s a sequel to Rainbow Wilds which they released in 2018. Rainbow Wilds Megaways has 6 reels and up to 117,649-ways-to-win on every spin. Players can spin the reels from between 0.10 and 50 credits per spin, and the slot’s RTP is 95.8%. The game’s bonuses and features include cascading reels, wilds, free spins and a progressive multiplier.


2018 saw Iron Dog Studios releasing a game called Rainbow Wilds - an Irish-inspired slot that never really took off. It’s back, however, with a bit of a twist - and Rainbow Wilds Megaways is a sequel to the original game, the main difference being, of course, the inclusion of Big Time Gaming’s Megaways mechanic!

In this Rainbow Wilds Megaways slot review we’re going to be taking a look at Rainbow Wilds Megaways and what it has to offer; and we’ll give you a breakdown of what to expect when playing the slot for yourself. Let’s start off with a look at the game’s format and betting options.

Format and Betting Options

Rainbow Wilds Megaways uses Big Time Gaming’s Megaways mechanic, and this means there are 6 reels, and between 2-7 symbols on each row. If 7 symbols land on each reel, the maximum 117,649-ways-to-win will be active - and here, both in the base-game and the free spins bonus round - you can form some pretty decent sized hits if the symbols line up correctly!

When it comes to betting options, Rainbow Wilds Megaways offers a relatively high max bet for a Megaways slot; you can wager as much as 50 credits per spin! The minimum bet is also really low - so players on both ends of the scale are able to enjoy the slot. The minimum bet is just 0.10 credits!

Graphics and Theme

While it’s clear Rainbow Wilds Megaways is an Irish/Leprechaun-inspired slot, Iron Dog Studios haven’t plastered gold coins, pots of gold and Leprechauns all over the place - and the backdrop actually looks more like an enchanted forest, in our opinion.

It looks pretty good - albeit basic, something we’ve noticed is a trend in the game developer’s slots - and a fitting audio soundtrack accompanies each spin. It’s a good balance we feel, as the theme isn’t too intense; you know it’s there, but when you’re immersed in the slot, you don’t really notice it’s yet another Irish-themed game!

Rainbow Wilds Megaways’ RTP and Volatility

As you’d probably expect from a Megaways slot, Rainbow Wilds Megaways is classified as being high variance - and this means that you’ll see wins forming less frequently than you would if you were playing a low or medium variance video slot. However, the flip side to this is that when wins do land, they tend to be worth much more - and the game offers players the chance to win as much as 12,000X their stake, so there’s some fantastic win-potential on offer!

When it comes to RTP, Rainbow Wilds Megaways comes in at 95.8%. It’s a tad below the 96% figure we like to see with online video slots - but it’s not bad and is only a smudge under - so it shouldn’t have any noticeable effect on your gameplay in the short-term - or even the long term, unless you’re putting billions of spins through the game!

Bonus Features

Like most Megaways slots, Rainbow Wilds Megaways has plenty going on - and in this part of our review we’re going to be taking a look at the bonuses and features you’ll find within the slot.

Cascading Reels

Cascading - or Tumbling - Reels is a mechanic we see in the vast majority of Megaways slots, and it’s become, clearly, a popular choice with both players and game developers. Whenever a win is formed, the symbols that were involved with that win drop away off the screen, and new symbols then drop down to take their place. This means the ‘cascading’ mechanic can continue for quite some time, and, as you’ll soon see, these cascades are also the key to triggering the main bonus round!

Wild Modifiers

When you play Rainbow Wilds Megaways you’ll notice there are three different types of wilds; the regular wilds, the Mushroom wilds and the Sticky wilds. The regular wilds appear during both the base-game and the free spins bonus, and they all carry a win multiplier of 1X. They substitute for all the game’s symbols, making it easier to form wins when they land in view.

The Mushroom wild can also appear during both the base-game and the bonus round - although only one can land at a time, on reels three or four. When this wild lands, it then creates up to three additional wild symbols on reels 2-5, and any regular wilds in view have their multipliers increased by 1X if they’re on the same screen - so this can actually be quite a lucrative base-game feature.

Finally, there’s the Sticky wilds - and these are found only during the free spins bonus. Sticky wild multipliers begin with a 1X multiplier, and this multiplier increases by +1 on each winning cascade. They are not permanently sticky, however, only remaining stuck in place for the duration of one spin.

Free Spins

The highlight of Rainbow Wilds Megaways is undoubtedly the free spins bonus round, and this is triggered by getting four consecutive cascades during the base-game. 4 cascades awards you with 8 free spins, while each additional cascade after this awards 2 extra free spins.

During the free spins bonus round, a progressive multiplier comes into play, starting at 1X and increasing by +1 upon each cascade. This win multiplier then holds - and continues to grow - for the duration of the free spins bonus, applying itself against any wins formed. As mentioned earlier, there’s also sticky wilds present during the free spins bonus - though they’re not fully sticky as they only lock in place for the duration of one cascade sequence.

Bonus Buy

Like we’ve seen in a number of the game developer’s other video slots, Rainbow Wilds Megaways also offers a Bonus Buy option - available to all players located outside of the UK. This lets you purchase the free spins bonus, and it costs 85X your stake for 8 free spins and 115X your stake for 10 free spins.

Rainbow Wilds Megaways Review

While Rainbow Wilds Megaways does mean yet another Irish/Leprechaun-inspired slot hitting the online gambling marketplace, Iron Dog Studios have, we feel, done enough to make sure this slot doesn’t just fall “in line” with the hundreds of other Irish-themed games out there - and while the game is clearly Irish - the imagery and backdrop show that pretty much from the get go - there’s plenty going on within the slot to take your mind away from the game and focus more on the gameplay - and, on the whole, we don’t feel it’s a bad effort from the software provider.

In some of the game developer’s previous Megaways slots we’ve seen them really pushing the limits - even going so far as to build slots with up to one million ways to win, as we saw in - fittingly - 1 Million Megaways BC. With Rainbow Wilds Megaways they chose not to push the boundaries so hard - but that doesn’t mean it’s a bad game, and well-placed sticky wilds alongside a free spins bonus round with a progressive multiplier ensures the game offers decent entertainment value for players.

We also like the fact that Rainbow Wilds Megaways offers players the chance to win up to 12,000X their stake - an amount that’s enough to tempt even the most highest win-seeking of gambler - and some decent stats, decent bonuses and features and relatively well made graphics and audio animations make Rainbow Wilds Megaways a very playable slot, in our opinion.

Rainbow Wilds Megaways FAQs

How much can I win?

In the past few months we’ve seen more and more video slots coming out with major win-potential - and, when we say major, we’re talking 20,000X+ win-potential. Rainbow Wilds Megaways doesn’t offer quite that much win-potential - and the most you can win from a single spin is 12,000 times your stake - but that’s still a fairly healthy amount of money.

Is Rainbow Wilds Megaways a Big Time Gaming slot?

No. While Rainbow Wilds Megaways uses Big Time Gaming’s Megaways mechanic, it’s not a game that they’ve actually produced. It was made by a smaller software provider called Iron Dog Studios, who purchased a license from the Australian game developer to use the Megaways license in their slots.

What is the RTP of Rainbow Wilds Megaways?

While the vast majority of Megaways slots tend to have decent RTPs, Rainbow Wilds Megaways is one of the few that drops into the 95% region - and while this isn’t a huge issue, we would prefer to see the game with an RTP above 96%. Still, the RTP of 95.8% is only a tad below - and this shouldn’t really affect you playing experience in the short-term, so you shouldn't worry too much about it.

What game is Rainbow Wilds Megaways based on?

Back in their earlier days, Iron Dog Studios released a game called Rainbow Wilds, and while it never achieved any real success in the online gambling world, it did set the scene for their latest Megaways release - Rainbow Wilds Megaways. The sequel has much more to offer than the original, so while the theme is consistent - pretty much all other areas of the game are different, and it is, essentially, a completely different machine!
