As today is Find a Rainbow Day, I thought it would a good opportunity to find the very best Rainbow titled slots and gather them together for you in one easy to access list of 10.
Whilst there are lots, and I mean lots, of slots that have a rainbow in them somewhere, for the purpose of this list I will be focusing purely on slots that have the word in the title. This narrows things down quite significantly, but is unlikely to see us steering very far from the Irish leprechaun path.
Newton and Rainbows
Since Sir Isaac Newton published his paper on light refraction in 1672 we have had the theory to understand that rainbows are illusions, a trick of the eye formed by the refraction and reflection of light inside droplets of water with our eyes acting as the reflective conduit: White light splayed out into red, orange, yellow, green, blue, indigo and violet. Its place in the sky is dependent on our place on the ground and as such it will always appear in the distance; its end, its pot of gold, always just over there.
Despite there being no end and no treasure waiting there for us, it does not take away from the brilliance of the light show. We can have the magic explained but it doesn’t stop us craning out the window to for a better look.
Before the science was properly understood different cultures attached their own meaning and significance to rainbows.
Culture and Rainbows
The Greeks and the Romans believed that rainbows were a path made by a messenger that travelled between Earth and Heaven. The Chinese believes that a rainbow was a slit in the sky sealed by the goddess Nüwa using stones of five different colours. In the Bible God placed a rainbow in the sky as a promise to humanity that he would never destroy the earth again following the great flood. In Hindu philosophy, the seven colours of the rainbow represent the seven chakras, from the first chakra (red) to the seventh chakra (violet). And arguably, the most well-known cultural belief comes from the Irish who as we all know believed there was a pot of gold guarded by a leprechaun sitting at the other end of the rainbow.
Cinema, music, literature and art are all filled with references to rainbows. The best example, one that crosses two of those mediums is “Over the Rainbow”, the song that was first heard in “The Wizard of Oz”, sung by Dorothy as she fantasied about a place where everyone lives in peace and harmony, a place that exists somewhere, over the rainbow. Since then it has been sung countless numbers of times with, its last major outing being the Eva Cassidy version that climbed the UK charts back in 2001, 5 years after the singer lost her battle with cancer.
There is even a computer game series that is based off a Tom Clancy novel that both have the word Rainbow in the title, the significance of which is something that I am not entirely sure of, but is just further evidence of the enduring reach and symbolism of the spectrum.
Rainbows and Hope
For many, rainbows are a symbol of peace and tranquility; of good luck and good omens. For some they are not just the calm after the storm but a symbol of beauty that is born out of turbulence.
In the trying fear and uncertainty of a Covid-19 maelstrom rainbows are once again being reached for and used as a sign of hope when we need it the most. Children in the UK have been drawing, painting and crafting their own rainbows and placing them in windows as a sign of hope following nationwide school closures. This is arguably the most universally frightening time for the entirety of species humanity since war ravaged the globe’s four corners and as we struggle to cope with the changes and as we fear for our most vulnerable we can glance up into the sky together and hope that this becomes one end that we can reach.
Nineteenth-century English poet John Keats lamented Newton’s work, claiming it had stolen something magical from us. He believed that Newton had “Destroyed the poetry of the rainbow by reducing it to a prism.” And went on say that physics “Will clip an Angel’s wings/Conquer all mysteries by rule and line/Empty the haunted air, and gnomed mine/Unweave a rainbow.” He said this 200 years ago, well over 100 years after Newton published his papers and yet centuries later children can understand the cold unemotional science of rainbows and still find magic within the prism.
South Africa was coined the Rainbow Nation by Nelson Mandela because he wanted to celebrate the colour, vitality and the heritage of a country that had been stripped of everything after half a century of brutal apartheid. He created hope when hope had all but gone and used the rainbow as his metaphor to tell battered and bedraggled people that they were beautiful and that they could look forward to brighter, more colourful future if they could believe in one.
Rainbows are symbol for the LGBTQ movement. A symbol for diversity. We are all one of the same, but ultimately different. Like the white light we should celebrate the whole spectrum but also appreciate that all of us land on our place, our colour and that the diversity in gender, in race, in everything that makes being an individual within a much greater mass should be celebrated.
If the shadow of a global pandemic teaches us anything it is that we are all the same and yet all completely different. All of us are susceptible to the virus, regardless of race, gender or class. We might not have the same means to combat it but we are all in this together, all the same and yet all completely different.
What Keats couldn’t have known when he accused Newton of clipping the wings of his imagination was that by understanding more about the physics of light we now have a narrower field in which to flex those imaginations. The perimeter of the field may be narrower than it was before but its soil is better tended, richer in nutrients and yields more fruit than the previous scatter gun approach ever did.
It’s very likely that my summary of each of these slots will have a reasonable amount of information repeated. As such I’ll keep things as short and precise as possible. I also want to provide a disclaimer that, given the narrow parameters I have set myself here that not all the slots on this are what you might describe as a classic, but hopefully there will be something in here that all slots fans can find to enjoy.
Do I need to say anything about the Rainbow Riches slot? A certified classic slot, one that just about everyone has played and one that you will see riding high in most played slots lists everywhere.
The second of our rainbow franchises is taken from Red Tiger and whilst slightly less well known the Rainbow Jackpots slot actually scored better from us on initial review. You get Free Spins, Mega Free Spins, Wilds and multipliers, which means there is no shortage of features on offer. At less than 4% the house edge is offering decent value for money too.
The Rainbrew slot is twisting the rules a little, but is as close to having rainbow in title as you get without it actually being there. It is a stunning looking slot with a host of different features and relatively competitive house edge.
Rainbow Riches: Reels of Gold
The Rainbow Riches: Reels of Gold slot might be from the same developers as the original Rainbow Riches slot but this one is heads and shoulders one of the best in the franchise. Scoring an impressive 10 out of 10 from us on initial review, we couldn’t find anything to criticise.
The Rainbow Ryan slot is the only Yggdrasil release on this list. Like most of their slots, this one looks fantastic, and is most probably the best looking slot here. You get the usual mix of basic features plus synchronised reels.
Fruit Rainbow is the newest slot here. It is probably the most basic slot but is easily one of the brightest and most vibrant. The undeniable star of this has to be the low house edge, making this a slot that is offering excellent value for money.
Rainbow Riches: Megaways
If you are going to have a slot franchise and are stuck with where to go next then surely the most logical conclusion is a Megaways slot. With the Rainbow Riches: Megaways slot you get the maximum number of Megaways, Free Spins, Multipliers, Buy Now features and much more.
Rainbow Jackpot: Powerlines
Whilst the title of Rainbow Jackpots: Powerlines might sound more impressive than the original there really isn’t all that much to choose between the two. It’s a bit bigger than the original, but it looks the same. There are pros and cons between the two that you you’d need to make your own mind up on.
The Rainbow Wilds slot, designed by Iron Dog is a fairly basic looking slot but one that makes very most of what it has to offer. If you like Wilds then this slot is the Rainbow slot of choice for you, with multiple different Wild symbols in action.
Rainbow Riches: Pick ‘n’ Mix
The Rainbow Riches: Pick ‘n’ Mix slot is the last on this list, and what a way to end. Again, this one earned the full 10 out of 10 from us. Even though it is clearly targeted at those with a fair amount of disposable income, as higher bets reward the best house edge, we still felt there was enough here to warrant the perfect score.
