Rainbow Wilds Slot Game Background

UK-based Iron Dog Studio was founded only in 2017, however in that short time the studio has garnered a reputation for developing stellar Megaways slots, including 1 Million Megaways BC and 1 Million Fortunes Megaways, both offering a staggering potential one million paylines. Rainbow Wilds itself received its own Megaways sequel in 2021.

Rainbow Wilds Slot Game Design

Rainbow Wilds is a 5-reel, 4-row online casino game with an above average 1,024 paylines and a potential maximum payout of 300,000x the stake thanks to the slot's cascading reels feature.

Being a slot revolving around a mystical Celtic theme, the game takes place in an idyllic woodland forest where a band of cheeky leprechauns live among the emerald green plants and flowers. A placid-looking lake is glimpsed in the background and is ranged by two sloping hills. Above is a pleasant cloud-filled sky. The game grid (encased in an ornate gold frame with several Celtic flourishes) dominates the screen. The reels are completely see-through and feature fruit clumps alongside more traditionally Irish and bonus symbols. The accompanying music (dominated by piano, flutes and violin stirrings) is lilting and ethereal, particularly between spins, conjuring a fantastic magical vibe that's wonderfully atmospheric. Rainbow Wilds also features various sound effects and jingles when spinning the reels or landing a winning combination. Occasionally, one of the leprechauns will step out from behind the bushes and giggle.

Rainbow Wilds Slot Mobile

Rainbow Wilds, like all the online slot games available on the Lottomart site, can be played on desktop PCs and laptops alongside mobile devices such as Android and Apple. All that's needed is a stable Internet connection or mobile data..

Rainbow Wilds Slot Symbols

The fruit berry clumps represent the lowest value symbols in this Rainbow Wilds slot, ranging in value between 10x - 30x the stake for 5-of-a-kind on the reels, followed by the Beer (50x the stake), Harp (80x the stake), Heart (120x the stake), gilded Bird (150x the stake) and gold Horseshoe (250x the stake). However, the highest paying symbol in the game is the golden Four-Leaf Clover and its payout of 400x the stake for 5-of-a-kind on the reels.

This Rainbow Wilds slot also has its share of bonus symbols. The first is the rainbow-coloured Wild Star symbol that appears on 2, 3, 4, and 5 and substitutes for all other base game symbols like with most online casino games. Second, the gold pot Sticky Wild symbol is found only on reel 3 and doesn't disappear after participating in a winning combination. Instead, it cascades down the reels if the symbols below it disappear during a tumble. Otherwise, it performs the same function as the Wild Star symbol. Third, the rainbow star Expanding Wild can appear on reels 2, 3, 4, and 5, substituting for all other symbols when it does. Also (and as the name implies), Expanding Wilds can expand to cover multiple positions or even an entire reel.

Rainbow Wilds Slot Bonus Features

This Rainbow Wilds slot offers a couple of Celtic-themed bonuses that include Megaways-style cascading reels with a Free Spins bonus round with bet multipliers!

Tumble Feature

Cascading reels is a feature normally found in Megaways slots, so it's great to see that Iron Dog Studio has seen fit to include it in this slot (that doesn't use Big Time Gaming's proprietary game engine). And if you have spent any time playing Megaways slots, you'll be familiar with this feature. Symbols in winning combinations get destroyed and disappear from the reels, creating space for other symbols (including an increased chance of extra Wild Star symbols) to fall into the recently vacated positions. These new symbols are the same size as the ones they replaced. Tumbles continue until no more winning combinations appear as a result.

Free Spins Feature

This feature is triggered by landing at least four consecutive tumbles, and each successful tumble over and above the four needed awards further spins and even bet multipliers:

  • 4 successful tumbles = 14 Free Spins.
  • 5 successful tumbles = 16 Free Spins.
  • 6 successful tumbles = 16 Free Spins. + starting multiplier of 3x the stake.
  • 7 successful tumbles = 20 Free Spins. + starting multiplier of 3x the stake.
  • 8 successful tumbles = 20 Free Spins. + starting multiplier of 6x the stake.

Rainbow Wilds Slot Summary

The Rainbow Wilds slot is a brilliant addition to Iron Dog Studio's slot catalogue thanks to the title's mystical Celtic woodland theme that showcases a superb audio-visual presentation alongside an exciting array of bonus rounds featuring three Wild symbols, cascading reels, and more.
