Rainbow Jackpots Slot Review, Red Tiger’s Modern Take on the Irish Lucky Slot

Looking for slots like Rainbow Jackpots? Start with Rainbow Jackpots Power Lines for the closest sequel, Rainbow Jackpots Megaways for a variable-reel version with a higher ceiling, or Rainbow Riches for another established Irish slot with several bonus rounds.
Red Tiger’s original Rainbow Jackpots uses five reels, three rows and 20 fixed paylines with a 96.14% RTP. The Lucky Leprechaun can appear on any spin to trigger Symbol Swap, Mega Symbol Swap, the Beer Bonus or enhanced bonus symbols. Three pots award free spins, while a Mega Free Spins symbol can award 30 to 100 spins.
Red Tiger Gaming released Rainbow Jackpots into a market already saturated with Irish-themed slots, but carved out its own space by making the Leprechaun genuinely unpredictable. Rather than a slot where the leprechaun is decorative, Red Tiger made him the game’s central mechanic, he appears randomly on any spin, modifying the reels with wilds or mega symbols, handing out the Beer Bonus, or potentially awarding up to 100 Mega Free Spins if the stars align. The tension of wondering what he will do, or whether he will merely tease before vanishing, gives Rainbow Jackpots a personality that most Irish-themed slots lack. It is a formula Red Tiger has repeated across its wider catalogue of slots, and players who enjoy the Leprechaun’s unpredictability should also try Dynamite Riches, another Red Tiger title built around a similarly random, high-impact bonus feature.
The 96.14% RTP is above the UK online average at the default setting, though Red Tiger operates variable configurations, some operators run this game lower. The 1,054x base max win is modest, but the Leprechaun’s appearance is itself the entertainment, and free spins up to 100 represent an unusually generous upper boundary for the genre.

Game Information
Rainbow Jackpots: Pros and Cons
Pros
- The Lucky Leprechaun’s random appearances make the base game genuinely unpredictable, he can appear on any spin without warning and trigger anything from a small wild placement to a 100-spin Mega Free Spins award
- 96.14% RTP at the default configuration is above the UK online average, solid value for a medium-to-high volatility slot with multiple bonus mechanics
- The Beer Bonus offers immediate cash prizes without needing to sit through a full free spins sequence, a fast-resolving pick-me feature within the wider mechanic structure
- Up to 100 Mega Free Spins represents an exceptional upper boundary, most Irish-themed slots cap at 20 or 25 free spins; 100 spins with all random Leprechaun features active at maximum frequency is the kind of session-defining event players talk about
- The franchise has grown significantly, Rainbow Jackpots Megaways with a 20,000x ceiling and multiple feature buys offers players who want more depth a direct upgrade within the same universe
Cons
- The 1,054x base max win is the lowest ceiling of any slot in the top 20 on this site, if the Leprechaun never grants Mega Free Spins, the game’s actual win potential is quite limited
- The Leprechaun can tease, he occasionally appears on the reels, does his little animation, and then disappears without triggering any feature. Players have described this as the game’s most frustrating characteristic
- Medium-to-high volatility with fully stacked symbols means losing streaks during the base game can be extended, the hit frequency of around 16.4% means most spins produce no win at all
- Variable RTP configurations are available, some operators run Rainbow Jackpots below the default 96.14%; always verify which version is active at your chosen casino
How Rainbow Jackpots Works
The game uses a five-reel, three-row grid with 20 fixed paylines paying left to right from reel one. All symbols can appear stacked, covering an entire reel in a single landing, when stacked symbols align across multiple reels the combination produces large payline wins. Minimum bet is £0.20, maximum is £100. Three scatter symbols on reels 1, 3 and 5 simultaneously trigger the Free Spins feature.
The Lucky Leprechaun is not a symbol in the traditional sense, he is an animated character who appears on the reels from time to time and physically interacts with the game. His appearances are random and his actions vary: he might place wild symbols on specific reels, convert symbols into mega symbols, activate the Beer Bonus, or announce Free Spins. His arrival is always heralded, but what he will do when he gets there is never guaranteed in advance.
The Beer Bonus
When the Leprechaun triggers the Beer Bonus, a selection of beer bottles appears on screen. Players choose one to reveal a cash prize expressed as a multiplier of the total bet. The pick resolves immediately, it is a single-choice feature with no progressive stages.
Free Spins and Mega Free Spins
Scatter triggers on reels 1, 3 and 5 open a pot selection, three pots reveal between 6 and 20 free spins. However, if the Lucky Leprechaun decides to intervene at the trigger moment, he may upgrade the standard free spins to Mega Free Spins, awarding up to 100 spins. During both standard free spins and Mega Free Spins, the Leprechaun’s random features trigger with higher frequency than in the base game, meaning more regular wild placements, mega symbols and bonus interactions throughout the bonus window.
Our Verdict
Rainbow Jackpots succeeds by making its central character do actual work rather than just decorating the reels. The Lucky Leprechaun’s random interventions give the base game a watchfulness that most Irish slots cannot replicate, you genuinely never know what each spin will produce beyond the standard payline outcomes. The Beer Bonus adds a quick-resolve reward loop, and Mega Free Spins at 100 spins with enhanced feature frequency is as good as the genre gets.
The 1,054x ceiling is the honest limitation, this is entertainment rather than a life-changing payout slot. For that specific proposition, Rainbow Jackpots does it very well.
SlotsLike rating: 7/10, The Irish slot where the Leprechaun genuinely matters. Unpredictable random features, 96.14% RTP, Beer Bonus and potentially 100 Mega Free Spins make it one of the more engaging titles in a crowded genre.

Games like Rainbow Jackpots
Rainbow Jackpots Power Lines
Rainbow Jackpots Power Lines is the closest sequel, keeping Lucky the Leprechaun and the same Irish setting while changing the win system. Choose it when the character and random features matter more than matching the original 20-line grid.
Rainbow Jackpots Megaways
Rainbow Jackpots Megaways takes the franchise into a variable-reel format with more possible ways to win and a larger top prize. It is the more volatile alternative for players who find the original’s 1,054x ceiling restrictive.
Rainbow Riches
Rainbow Riches is not part of Red Tiger’s series, but it is the clearest alternative for a familiar Irish theme and several distinct bonus rounds. Its Road to Riches, Pots of Gold and Wishing Well features replace Rainbow Jackpots’ random Leprechaun events.

Rainbow Jackpots, Frequently Asked Questions
What does the Lucky Leprechaun do in Rainbow Jackpots?
The Lucky Leprechaun appears randomly on any base game or free spins spin without warning. When he arrives, he can do one of several things: place wild symbols on specific reels, transform symbols into mega symbols, trigger the Beer Bonus pick-me feature, upgrade free spins to Mega Free Spins (up to 100 spins), or occasionally tease by appearing and then leaving without triggering anything. His behaviour is unpredictable, each appearance could be a small enhancement or the event that defines the entire session.
How do you get 100 free spins in Rainbow Jackpots?
The standard scatter trigger (three pots on reels 1, 3 and 5) opens a pot selection revealing 6 to 20 free spins. If the Lucky Leprechaun decides to intervene at the trigger moment, he can upgrade the standard award to Mega Free Spins, up to 100 spins with enhanced random feature frequency throughout the bonus. This upgrade is random and cannot be forced. It is one of the rarer events in the game, but when it triggers alongside a favourable session it delivers the most memorable outcomes.
What is the RTP of Rainbow Jackpots?
The default RTP is 96.14%, above the UK online average. Red Tiger Gaming offers multiple RTP configurations to operators, the game can be set lower than the default at some casinos. Always check the information panel within the game at your chosen casino before playing to confirm which version is active.
Is Rainbow Jackpots related to Rainbow Riches?
No. Rainbow Jackpots is a Red Tiger Gaming original and has no mechanical or commercial connection to Rainbow Riches, which is a Barcrest (Light & Wonder) product. They share an Irish leprechaun theme, as do dozens of other slots, but the mechanics, developer and paytable are completely different. Rainbow Jackpots does not licence or extend the Rainbow Riches brand in any way.
What is the difference between Rainbow Jackpots and Rainbow Jackpots Megaways?
Rainbow Jackpots Megaways applies the Megaways engine to the same leprechaun universe, six reels, up to 117,649 ways to win, cascading reels and an unlimited win multiplier during free spins. The Megaways version has a higher max win of 20,000x stake but a slightly lower default RTP of 95.77%; Red Tiger’s own site lists a £50 max bet for it (some UK operators cap it lower because of its feature-buy option). The original sits at 96.14% RTP, £100 max bet, and a modest 1,054x ceiling. Choose the original for value and stake flexibility; choose Megaways for win potential ceiling.
