RECOMMENDED CASINOS TO PLAY Luck O the Irish Rainbow Spins
Luck O the Irish Rainbow Spins £500 Jackpot Gameplay & Features
Wins are awarded in the traditional fashion—3 or more matching symbols aligned along any of the 10 paylines from left to right. But this isn’t just your standard Irish-themed slot. Rainbow Spins introduces a stacked Mystery Symbol, a Free Spins bonus, and a Pie Gamble system that adds player choice and strategy.
It’s a refreshing blend of traditional gameplay with modern enhancements—comparable to games like 100,000 Pyramid, Book of Ra Deluxe, or Irish Pot Luck.
Mystery Symbol: Hidden Wins Await
The Mystery Symbol plays a central role in Luck O’ the Irish: Rainbow Spins, especially in bonus modes.
Where It Appears:
-
During Rainbow Spins
-
In Power Play mode (exclusive to £2 stake)
-
Stacked on the reels when active
When revealed, the Mystery Symbol transforms into any base game symbol, potentially filling the screen with matching icons for larger win combinations. This mechanic works similarly to the Mystery Symbols in Bonanza or Buffalo Rising Megaways, though here it’s more tightly controlled and visual.
Rainbow Spins: Free Spins with Mystery Potential
The Rainbow Spins feature functions as the game’s main Free Spins round.
How to Trigger:
-
Via the Pie Gamble (after a base game win)
-
Or during Power Play, when Mystery Symbols reveal spins (on £2 stake only)
What Makes It Special:
-
Mystery Symbols are guaranteed to appear during Rainbow Spins.
-
Each Mystery Symbol can reveal any base game symbol, creating potential for stacked high-value wins.
The feature isn’t overly complex but delivers solid excitement thanks to the surprise element of the reveals. It’s ideal for players who enjoy symbol-reveal mechanics, much like Book of Oz: Lock ‘N Spin or Rise of Merlin.
Power Play: Bigger Bets, Bigger Bonuses
Exclusive to the £2 stake level, Power Play enhances gameplay by boosting the impact of the Mystery Symbols.
Key Features in Power Play:
-
Mystery Symbols may reveal Rainbow Spins directly.
-
Each Rainbow Spin revealed is added up, giving you a total number of spins awarded.
-
Mystery Symbols may still reveal regular reel symbols, keeping the outcome unpredictable.
This mechanic adds a layer of collect-and-reveal excitement and is similar in spirit to bonus-boosting systems found in games like Big Bass Bonanza Megaways or Irish Frenzy when played at higher stakes.
Pie Gamble: Take a Risk for Spins or Cash
After any qualifying reel win, players can choose to enter the Pie Gamble feature.
Your Options:
-
Gamble for cash – step up winnings, up to a maximum of £500
-
Gamble for Rainbow Spins – go for up to 25 Free Spins
How It Works:
-
A pie-style dial appears with green (win) and red (lose) segments.
-
The size of the green area changes depending on the potential prize.
-
Choose your goal—cash or spins—and spin the dial.
-
Land in green to claim your prize; red means the gamble is lost.
This gives players a true risk-reward decision, and echoes features found in Blueprint’s Mega Bars series or reel ladder gamble systems in pub-style fruit machines.
Conclusion:
Luck O’ the Irish: Rainbow Spins blends the simplicity of a 10-line slot with just enough bonus mechanics to offer real depth. Whether it’s the stacked Mystery Symbols, the strategic Pie Gamble, or the suspense-filled Rainbow Spins, this game keeps players involved without overcomplicating things.
With:
-
A familiar yet fresh Irish theme,
-
Expanding potential through Power Play and Mystery reveals,
-
And a customisable experience through gamble options,
…it’s a solid choice for fans of Rainbow Riches, Fishin’ Frenzy Megaways, or other feature-focused UK-style slots.
