3 Lucky Rainbows Pros & Cons
3 Lucky Rainbows delivers classic Aristocrat action with a proven track record. The choice-based free spins and stacked symbols create a good variety, but the RTP and max win won't impress everyone.
- High RTP: At 96.47%, it is above the 2025 industry average.
- Feature Stacking: Mathematically possible to trigger all 3 features at once.
- Balanced Math: Medium volatility prevents rapid bankroll depletion.
- Multiple Bonus Modes: 3 distinct math models for free spins.
- Collection Fatigue: You cannot "buy" the bonus; you must grind for coins.
- Generic Theme: Visually, it brings nothing new to the genre.
- Max Win Cap: 5,000x is decent but won't attract jackpot hunters.
- Soundtrack: The audio loop is short and repetitive.
3 Lucky Rainbows Introduction
The market is absolutely flooded with Irish-themed games. It takes a lot for a leprechaun game to impress the data team here at SlotsGamblers.
But 3 Lucky Rainbows, developed by SpinPlay Games (a Global Games partner), attempts to stand out not with theme, but with math. Specifically, it uses the "Action Boost" mechanicâa fancy term for a triple-pot collection system that drives the entire volatility model.We tested the math model behind the rainbows to see if the pots are just visual decoration or if they actually impact the hit frequency.
Is the 3 Lucky Rainbows slot a calculated risk worth taking, or is it just another clone? Let's look at the numbers.

Symbols & Payouts

đ° BONUS FEATURES: THE ACTION BOOST
The complexity of the math model shines here. When the feature triggers, you get one (or a combination) of the Action Boost modes. This is a significant step up from standard free spins.
Green Pot: Expanding Reels Action Boost
When triggered, the grid expands from 5x3 to 5x6.
- Paylines:Â Increase from 20 to 40.
- Volatility Shift: This mode focuses on "quantity" of wins. The wilds essentially become more valuable because they have more real estate to connect. It's the most common trigger we observed during testing.
Red Pot: Jackpot Action Boost
This is the high-variance mode. It adds Gold Coins to the reels.
- Mechanic: collecting coins can award a specific jackpot color.
- Prizes:
- Mini: 10x
- Minor: 50x
- Major: 500x
- Mega: 5,000x
- Analysis: The math suggests the Mini and Minor are frequent, serving to prolong the bonus, while the Mega acts as the game's hard cap.
Purple Pot: Multiplier Action Boost
This mode applies a random multiplier to every spin.
- Multipliers:Â 2x, 3x, or 5x.
- Math Impact: This is where the line wins actually matter. A 5x multiplier on a full line of high-paying symbols is how you achieve big non-jackpot wins.
The "Combo" Trigger:
The statistical "Holy Grail" of 3 Lucky Rainbows is triggering two or three pots simultaneously. If you land a Red Coin and a Purple Coin on the same spin, and the RNG determines both trigger, you play Free Spins with both the Jackpot chance and the Multiplier active. This stacking probability is low, but it holds the highest expected value (EV) in the game.
đą MOBILE PERFORMANCE
We ran the 3 Lucky Rainbows slot through our standard mobile testing suite on both iOS and Android devices.
Orientation
The game defaults beautifully to Portrait mode. The 5x3 grid sits at the bottom, leaving plenty of room at the top for the three large Pots.
UI Scaling
The spin button is thumb-friendly.
Performance
No lag was detected during the reel expansion animation in the Green Bonus. The HTML5 coding ensures it runs lightly on browser caches.
đĄ STRATEGY & TIPS
Since you cannot overcome the house edge, "strategy" here refers to bankroll management based on the math model.
Bet Sizing for Collection
Because this is a pot-collection style game, you should play long enough to see a trigger. Don't bet 5% of your bankroll per spin. Aim for 0.5% to 1% to ensure you survive the volatility swings.
Don't Chase the Visuals
The pots grow larger visually as you collect coins. SlotsGamblers must warn you: Visual pot size does not equal trigger probability. A full-looking pot is not "due" to hit. The odds are constant on every coin.
Session Length
Due to the 29% hit frequency, aim for sessions of at least 200 spins to statistically normalize your results and likely see at least one Action Boost.
Responsible Gambling
Never chase losses. If the pots aren't popping, walk away. Set a hard limit before you open the game.
Play Responsibly - 18+ Only
Gambling should be entertaining and fun. Remember that slots are games of chance, and there's no guaranteed way to win. Never gamble more than you can afford to lose, and always set limits for yourself. If you feel gambling is becoming a problem, please seek help immediately.
FAQ - Frequently Asked Questions
What is the RTP of 3 Lucky Rainbows?
The theoretical RTP is 96.47%. This is considered above average for online slots in 2025. However, always check the game rules at your specific casino, as some operators can request lower settings.
Can I buy the bonus round in 3 Lucky Rainbows?
No, this game does not feature a Bonus Buy option. You must trigger the features naturally by landing Coin symbols that activate the Red, Green, or Purple pots.
How do I win the 5,000x Max Win?
The max win is technically achievable in the Red Pot Action Boost (Jackpot feature). If you collect enough letters/symbols to fill the Mega Jackpot meter during the bonus, you win the 5,000x prize immediately.
Do the pots guarantee a win when they look full?
No. The graphical size of the pot is purely for visual excitement. The mathematical chance of triggering the bonus is determined by the RNG the moment a coin lands, regardless of how "full" the pot looks.
Is 3 Lucky Rainbows high volatility?
We classify it as Medium volatility. This means the payouts are fairly balanced between small base game wins and larger bonus wins, making it suitable for most bankroll sizes.
What does the Green Action Boost do?
The Green bonus expands the grid to 5 reels and 6 rows. This increases the paylines from 20 to 40, giving you more ways to win and more space for Wild symbols to connect.
Can I play 3 Lucky Rainbows on mobile?
Yes, the game is fully optimized for mobile play using HTML5 technology. It works seamlessly in portrait mode on both iPhone and Android devices without needing an app.
Is this game better than 9 Pots of Gold?
From a math perspective, SlotsGamblers rates it slightly higher due to the higher max win potential (5,000x vs 2,000x) and the variety of bonus features, though 9 Pots of Gold is simpler to understand.
