Irish themes rarely travel light, and the one we’re discussing now is the perfect example. 3 Lucky Rainbows Action Boost Max builds on SpinPlay Games’ leprechaun series with coloured coin boosts, stacked Bonus Spin modes, and a habit of letting multiple features run at once. As is, the setup is busy, since expanding reels go hand in hand with jackpots and pick moments that interrupt the spin flow in measured ways.
The setting sticks to rolling green hills and storybook Ireland, complete with mushrooms, flowers, and a quietly glowing landscape behind the reels. While there’s no single Leprechaun to guide you through, the game leans on symbols like hats, clovers, and instruments to do the storytelling. Gold coin pots sit above the grid, filling and upgrading as play unfolds. As most Irish online slots do, the soundtrack stays in light Irish folk territory, present but not demanding attention.
The paytable follows a clear ladder from card ranks to themed symbols. Wins are paid for three, four, or five of a kind along fixed paylines.
| Symbol | Payout for 3, 4, and 5 of a kind |
|---|---|
| 9 | 0.20, 0.50, 2.00 |
| 10 | 0.20, 0.50, 2.00 |
| J | 0.20, 0.50, 2.00 |
| Q | 0.20, 0.50, 2.00 |
| K | 0.20, 0.50, 2.00 |
| A | 0.20, 0.50, 2.00 |
| Violin | 0.50, 1.00, 4.00 |
| Harp | 0.50, 1.00, 4.00 |
| Leprechaun Shoes | 0.50, 1.00, 5.00 |
| Beer Pint | 0.50, 1.00, 5.00 |
| Four Leaf Clover | 1.00, 2.00, 10.00 |
| Pot of Gold | 2.00, 4.00, 20.00 |
Coin symbols feed into coloured pots above the reels. When triggered, Action Boost Max Bonus Spins run for a fixed number of spins, with the colour and combination of coins determining which enhancements apply. Gold Coin symbols during these rounds can potentially award bonus credits, extra spins, upgrades, or even additional Action Boost features.
This mode focuses on reel expansion. The grid grows taller and paylines increase, while Wilds can nudge to cover full reels. Upgrades add more Wild presence as the feature continues, and potenital wins are calculated after all nudges resolve.
Red Coin Bonus Spins shift attention toward jackpots. Collecting clovers builds toward fixed jackpot prizes, and upgrades reduce the number of clovers needed. Each completed jackpot resets its counter, keeping progression in motion across the feature.
Purple Coin Bonus Spins introduce a multiplier that applies to potential line wins and bonus credit prizes. The multiplier starts modestly and can be upgraded twice.
When all coin types combine, all Action Boost features run together. The Purple multiplier applies broadly, while jackpots retain their own rules. Extra spins are added when new features or upgrades appear, extending the sequence without breaking its structure.
The base game uses a five reel, four row layout with fixed paylines paying left to right from the first reel. Within this setup, wins require three or more matching symbols aligned on a payline. During certain Action Boost modes, the reels expand vertically and paylines increase, changing how potential wins form without altering the underlying pay direction. Standard spins resolve line wins first, then apply any Wild nudges, upgrades, or bonus effects before moving on.
This is yet another slot that brings together Irish themes and stacked features. In case you want to try some more of the same (or similar), check out these BetVictor Casino titles:
3 Lucky Rainbows Action Boost Max feels like a conversation that keeps branching off before the last point is finished. There is always another coin to collect or another upgrade waiting to land, meaning it was designed for those of us who enjoy systems stacking on top of systems. If we’ve being honest, the visuals don’t do much in terms of novelty, but they stay clean even when several features overlap. Some moments can feel busy, yet the rules remain consistent enough to follow.
