Action Boost 3 Lucky Rainbows Slot Review
In a sunlit Irish glade, three translucent columns of green, orange and violet light rise above the reels, ghost coins drifting inside them towards a pot of gold. Those columns matter more than the reels do. SpinPlay Games have built Action Boost 3 Lucky Rainbows so the reels mostly exist to feed coins into those pots, and everything you’re actually playing for happens above them.
It runs on a 5×4 grid with 20 paylines, at 96.27% RTP and high volatility, with stakes from 0.20 to 40.00 and a hit rate of 33.68%. There’s no maximum win figure for this one, so the four jackpots are the only fixed targets. It’s the earlier, simpler sibling of 3 Lucky Rainbows Action Boost Max, with 3 Lucky Rainbows Action Boost SpinUP also in the family.
The question is whether the pot-filling is worth the wait.
Base Game & Features
The base game plays 20 fixed paylines across five reels and four rows. Wins run left to right from the first reel, and only the highest combination pays on each line. Payline wins are based on the initial bet rather than the total stake.
That split matters for reading the paytable. The initial bet is the total bet divided by the payline cost of 20, so at 0.20 total stake each line carries 0.01. Everything below is a multiple of that line bet.
- Clover: 0.5x, 1x or 5x the line bet for three, four or five
- Beer Mug / Green Shoe: 0.25x, 0.5x or 2.5x
- Harp / Violin: 0.25x, 0.5x or 2x
- A, K, Q, J, 10, 9: 0.1x, 0.25x or 1x
Five clovers on a line returns five times the line bet, which is a fraction of the total stake. The gap between the top symbol and the royals is steep, and that shape tells you where the game expects the money to come from: not the lines.
Wild Hat symbols substitute for everything except coins, and they can form their own winning combinations. The Pot of Gold Coin is the one to watch. Every one that appears collects into the pot of the same colour above the reels, and each carries a chance of setting off the features.
The animation doesn’t influence triggering; the collection does. Autoplay is available in the base game only, with loss and win limits, and Quickspin resolves spins faster without influencing the results. Both are conveniences rather than features. The coins are the real machinery here, and everything they feed sits above the reels.
Action Boost 3 Lucky Rainbows Free Spins & Bonus Features
Two things can happen when coins land, and both of them run through the same machinery. The simpler one is the Rainbow Spin: a single spin with all three rainbows active, and any coins that land on them trigger the free spins. It can also pay out one of the four jackpots directly: MEGA, MAJOR, MINOR or MINI.
The main event is the Action Boost Free Spins. One or more coins carry a chance of triggering them, and the combination of colours collected determines which of three rounds you get. They’re genuinely different games, not one bonus in three colours:
- Green Coin Action Boost: 5 free spins, 40 lines, all reels grow to six symbol positions
- Red Coin Action Boost: a 10-spin round built around the shamrock jackpot ladder
- Purple Coin Action Boost: five spins, every one carrying a random multiplier
- Multiple Coin Action Boost: 10 free spins if Red is among the triggered boosts, otherwise 5
Green Coin Action Boost
Five free spins on an expanded grid: all reels grow to six symbol positions and 40 lines are played. Every Gold Coin that appears awards a bonus credit prize or a Rainbow Spin, and the Rainbow Spin either pays a credit prize or upgrades a symbol to Clover for the remaining free spins. Upgrades apply before any wins are paid.
The nudge is the sharp end of it. Any reel holding a Wild is nudged so every position on that reel goes Wild, and wins are paid only after the nudging. On a six-high grid with 40 lines, that’s the loudest single spin the game produces.
Red Coin Action Boost
Ten free spins, and every Gold Coin awards a shamrock, a credit prize or a Rainbow Spin. The Rainbow Spin here awards shamrocks, a credit prize or a boost to a jackpot value for the remaining free spins. The shamrocks feed a four-tier ladder:
- MEGA: collect 6 Red Shamrocks
- MAJOR: five Purple Shamrocks unlock it
- MINOR: the prize for four Blue Shamrocks
- MINI: three Green Shamrocks pays it
Complete a ladder and the corresponding jackpot is awarded, then that ladder’s shamrocks reset. A single round can therefore pay the same jackpot twice, which is the sharpest detail in the whole feature set.
Purple Coin Action Boost
Five free spins with a random multiplier of 2, 3 or 5 awarded on every spin. Gold Coins here award 1 or 2 free spins, a credit prize or a Rainbow Spin, and the Rainbow Spin can pay a further 1, 2 or 3 free spins on top. The multiplier applies to all line wins and credit prizes.
Multiple Coin Action Boost
Collect several coin colours on one spin and every triggered boost runs together in a single round: 10 free spins if the Red boost is among them, 5 otherwise. The Purple multiplier applies to all line wins and credit prizes, but never to the jackpots.
That combined round, with everything running at once and a multiplier stacked on top, is the best spin this format produces. The bet multiplier in any free spins round is the same as the game that triggered it.
Our Honest Verdict
Overall Rating: 7.2/10
Playing this is a lot of watching glade sunlight while three pots slowly fill. That patient build is the whole reason to choose it: the coins you’re collecting are tickets to three rounds that behave nothing like each other, and chasing a particular colour gives the base game a purpose its paytable never supplies.
The rounds themselves are the strength, and the shamrock ladder is the best of it, because a completed ladder resets instead of closing, so one good set of spins can pay the same jackpot twice. The weakness is everything underneath: a top symbol worth a fraction of your stake per line, so the reels themselves never become interesting.
It’s for players who enjoy watching a system build, jackpot hunters, and anyone curious where the later Lucky Rainbows games came from. Players who want the spinning itself to carry the session will find the glade quiet and the pots slow to fill, and this isn’t the slot that will change their mind.
