24K Gold ShamRock On! Slot Review
Under scaffold towers and banks of white stage lights, on a forest boardwalk somewhere in Ireland, a leprechaun rock band is setting up for the night. 24K Gold ShamRock On! is that gig, and it’s a better slot for it: most Irish-themed games lean on clovers and pots of gold, but this one leans on a rhythm section. ReelPlay have put the personality in the presentation and the cleverness in the top row, where the real engine of the game sits.
The numbers back it up: 96.1% RTP, high volatility, up to 23,328 ways and a 5,863x maximum win. If the variable-ways formula appeals, Hercules 10K Ways and Atlantis 10K Ways are earlier takes on it, while Shamrock Money Pot Big Bang covers the Irish side of the family. Let’s see if the band can play.
Base Game & Features
24K Gold ShamRock On! runs on a 5×4 grid with an extra reel sitting above reels two to six, and the ways count moves between 3,072 and 23,328 as the layout shifts. Wins pay left to right on adjacent reels, starting from the leftmost one. Coinciding wins are added together, and only the highest combination counts per symbol.
Every winning symbol then explodes and is replaced by symbols dropping from above, with the top reel feeding in from the right. That’s the cascade loop, and it repeats for as long as new wins form. The hit rate of 36.19% means it fires often enough to keep the base game moving.
The WILD substitutes for all symbols except BONUS, and it appears on reels two to six only. Because the top reel adds a symbol above reels two to six but not the first, the leftmost reel stays fixed while everything to its right can change shape mid-sequence. A stack locked in over reel six can help complete a win that the first reel started, which is exactly the kind of chain the cascade mechanic is built to feed.
Top Row Stack
This is the engine’s signature move, and it’s tied to the BONUS symbol. Whenever one lands, the symbol directly above it in the top row turns into a stack of three identical symbols. If the symbol above happens to be Jimi O’Rock, the bandleader himself, the whole stack goes wild.
During cascades, any position that has become stacked stays stacked for whatever symbol lands there next. So one well-placed BONUS can keep paying across several chained wins. WILD, BONUS and the royal symbols never appear in the top reel, which keeps the stacks focused on the premium band symbols.
The five band members each play a role in the presentation as well as the pays. Jimi O’Rock shreds the guitar, Conner Funk holds down the bass, Paddy Snare drums, and Roxy Emerald fronts the band as the voice of the night. Jimi is the one to watch mechanically: he’s the only symbol whose top row stack turns wild in the base game.
Paytable
The band members are the premium symbols and the royals fill out the low end. Values below are at the game’s default 1.20 stake, shown for six, five, four and three of a kind:
- Top band symbol: 4.00 / 2.80 / 2.00 / 1.60
- Second band symbol: 3.00 / 2.40 / 1.80 / 1.40
- Third band symbol: 2.80 / 2.00 / 1.60 / 1.20
- Fourth band symbol: 2.40 / 2.00 / 1.60 / 1.20
- Fifth band symbol: 2.40 / 2.00 / 1.60 / 1.20
- Royals, top tier: 1.60 / 1.20 / 0.60 / 0.40
- Royals, mid tier: 1.60 / 1.20 / 0.60 / 0.40
- Royals, low tier: 1.60 / 1.20 / 0.60 / 0.40
Two things jump out of that list. The band symbols cluster tightly together, so there’s no single runaway premium symbol the way many games have. And the royals all pay identically, which flattens the bottom of the table – the difference between a bad spin and a decent one comes from how many band members show up, not which royal landed.
Note the shape of the premium rows, too: the top symbol pays 4.00 for six but only 1.60 for three, so the shorter combinations barely register. Six-of-a-kind band wins are where the cascade chains earn their keep, and with up to 23,328 ways in play those long combinations come round more often than the paytable’s modest top figure suggests.
24K Gold ShamRock On! Free Spins & Bonus Features
Feature Triggers at a Glance
- Any single BONUS symbol: triggers a Top Row Stack
- Three or more BONUS symbols: awards the Free Spins Feature
- Three or more BONUS symbols during free spins: adds five further spins
- BONUS Buy: 80x bet, spin guaranteed to carry at least three BONUS symbols
Free Spins Feature
Land three or more BONUS symbols anywhere at the end of a spin sequence and the Free Spins Feature begins with 10 spins. The BONUS symbol only appears on reels two to six, so the leftmost reel is out of the equation. Free spins play at the same stake as the triggering spin.
Inside the feature, the Top Row Stack becomes the whole show. Any stack position that occurs is held for the remainder of the round, so the top row gradually fills with locked stacks as the spins roll on.
When a BONUS symbol lands on a reel that already has a Top Row Stack, that stack turns gold and functions as a wild. A gold-transformed symbol persists through future cascades until it’s used in a win, though new symbols arriving on that position don’t transform again. It’s a ratchet: the round gets richer the longer it runs.
The sequence inside a single spin tells the story. A BONUS lands on a stacked reel and the stack goes gold; the next win involving it consumes the wild, the cascade refills the position, and any stack that was already there stays put.
Then another BONUS can land elsewhere, a fresh stack forms, and the top row inches closer to full coverage. Every additional wild above the grid is another reel that can complete a payline it couldn’t before.
Retriggers are live too. Three or more BONUS symbols finishing a spin sequence inside the feature adds five further free spins, so a lucky reel can keep the band on stage well past the original ten.
Bonus Buy
Players can skip the queue and buy straight into the Free Spins Feature. The price is 80x the current bet per spin, and every purchased spin is built to carry at least three BONUS symbols, so the feature lands each time. At the default 1.20 stake that works out at 96.00 a buy.
What the buy doesn’t do is pre-load the top row. A purchased feature starts from the same empty top row an organic trigger does, so the full ratchet still needs to be built spin by spin. The purchase buys entry, not a head start.
Our Honest Verdict
Overall Rating: 7.8/10
Playing it feels like watching a support act build to a headliner: the first few minutes are pleasant enough, and then things start stacking up and you remember why you bought a ticket. One BONUS symbol can quietly turn into a run of cascades, and the top row does more work per spin than any leprechaun has a right to. The reason to pick it is the free spins, which turn the whole engine loose.
That round is the best thing here. Stacks that hold and go wild one reel at a time mean a good session snowballs instead of resetting, and five-spin retriggers extend the run at exactly the moment it’s getting good. The weakness is the paytable underneath: the symbol pays are small relative to the stake, so between features the wins feel thin, and with high volatility those gaps can stretch.
It’s a good fit for anyone who likes a cascade game with a slow build and doesn’t mind waiting out the quiet stretches. If steady regular wins are what you’re after, this band will test your patience. Everyone else should find plenty to enjoy once the amps are on and the top row starts filling with gold.
