Wish Upon A Leprechaun Slot Review
A leprechaun in a green coat leans out of a tree stump beneath a red-tiled roof, a black lantern swinging beside him, and behind him stretches the glossiest Irish glade this side of a storybook. This is Wish Upon A Leprechaun, a Blueprint Gaming slot on a 5×3 grid running at 92.56% RTP. Its argument is that none of that matters much: almost everything worth having arrives at random, from two systems that can interrupt any spin.
What makes it interesting isn’t the reels, which are plain. It’s the randomness: five board-rewriting modifiers that can fire on any spin, no scatter required. Blueprint rebuilt this game as a Megaways slot in 2019, and that version is the sharper one; the original keeps things its successor dropped. It sits in Blueprint’s Irish stable alongside Luck O The Irish Big Bonus and Irish Frenzy.
How the Base Game Pays
Wins pay as multiples of the total bet, and the top of the table belongs to the WISH UPON A LEPRECHAUN logo, which lands super stacked on the reels. It shares its values with the wild, which substitutes for everything except the Bonus symbol and can itself form winning lines. Here’s the full ladder:
- WISH UPON A LEPRECHAUN logo or Wild – 20x for two, 400x for three, 1,000x for four, 5,000x for five
- 7 or Hat – 200x for three, 800x for four, 3,000x for five
- Horseshoe or A – 100x for three, 600x for four, 2,000x for five
- K or Q – 80x for three, 400x for four, 1,000x for five
- J or 10 – 40x for three, 100x for four, 500x for five
Those top-value lines are the biggest static pays in the game. They’re also rare, which is the honest shape of a slot like this: the base game exists to keep the meter ticking while you wait for something random to happen.
The royals tell the same story in miniature. A full line of Ks or Qs returns 1,000x the bet, the same as four of the top logo – respectable, but it’s the ceiling on an unremarkable spin.
Two things break that rhythm. Three pot of gold Bonus symbols in view award the bonus outright, and the Bonus symbol pays nothing on its own. Everything else, as often as not, comes unannounced.
Lucky Charms Bonus
The Lucky Charms Bonus can trigger during any game, with no warning and no scatter requirement. When it hits, it awards one of five modifiers:
- Infectious Wilds – wilds overlay the reels and turn positions wild, then the reels can respin holding every wild in place
- They Think It’s All Clover – any reel can be turned into a reel stacked full of wilds
- Colossal Spin – any three adjacent reels can merge into a single Colossal Reel while the reels spin
- Spin Streak – a winning combination respins with the trigger symbols held, repeating until the win stops improving
- Bonus Boost – extra Bonus symbols can be added to the reels
The two respin charms work differently under the hood. Infectious Wilds holds only the wilds it created and lets fresh symbols fill the rest; Spin Streak holds the winning combination itself and keeps spinning until the win stops improving. One is about building wild coverage, the other about stretching a single result.
They Think It’s All Clover is the bluntest of the five: a full stack of wilds on one reel, no respins, no conditions, no second act. Colossal Spin is its mirror image, trading wildness for size. Three adjacent reels merge into one oversized reel while the spin is still running, so the merge isn’t locked to a fixed set of reels from spin to spin.
Bonus Boost is the odd one out. It doesn’t pay anything itself; it stacks the deck for the three-in-view bonus trigger. On the reels it’s the least dramatic charm and, potentially, the most consequential.
Jackpot King
Jackpot King is the other thing that can happen on any spin. It’s Blueprint’s shared progressive system, and it works in three steps:
- Collect crowns on the reels – more crowns means a bigger total bet multiplier
- Pick from the King’s Treasure to increase the prize
- Reach the Wheel King for a shot at the progressive pots
The crown-collection stage is the gate. Every crown you gather during that stage feeds the multiplier the round eventually pays, so a crown-heavy spin sequence can be worth far more than a thin one before you’ve picked a single treasure. The King’s Treasure pick then adds a further increase on top.
The Wheel King is the final door. Spin it well and you leave with one of the progressive pots; spin it badly and you leave with the multiplier you built. Three pots sit in the header the whole session – Royal, Regal and the Jackpot King pot itself – all progressive and all winnable from the Wheel King.
The Royal and Regal pots reseed at £500.00 and £5,000.00 respectively. No stake is too small to trigger the round.
Because Jackpot King activates on any spin, this is a slot where the two random systems stack: a Lucky Charms modifier can land while you’re mid-chase for crowns, and neither system cares whether the other is running. The base game never has to be the whole story.
Our Honest Verdict
Overall Rating: 6.4/10
Playing this is a lot of waiting in a very pretty meadow. Spins tick by, the stacked logo does its work, and the whole appeal is that at any moment the game might rewrite the board in front of you – that’s the one reason to pick it, and the leprechaun knows it, sitting there grinning from his stump.
The strength is that the interruptions are genuinely varied. Five modifiers that play nothing like each other, plus a progressive chase that ignores stake size entirely, means no two sessions feel the same. The weakness is the price of admission: a 92.56% return is low, and the stretches between charms are long and thin enough that the maths quietly nibbles at whatever the surprises hand back.
This suits players who love a random event and a jackpot chase at any stake, and who don’t need the reels themselves to entertain them. Anyone who wants rich base-game play or a generous paytable will find this glade grows more grass than gold.
