Leprechaun's Vault Slot Overview
Leprechaun's Vault is a 5x3 video slot from Play'n GO running on 20 fixed paylines. Released on 4 August 2022, it follows the story of Larkin the Leprechaun, whose vault keys have been stolen by mischievous fairies. From a math perspective, you get a default RTP of 96.20%, high volatility and a 9,000x max win. Bets range from 0.20 to 100 per spin.
Core mechanics centre on Multiplier Wilds, Treasure Free Spins and a Vault cylinder feature that determines your free spin count before the bonus begins. It is the fourth entry in Play'n GO's leprechaun-themed series, following Leprechaun Goes Wild, Leprechaun Goes to Hell and Leprechaun Goes to Egypt.
Symbols and Paytable
Low-paying symbols are 10, J, Q, K and A, returning between 1.25x and 2.5x for a five-of-a-kind line. Medium symbols include a horseshoe (6.25x) and a hat (5x). Four character symbols sit at the top: three fairies in turquoise, purple and yellow, plus Larkin himself in green. Five Larkin symbols pay 37.5x the bet, making him the most valuable standard icon on the grid.
A money bag acts as the wild, and a golden key is the scatter. The numbers tell you that the paytable is top-heavy; there are many different symbol types spread across only 20 paylines, so landing five-of-a-kind is tough in practice. I find the gap between lows and highs quite steep, which suits the high-volatility profile but can make the base game feel dry.

Bonus Features Breakdown
Multiplier Wilds appear exclusively on reels 2, 3 and 4 during both base and bonus play. Each wild carries a random 2x, 3x or 4x multiplier applied to every winning combination it helps form. Because they cannot appear on the outer reels, building full-line wins with multiplied wilds requires favourable adjacent symbol placement. Restricting wilds to three reels does limit potential; I would have preferred at least occasional wild appearances on reels 1 or 5.
Landing 3 golden key scatters on reels 1, 3 and 5 triggers Treasure Free Spins. Before the spins begin, the Vault feature activates. You spin 4 separate cylinders, each awarding between 2 and 6 free spins, giving a total of 8 to 24. During the bonus, all Multiplier Wilds that land become Sticky Wilds and remain locked for the rest of the round. Scatters do not appear in the bonus, so retriggers are off the table.
From a math perspective, the sticky wild accumulation is the primary win driver. A long free spins run of 20 or more spins gives you realistic chances to fill reels 2-4 with multiplied wilds and chase the 9,000x cap. Short runs of 8 spins, however, rarely build enough sticky coverage to produce meaningful payouts.
Bonus Buy Options
Triggered by landing 3 scatter symbols on reels 1, 3 and 5. During the bonus, multiplier wilds become sticky on reels 2-4 for the remaining spins. No scatters land during the feature, so retriggers are not possible.
Activated before Treasure Free Spins begin. Four cylinders are presented, each awarding 2 to 6 free spins, resulting in a total of 8 to 24 free spins.
Wild symbol that substitutes for all symbols except scatter. Displays a 2x, 3x or 4x multiplier applied to any winning combination it participates in. Appears only on reels 2, 3 and 4 in both base and bonus games.
RTP, Volatility and Max Win
Default RTP sits at 96.20%, which is competitive within the Play'n GO catalogue. Operators can select lower configurations of 94.20%, 91.20%, 87.20% or 84.20%, so always verify the setting at your chosen casino. High volatility means extended losing streaks between significant hits; the 9,000x ceiling is slightly below Play'n GO's typical average for this tier, but still within a solid range for session potential.
