A Megaways Take on Blueprint's Lucky Irish Theme

Irish Riches Megaways Jackpot King is Blueprint Gaming's reworking of its long-running Irish luck theme, built on the Megaways engine and wired into the studio's Jackpot King progressive network. Released in 2018, it trades the fixed reels of older Irish slots for a shifting grid of up to 117,649 ways to win, cascading symbols, and an unlimited win multiplier in free spins. The result is a game that keeps two things running at once: a feature-led Megaways base game and a separate progressive jackpot layer that can drop on any spin.

Reels, Ways to Win and Layout

The game uses the standard Megaways setup of six reels, with the symbol count on each reel changing from spin to spin. When the reels fill out completely, you get the maximum 117,649 ways to win. A horizontal reel runs across the top of the four central reels, adding extra symbol positions, which is what pushes the ways count so high. Because wins are paid on adjacent matching symbols from the leftmost reel rather than on fixed lines, there are no traditional paylines to set.

RTP and Volatility

The Jackpot King version of Irish Riches Megaways runs at an RTP of 95.93%, which sits a little under the 96% mark common to many modern slots. Part of that return is diverted to fund the progressive jackpot pools, which is typical for Jackpot King titles. Volatility is medium-high, so the swings are real: expect quieter stretches between features, balanced by larger payouts when cascades and multipliers line up. It suits players comfortable with variance rather than those after steady, frequent wins.

Cascades and the Mystery Symbol

Wins trigger cascading reels: symbols in a winning combination are removed and new symbols drop in to fill the gaps, which can chain several wins from a single spin. The signature extra is the four-leaf clover Mystery Symbol. When it lands, it reveals a single matching standard symbol across all its positions, which can turn a scattered board into a connected win. Wilds substitute for standard symbols to help complete those ways, while scatters are reserved for triggering the bonus.

Free Spins and the Unlimited Win Multiplier

Landing four scatters awards 12 free spins, with five extra spins added for each additional scatter beyond the fourth. The headline feature here is the unlimited win multiplier: it starts at 1x and climbs by one with every cascade during the round, with no cap. Because the multiplier carries across the whole feature and never resets, a long run of cascades is where this slot's biggest non-jackpot payouts come from. The maximum win is capped at 10,000x your stake.

The Jackpot King Progressive Layer

Jackpot King is Blueprint's network-wide progressive system, and it can activate at random on any base-game spin. Once triggered, you move to a separate set of reels and start collecting crown symbols. Fill enough positions and you advance to the Wheel King bonus, where you spin for cash prizes and the chance at the network progressive pots. The top Jackpot King prize is a network jackpot shared across all linked games, so its size depends on how much has accumulated across the network at the time you hit it.

Playing the Demo and Mobile
