Where Mighty Diamonds - Jolly Leprechaun sits in Sega Sammy Creation's range
Mighty Diamonds - Jolly Leprechaun is part of Sega Sammy Creation's Mighty Diamonds line, which runs to 9 documented titles. Manufacturers ship a hit as a family rather than one box, so entries in a series share branding and often a bonus structure while carrying different maths.
It is listed on the GENESIS CREST cabinet. The cabinet is the hardware — screen geometry, button deck, chair and speakers — and the same title is frequently released on more than one, which is why a game can look and feel different at two properties.
Sega Sammy Creation lists it as a progressive. That does not make it a wide-area jackpot: most progressives build from play on that machine or that bank of machines inside one property, and reset locally. The wide-area systems — the ones where a meter is shared across dozens of casinos — are a much smaller, separately licensed set.
What's the RTP of Mighty Diamonds - Jolly Leprechaun?
There isn't one number — and any site quoting you a single figure is describing a different product.
Manufacturers ship the same title in multiple par versions, commonly spanning roughly 85% to 96%. The casino chooses which one to install, and that choice is not disclosed on the machine. Nevada regulation only sets a floor: every wager must theoretically return at least 75%.
What regulators actually publish is hold percentage — realised performance after player behaviour, aggregated by region and denomination. It is never broken out by game title. So the honest answer for any land-based machine is a range plus an unknown configuration, not a single figure.
Figures quoted elsewhere for this title are almost always taken from its online version, which is a different product with a different maths model.
Where to play
We don't yet have verified floor placements for this machine. Our casino cross-reference covers 442 properties, but only through IGT's public linked-progressive data — which doesn't reach Sega Sammy Creation titles. We would rather show nothing than guess.
