Where Shamrock Riches sits in Castle Hill Gaming's range
Castle Hill Gaming lists 6 denominations for this title. Denomination is one of the strongest predictors of theoretical return on a casino floor — penny games generally carry a lower percentage than dollar games, across essentially every manufacturer.
Mechanically it is a 5 reels game. Pay-line games award only on defined line patterns, which typically means fewer but larger hits than an equivalent ways-to-win title.
Why Shamrock Riches doesn't have an RTP in the usual sense
This machine is designated HHR — historical horse racing. Despite the reels on the screen, it is not running a slot maths model at all: each play is a parimutuel wager settled against the archived result of a real horse race that has already been run, with identifying details stripped out.
That distinction is what lets these machines operate in states that never legalised slot machines — Kentucky, Virginia, New Hampshire and Wyoming among them. It also changes where the money comes from: payouts are funded from a wagering pool shared with other players, not from a fixed theoretical return set by the manufacturer.
So the honest answer is that the return depends on the pool and the takeout rate the operator applies, not on a par sheet inside this cabinet.
Reels, symbols and bonus animations on an HHR machine are a presentation layer over the race result. Castle Hill Gaming builds the cabinet and the presentation; the wagering system underneath is regulated as parimutuel racing.
