Triple Action Dragons

Why Triple Action Dragons 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. Ainsworth builds the cabinet and the presentation; the wagering system underneath is regulated as parimutuel racing.
