Super Diamond Deluxe

A progressive jackpot on a five-reel diamond grid — Super Diamond Deluxe runs Blueprint's Jackpot King-style pooled layer over the most traditional symbol set in the business. The mechanic is the argument: gem classicism with one modern hook.

How the diamond cuts

Five reels under diamond-and-gem theming, released 4 October 2017. Blueprint Gaming — 365 titles in our index — keeps this build deliberately clean: no Megaways, no cascades, the pool carries the excitement. Nine years on, the formula hasn't needed a redesign.

Math with a verified spine

RTP is 96.43%, and it carries verification from us because two independent feeds file it to the hundredth. That clears the 96.08% median of our sample by 0.35 points, solid for a jackpot-linked game, where pool funding usually drags return down. Volatility splits the sources: slot.report says "medium," our grade says 5 of 6. Budget for the harsher reading.

The deluxe demographic

A 2017 build still earning a page in 2026 is its own kind of evidence, though not the numerical kind. The fit is a player who wants verified above-median math and jackpot eligibility in one machine, and who accepts that the volatility question is genuinely unsettled. The demo settles it experimentally, for free.

Even a verified 96.43% leaves 3.57 house-side over time — diamonds are forever, bankrolls aren't. Set the ceiling first. 18+.
