Executive summary

A decade-old franchise at the top of its maker's portfolio. Dragon Link is, in the words of Aristocrat's own chief revenue officer, "arguably the most successful product ever in the history of gaming in terms of slot machines." It was designed by High Roller Gaming, the Aristocrat studio that built Lightning Link, and launched in Australia in 2016, in North America in December 2017 and in Asia from 2022. Aristocrat called it the number-one premium game family in North America in 2020, reports players in more than twenty countries, and in August 2026 marked ten years in market; in June 2026 it was named Casino Product of the Year at the Global Gaming Awards Asia. The Seminole Hard Rock in Hollywood, Florida paid its largest jackpot, $2,856,079 on a $250 bet, in December 2024 — 11,424 times the wager and a record in Aristocrat's history.

Ten themes, one engine, five free-game designs. Every Dragon Link title runs the same Hold & Spin feature, triggered by the same Orb, paying the same four-tier jackpot ladder. What changes from theme to theme is the free-game feature, and the ten themes use exactly five designs, each shared by two titles: stacked premiums with the royals removed; mystery symbols that all reveal the same symbol; a three-by-three "big reel" formed when reels 2, 3 and 4 spin as one; wilds that carry a ×2 multiplier and compound to ×16; and wilds that expand to cover the reel. Those are the expanding wilds, the center square and the 2× symbols players describe. Section 4 sets out each one; Section 1 maps the ten themes onto the five designs.

None of the mathematics is published, and a federal court has said why. Aristocrat publishes no paytable, no return figure, no hit frequency and no trigger rate for any Dragon Link title in any channel. In its 2024 suit against Light & Wonder it identified exactly those figures — the percentage of wagers returned, the volatility, and "the combinations, pathways, and probabilities" for triggering Hold & Spin — as trade secrets. The court found Aristocrat "extremely likely to succeed" in showing that Light & Wonder's Dragon Train was built on them, and in January 2026 Light & Wonder agreed to pay US$127.5 million, pulled Dragon Train and Jewel of the Dragon worldwide, and acknowledged that "certain Aristocrat math information was used." It puts a public price on a slot machine's mathematics, and it explains the silence.

The mathematics that is public is forum mathematics, and it holds together. Players on the Wizard of Vegas forum mapped the reel strips of an Autumn Moon game from slowed-down video and found five Orb positions per reel, one stack of three and one of two. That strip set triggers Hold & Spin once in 120.95 paid spins; an independent observed distribution on a Lightning Link sibling gives once in 136.92.27 A one-hard-cell completion model built on the same thread fills the fourteen easy positions in 8.3% of six-Orb bonuses and wins the Grand in about one feature in 1,100. Chained together they are internally consistent: at a 2% contribution rate they imply an average Grand of about $13,700, inside the $10,000 reset and the $18,888.88 cap that players report on the penny game. Every input is graded Tier 3, the chain is not fully independent, and every step is shown.

Four jackpots, two progressive — and the small two are denomination prizes, not bet prizes. The regulator in the Australian Capital Territory approved the later themes under a name that counts their progressives — "Genghis Khan – Dragon Link (1 Link + 1 iSAP)" — one linked progressive, the Grand, and one stand-alone progressive inside the machine, the Major. The Grand never appears on an Orb and, in the feature, is won only by filling all fifteen positions (early builds could also award it at random); the Major lands on an Orb at most once per feature, and on a $1 Million game in 2023 it was also paid at random on a spin that did not trigger the feature. The Mini and Minor behave as fixed awards of 1,000 and 5,000 credits of the denomination played — the pattern every published value from 1¢ to $5 fits, though no help screen confirms it — which is why a $10 Mini on a $5 penny bet is two times the wager and a $100 Mini on the same $5 bet at dimes is twenty times. The Grand's amount does not scale with the bet; its probability does.

Every Dragon Link progressive is local. The standard game links its Grand across a bank of machines; Dragon Cash, the stand-alone sibling, plays the same themes without the link; the $1 million and $2 million versions are banked by one casino or linked across one operator's own properties — three Seminole casinos in Florida in 2022, and a three-property link in Las Vegas reported as "non-wide area." No wide-area Dragon Link progressive exists in the record; Aristocrat's multi-site product is Dollar Storm. Nor is there any advantage play or perceived progression: nothing on the glass fills toward a feature, no meter must hit by a ceiling, and the only state that passes from one player to the next, the Major and Grand meters, adds value but never makes an award more likely — on the standard game both are capped and roll their overflow into the next seed (Appendix C, §C.3).

The regulator's record dates what the manufacturer leaves undated. Aristocrat's pages date nothing after the first four themes; the ACT's statutory approval instruments date the rest. Genghis Khan and Peace and Long Life were approved together on December 6, 2018, nearly six years before they became the world's first $2 Million Dragon Link; Golden Gong and Silk Road were approved together on July 30, 2020. Every theme exists in two approved versions, Dragon Link and Dragon Cash, and the games were carried onto new platform software through 2025, with a re-engineered Peacock Princess approved in March 2026. None of those instruments contains a return figure.

What the volume covers

Section 1 is the orientation: ten themes, one engine, five free-game designs, five jackpot configurations. Sections 2 and 3 cover Aristocrat, the franchise's lineage, the Dragon Train litigation, the cabinets and the jackpot controllers. Section 4 is the mechanical core — the Orb, Hold & Spin, the hard cell, each free-game design, the random awards and Lucky Chance, and every symbol documented for every theme. Section 5 is the mathematics: what is published (nothing), what can be derived from the bet structure, the forum models and a register of the bad figures in circulation. Section 6 is the variant census, with the Australian regulator's approval record. Sections 7 through 10 cover progressive jackpot structure and economics, denominations, market position and prevalence in Asia, and regulatory class and channel. Appendix A grades every source; Appendix B shows every calculation so it can be checked rather than trusted; Appendix C is the persistent-state and advantage-play register, with every display that looks like progress classified.
