Prosperity Link Slot Machine — Wan Shi Ru Yi, Cai Yun Heng Tong & All 6 IGT Themes

IGT's Prosperity Link slot machine series currently spans six distinct base-game themes, each built on the same Lock & Respin engine but dressed in a different Eastern-fortune skin. If you've seen one title on a casino floor and wondered whether the others play differently — they share core mechanics but vary enough in volatility and visual style to matter.

What Are the Six Prosperity Link Themes?

Per IGT's official press release from July 2024, the Prosperity Link family includes six base-game themes. The two that made it to US regulated online casinos first are Wan Shi Ru Yi ("may all your wishes come true") and Cai Yun Heng Tong ("may fortune continuously flow"). Those are the variants I've personally played on BetMGM and Tropicana Online in New Jersey.

The other four themes remain primarily land-based as of this writing. IGT has not publicly named all six individually in sources available to me, so I won't invent titles — but the count of six comes directly from IGT's own announcement materials.

How Do Wan Shi Ru Yi and Cai Yun Heng Tong Differ?

Both run at a published RTP of 95.92% — roughly 96% — but they carry different volatility ratings. Cai Yun Heng Tong is classified as medium volatility, meaning wins come at a reasonably steady pace. Wan Shi Ru Yi steps up to medium-to-high volatility, so expect longer dry runs between bonus triggers and bigger swings when the Hold & Spin does fire.

The other notable difference is in the Free Spins feature. Wan Shi Ru Yi includes Wild symbols that act as multipliers of up to 5× during its 10 Free Spins round — a mechanic Cai Yun Heng Tong does not share in the same way. If you want to understand exactly how that ties into the bonus structure, the full breakdown is in our guide on How to Play Prosperity Link — Mechanics, Reels & Bonuses.

Does the Theme Affect the Jackpot Structure?

No. All Prosperity Link themes share the same four-tier jackpot ladder: Mini (up to 10× wager), Minor (up to 25×), Major (up to 100×), and the linked Grand progressive. The Grand can only be won by filling all 15 reel positions with golden orb symbols during the Hold & Spin feature — theme doesn't change that math.

The Lock & Respin mechanic itself is identical across themes. Six or more Money Ball symbols anywhere on the reels trigger it; three respins reset on every new symbol collected. For a step-by-step look at how that plays out, see How Prosperity Link's Lock & Respin Bonus Actually Works.

Where Can You Play Each Theme?

Online real-money play is available in Pennsylvania, Michigan, New Jersey, West Virginia, and Connecticut via IGT PlayDigital-powered operators. Tropicana Online Casino (NJ) carries both Wan Shi Ru Yi and Cai Yun Heng Tong; BetMGM Casino is live with Prosperity Link titles in MI, NJ, PA, and WV. Land-based themes — including machines I first played at Stations Casinos in Nevada — may differ from what's available digitally.
