Spin Joy Games Built 'Buffalo Tornado' for the US Market — and Sweepstakes Lobbies Embraced It
The studio's Wild West slot wasn't designed for a wrapper. Its organic traction — including at SweepKing — is exactly why Spin Joy Games thinks adaptable content, not any single model, is where the durable value in the shifting US market now sits.
When Spin Joy Games built Buffalo Tornado, it wasn't chasing a wrapper. It was building for the American market, where the buffalo-style slot is one of the most reliable formats there is. What the studio didn't plan for was how cleanly the title would travel once it was live — including into sweepstakes, where it has found a strong audience in SweepKing's lobby. That organic pickup, Spin Joy argues, says more about where the US market is heading than any deliberate "sweepstakes strategy" could.
The consensus story says sweepstakes is dying. Montana banned the dual-currency model in 2025, California followed with Assembly Bill 831 — reaching content suppliers and payment processors, not just operators — and New York banned it weeks later. Seven states had prohibited it by early 2026; Illinois alone sent 65 cease-and-desist letters in May. Pragmatic Play, the category's biggest supplier, exited the US sweepstakes market entirely.
Spin Joy Games reads it differently, and Buffalo Tornado is why. Strip out the coins and US demand is enormous: Eilers & Krejcik put sweepstakes net revenue near $3.4bn in 2024 — comparable to the gross gaming revenue of the entire regulated US online casino market — from a footprint of forty-plus states against roughly eight where real-money casino is legal. Ban California and you remove up to a fifth of category revenue, not the players who generated it. The demand is structural, and it's strong enough to pull the right content across wrappers on its own.
"We built Buffalo Tornado for the US market, not for a specific model", says Mariia Gruzan, Head of Partnerships at Spin Joy Games.
"Then we watched where it landed — and one of the places it landed hardest was sweepstakes. That's the signal, not the exception."
The game is a case in point precisely because it wasn't engineered for the wrapper it found. It's a 5×3, 243-ways slot built on one of the most durable archetypes in the category — the Wild West buffalo format — with battling Wild multipliers, a global bonus mechanic, and a Buy Bonus option. Released in April 2026 at a 92% RTP with a top win of around 2,300x, it was designed to do what buffalo-style games reliably do on the American market: feel familiar on sight, and deliver a high-ceiling prize chase. Once it was live, sweepstakes players did the rest.
For Gruzan, that's the strategic point:
Our content is built to be configured for whatever an operator runs — sweepstakes, crypto or regulated real-money — but we don't design a title for one of them,
she says.
That's exactly why a game we made for the US market could land in a sweepstakes lobby without us re-engineering it. When suppliers are pulling back, being present wherever the demand shows up is the whole game.
Where it showed up is telling. SweepKing went live in September 2025 — into the teeth of the crackdown, not away from it — and now runs around 1,700 titles from roughly 20 studios with a full responsible-gaming toolkit.
An operator that launches while the biggest names are retreating is telling you where it thinks the demand is, Gruzan says. Seeing our game find an audience there just confirmed it.
Buffalo Tornado sits within a wider Spin Joy catalogue — including KAPITO Gaming reskins — running on the studio's own RGS and aggregation platform, and Spin Joy also builds bespoke, operator-exclusive titles under direct deals. Where content sits in an open lobby, the commercial model stays deliberately simple: a straight 70/30 revenue share weighted to the operator.
"When margins are already squeezed by compliance cost, operators don't want a complicated deal on top of it" Gruzan says.
"Flexible on the wrapper, simple on the split."
The ban headlines will keep coming, and each will read as another nail. It's the wrong frame. The demand that pulled Buffalo Tornado into a sweepstakes lobby isn't going anywhere — it's just choosing its wrapper. And content that doesn't care which one wins gets to be there when it does.
