SpinGreen

SpinGreen is a casino game math preview platform that transforms mathematical specifications into instant, playable browser prototypes. Game studios, designers, and producers can test their slot game mechanics—including rhythm, volatility, and feature feel—before commissioning art or writing client code.

The platform solves the communication gap between math designers and game engine teams by eliminating weeks of waiting to physically experience a game model. Users simply upload reel strips and paytable JSON to instantly generate shareable, read-only prototype URLs with real-time telemetry inspection. Features include zero client dependencies, support for multiple grid configurations (5×3, 5×4), configurable spin speeds, and detailed session analytics tracking RTP, hit frequency, and payout data.

Designed for rapid iteration and team collaboration, SpinGreen requires no credit card or login, enabling studios to validate game feel and make critical design pivots before full production begins.
