SpinGreen

SpinGreen is a casino game math preview tool that converts slot game specifications into instant, playable browser prototypes. Game designers and studios can test their mathematical models, evaluate gameplay rhythm, volatility, and feature feel without requiring client code or commissioned art assets.

The platform accepts standard JSON math specs and reel strip data, generating shareable prototype URLs within minutes. Teams can conduct real-time telemetry analysis, test at various bet levels and game speeds, and gather feedback from stakeholders before investing in full engine development.

SpinGreen solves the communication gap between math designers and development teams by enabling rapid iteration on game feel and balance metrics like RTP, hit frequency, and feature triggers. The tool requires no login, credit card, or client dependencies, making it accessible for studios looking to validate game concepts early in development.
