SpinGreen

SpinGreen is a developer tool that transforms casino game math specifications into instant playable browser prototypes. Designed for game studios, designers, and producers, it eliminates the communication bottleneck between math designers and client engine teams by allowing teams to test and feel game rhythm, volatility, and feature behavior before writing any client code or commissioning art.

The platform accepts reel strips and paytable JSON, providing zero-dependency prototypes with shareable read-only URLs and real-time telemetry inspection. Users can instantly test different bet amounts, spin speeds, and gather session data including RTP, hit frequency, and dry streaks to validate whether the game feels rewarding and meets design goals.

SpinGreen solves a critical pain point in game development where theoretical math models and disconnected spreadsheets cannot convey player experience. With turnaround times under 15 minutes and no login required for sharing, it enables rapid iteration and cross-team validation of slot game mechanics.
