Hey, I’m John and CurlingWorks is just me. I’ve been nurturing curling software and technology ideas for decades, since writing the classic Granite and Granite 2 games in the early 2000s.

Granite 3 is the long-delayed sequel modernized with smarter AI, even better physics, better graphics, and built for mobile (desktop coming later). It was released in early 2026.

I have other products and learn-to-curl content in the queue. Watch them in the 2026/27 curling season.
