I built a game for BJJ players who want to keep training off the mats.
Meet Grapple Dojo: basically “grappling chess” powered by 3D animations, featuring authentic positions and transitions.
It utilizes Eelis van der Weegen’s incredible GrappleMap dataset—which maps 843 positions and 1,485 transitions from top-tier instructionals (Marcelo Garcia, Ryan Hall, Eddie Bravo, Demian Maia, etc.), complete with exact DVD chapter/second references.
Key Features:
Active Recall: Test your positional knowledge in tactical duels.
Full 3D Viewer: Rotate and analyze moves from any angle through a White-to-Black belt curriculum.
Virtual Open Mat: Set up positions on an interactive dummy and share techniques via live chat.
Stat Tracking: Track your mastered techniques and overall rank progress.
Huge credit to GrappleMap for doing the heavy lifting with the data—I just gamified it!
Try it out and tell me: what’s your go-to position? 🤙

P.S. Still in active development! Working on tighter move validation, better 3D models, and bug fixes.
