What BillyGo is
BillyGo is the proving ground for mastery: billiards learning with camera-based form coaching. On-device AI reads your stance and stroke against objective criteria and coaches you in real time; pattern drills, matches, and challenges track your growth. The same architecture is a framework for capturing the tacit knowledge of master practitioners.
What GEM is. GEM is a reward point earned only through learning and genuine participation. It cannot be purchased with cash, cannot be exchanged or withdrawn for cash or crypto, and cannot be transferred between users ("three gates closed"). GEM has no cash value and is not a cryptocurrency, security, or investment.
