## What is Spinforge?

Build tennis racket setups for different player styles and court conditions. Adjust string tension, frame weight, balance, head size, and grip size, then run simulated hitting tests to see the impact of each choice. The system calculates control, power, spin, comfort, and wrist overload risk based on your configuration. Player orders create practical goals and force tradeoffs between performance and safety. Refine each setup through repeated testing, analysis, and correction. Unlock advanced materials and professional-style templates as you complete more precise builds.
