We don't have any actual system requirements figured out, Sort the Court is a pretty minimal program so it should run fine on most PCs. It's made using the Unity game engine, which lists their minimum requirements as follows:
OS: Windows 7 SP1+, macOS 10.11+, Ubuntu 12.04+, SteamOS+
Graphics card with DX10 (shader model 4.0) capabilities.
CPU: SSE2 instruction set support.
Best way to know for sure is just to give it a try! :)
