Questions tagged [points]

A scoring system for games or algorithms. Geometric items should be tagged with coordinates or point.

This tag represents:

  • an arbitrary numerical counter for games or scoring algorithms

Please do not use this tag for:

  • a dimensional measurement for geometric calculations, such as [x, y, z] -- instead use
  • a coordinate in GPS mapping -- instead use
