Game Model Score Limits
Limits to values returned by the Score(for:) method.
Overview
When you evaluate the state of a game model in the score(for:) method, the GKMinmaxStrategist class weights the resulting value by search depth and performs other calculations in its process of selecting an optimal move. To prevent overflow errors in such calculations, keep scores within the range of GKGameModelMinScore to GKGameModelMaxScore, inclusive.
