Why use it
Use OpenSpiel to formalize rules to test strategy spaces, equilibria, and agent behavior instead of relying only on human intuition.
Where it fits
Use prototypes and playtests to find core experience problems while they are still cheap to fix.

What to check
It is a C++ and Python research library, not a visual designer, so modeling has a high entry cost; simulation results depend on rule abstractions and algorithm assumptions.
