  Bell's inequality fundamentally changed our understanding of quantum
mechanics. Bell's insight that non-local correlations between quantum systems
cannot be explained classically can be verified experimentally, and has
numerous applications in modern quantum information. Today, the CHSH inequality
is probably the most well-known Bell inequality and it has given us a wealth of
understanding in what differentiates the classical from the quantum world. Yet,
there are certainly other means of quantifying "Bell non-locality without
inequalities" such as the famous Hardy's paradox. As such, one may wonder
whether these are entirely different approaches to non-locality. For this
anniversary issue, we unify the perspective of the CHSH inequality and Hardy
Paradox into one family of non-local games which include both as special cases.
