  A brief overview of flavour-symmetry strategies to extract the angle gamma of
the unitarity triangle is given, focusing on B --> pi K modes and the B_d -->
pi^+ pi^-, B_s --> K^+ K^- system. We discuss also a variant of the latter
approach for the e^+ e^- B-factories, where B_s --> K^+ K^- is replaced by B_d
--> pi^{+/-} K^{+/-}.
