The CKM angle $\gamma$ is the least well-known angle of the Unitarity Triangle, and the only one easily accessible at tree level. Important constraints on \g are obtained from the analysis of $B^{\pm} \to D^{0} K^{\pm}$ decays, where the $D^{0}$ meson is reconstructed in the $K^+ K^-$ or $\pi^+ \pi^-$ final states; the latest world-best results using the Run 1 (2011 and 2012) and Run 2 (2015 and 2016) LHCb datasets are presented here. The measurement of $B^{\pm} \to D^{*0} K^{\pm}$ decays using a partial reconstruction method is also performed at LHCb for the first time, where both $D^{*0} \to D^{0} \pi^{0}$ and $D^{*0} \to D^{0} \gamma$ decays are considered. Both sets of results contribute to the ultimate goal of degree level precision on $\gamma$, via the exploitation of all possible channels and techniques.
