Despite huge advances made by both B-factory and Tevatron experiments, the angle gamma remains the least well measured parameter of the CKM unitarity triangle. One of the unique charms of this angle is that it can be measured in a way which is theoretically clean and free of physics effects beyond the Standard Model. With the recent startup of the LHCb experiment, powerful new methods of constraining gamma are becoming available based on decays too rare to be abundantly observed at previous measurements, and they will be presented here. The combination of these results into an LHCb value for gamma is discussed, as is the interplay with other experimental results and inputs. Finally some crystal-ball gazing is indulged in order to guess what the road towards a precise gamma measurement might look like.
