Game: Jewel Thief

Anyone who's bought a diamond wedding ring, or seriously contemplated its implications, is familiar with the Four C's - carat, color, clarity and cut. In simplest terms, the larger the weight, the purer the color, the more flawless the stone and the better its proportions, the higher its quality and more stratospheric its cost. Jewel Thief, a gem-based puzzler, offers the game equivalent of a rare diamond. All facets of its creation work together to make it a stand out. The clincher? It can be had for the price of a cubic zirconia.
