I'm a big fan of puzzle games on my Android. They tend to work well in a touch-controlled medium because their concepts are usually simple enough to pick up and play. Refraction is no different, and challenges players with over 120 levels of color-matching, light-bending goodness that will have even the smartest of you scratching your head for awhile.
Like every good puzzle game, Refraction starts out with a simple concept: use mirrors to guide beams of light to their corresponding beacons. It then adds another element in prisms, which allows for the splitting and combination of colors. Combining a yellow and red beam in a prism will produce orange, and running that beam back through a prism will break it back into its original components.
