The box cover for Prism makes it seem too much for kids but it is actually a fun brain teaser for any age. You have to line up mirrors, light beam splitters and colored filters to direct a ray of light at a colored target set in a maze. For variety, there are several different playing modes (casual puzzling, timed, hyper, etc) but for me, the puzzles are more fun to contemplate rather than than race to solve. I didn't give it 5 stars because it is not shoot em up, Super Mario-esque fun, it is more like solving a visual soduku. I'd also give it a higher score if it used different pieces and "worlds" rather than just increasing complexity on an evolving playing field. Bottom line: The satisfaction comes from solving the brain teasers not from an adrenaline rush.
