Temple Chain Reaction

The beam travels in straight lines and turns ninety degrees at each mirror. Tapping a mirror flips it to its other diagonal and costs one of your six moves. Stone blocks stop the light dead, and every crystal the beam passes through lights up. Light them all and the temple door opens.

Each puzzle has a par, the fewest flips that solve it, and finishing on par earns three stars. Everyone gets the same temple on a given day, so results can be compared with friends using the share line at the end. After the daily puzzle, practice temples are generated at random.
