How do I play?
Tap a mirror, splitter or prism to turn it. Light travels from the brass emitters; every lantern must receive exactly the colour shown on its ring. Red and green light together make amber, red and blue make violet, green and blue make cyan, and all three make white.
What do the stars mean?
Every lighthouse has a par: the fewest taps that solve it. Finish on par for three stars. Using a hint caps that lighthouse at two stars, and you can replay any time.
What is the Daily Lighthouse?
A new board every day at midnight UTC, the same for every keeper. Light it on consecutive days to grow your streak.
Will I lose my progress?
Progress is saved on your phone. Deleting the game removes it, and Settings → Reset progress erases it on purpose.
