Prism Mine

Light a beam into the dark mine. Where it comes out, and in which colour, tells you where the gems are hiding.

  1. 1
    Send beams

    Tap a number on the edge: a beam of light goes in, bounces off the gems and comes out somewhere, coloured by every gem it touched.

  2. 2
    Sketch the mine

    You know which gems are hidden. Place them on your sketch: it tells you which beams it already explains.

  3. 3
    Give your answer

    When your sketch explains everything, submit it. Fewer beams, better score.

Your opponent will see it in online duels.
