About the game

How Prism works,
in short.

  1. Step 01

    Bend a beam.

    Each puzzle starts with a colored light source firing a beam straight across the grid. Tap a mirror to rotate it; the beam bounces 90° off the new diagonal.

  2. Step 02

    Split it in two.

    A splitter lets the beam continue forward and sends a perpendicular copy off the diagonal. Each branch is half the intensity — split twice and a target may not light.

  3. Step 03

    Combine the colors.

    Red plus blue makes magenta. Aim two beams of the right colors at the same target and the target lights when the colors add up to match.
