Puzz

How to play

Goal

• Place all three lights so every dot around the border glows exactly the color it needs

Rules

• Each light shines in every direction until a black wall blocks it
• White cells are mirrors — light bounces off them instead of stopping (Hard puzzles only)
• A dot only counts as lit once it's completely covered by its color, edge to edge — half-lit doesn't count
• A Red, Yellow, or Blue dot needs light from only its own color reaching it — any other color landing there too spoils it
• An Orange dot needs both Red and Yellow (and no Blue); Green needs Yellow and Blue (no Red); Purple needs Red and Blue (no Yellow)
• Every puzzle has exactly one placement that satisfies all six dots

Controls

• Tap a color swatch below the board, then tap an open cell to place that light there
• Tap a placed light (or its swatch) to pick it back up
