On the Subject of Challenged Module Idea

ORDER IN CHAOS. PATTERN IN COLORS. FIND AND ALL BECOME CLEAR.

• This module consists of a 3×3 grid of colored squares. There are four possible colors.
• Press all squares in the correct group to progress the module.
• Pressing a square will cause it to light up white. Make all squares white to disarm the module.
• To begin, press the color group containing the fewest squares.
• After the first group, the correct group to press depends on the number of currently white squares pressed and the group pressed in the previous stage.
• “Group” refers to any of:
  • All squares of a particular color.
  • All non-white squares in the topmost row containing non-white squares.
  • All non-white squares in the leftmost column containing non-white squares.
• Non-white squares may change color after each stage.
• The rule determining the next group is different for every instance of the module, and is initially unknown. You will need to determine its configuration through experimentation and deduction.
• This module never strikes.
