Box and Floor Puzzles

advanced30 min read

The linear-order puzzle family — stacked boxes, building floors, a week's schedule — including how to translate 'above', 'gap of two', 'immediately' and negative clues, run an attribute column, and fix the most constrained variable first.

What you will be able to do

  • Set a fixed numbering for the line and keep one 'top' convention throughout.
  • Translate above/below, gaps, 'immediately', and negative clues into position facts.
  • Fix the most constrained variable first and branch only when forced.
  • Carry a second attribute column and use position-to-attribute clues.
