This bead is at Row 5. Column 3 stopped at Row 1, more than one row above → red (=).
- Column 6 goes down to Row 5, so use Rule 2: look 3 columns back, at Column 3.
- Column 3 stopped at Row 1, more than one row above → red (=).
Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 3 stopped exactly one row above this bead.
