Continue the Line

One line reaches a dot and only one exit remains, so the line must continue through that exit.

How it works

  1. 1One line already reaches the middle dot. Two of the other directions are crossed out.
  2. 2A loop cannot stop at a dot: a touched dot needs exactly two lines.
  3. 3Only the bottom edge can carry the line away, so draw it.
  • Edge on the loop
  • Edge the technique adds
  • Edge ruled out
  • Cells that establish the pattern
Next in the ladder No Single Edge →

An untouched dot with only one possible edge cannot use it, because that would leave exactly one line at the dot.
