5 by 5 puzzle 1 is ready. Choose an edge to begin the loop.

Standard rules & controls
  • Each clue tells how many of its four sides belong to the loop.
  • Draw exactly one closed loop. Every dot has zero or two line edges, so the loop cannot branch, cross, or stop.
  • Edges cycle blank, line, and cross. Crosses are notes for edges you have ruled out.
  • The puzzle is complete when all clues are satisfied by one non-branching loop; unused edges do not need crosses.

Hints reveal one edge from the independently verified unique solution. That assistance remains recorded after undo.
