The challenge in front of you

Draw one closed loop whose edges match the count around every numbered cell. An attractive position is not enough unless the goal is met. Follow this game’s rules rather than another version’s.

The order of play

  1. Click an edge to draw, exclude or clear it.
  2. Count the four edges around each cell.
  3. Do not branch or form separate loops.
  4. Check puzzle verifies every clue and loop connectivity.

Keyboard and screen controls

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. A new-round button replaces the current round.

See how the rules apply

A 0 cell has no loop edge around it; a 3 has exactly three. Use the example as a guide rather than a substitute for reading your board. Look for the relevant detail.

One detail worth checking

Several small loops are invalid even if clues match. Take a moment to reassess the position before continuing. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
