A small practice goal

After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.

The goal to keep in mind

From the start of a round

  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.

Input guidance

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. 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. Check the stated objective.

A common point of confusion

Several small loops are invalid even if clues match. Take a moment to reassess the position before continuing. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
