Loop Fence

Draw one closed loop along the dots so each number matches how many of its four sides the loop touches. Daily and practice boards.

How to play

  1. Tap the gap between two neighbouring dots to draw a fence segment there. Tap it again to remove it.
  2. Join segments into a single closed loop. The loop may not cross itself or branch, and every dot it touches has exactly two segments.
  3. Each number inside a square says how many of that square's four sides are part of the loop. Squares with no number can have any count.
  4. A number turns green when it is satisfied and red when the loop uses too many of its sides. A dot turns red if three or more segments meet there.

Tips and strategy

  • A zero means none of that square's sides are used, so you never need to touch them.
  • A three next to a zero must wrap around the shared side away from the zero.
  • Look for dots where only two segments are possible, and the loop has to pass through them.
  • Work around the board from the numbers that are easiest to satisfy and let the loop grow from there.

FAQ

Does my loop have to match the hidden one?
No. Any single loop that satisfies every number is accepted, because the game checks the rules and not a stored answer.
Can the loop touch itself at a corner?
No. Every dot on the loop has exactly two segments, so the loop can never cross or touch itself.
Is the daily board the same for everyone?
Yes. It is built from the UTC date and resets at 00:00 UTC.
