About Sheep and Wolves
Draw a single closed fence across a moonlit pasture. Keep every sheep inside, every wolf outside, and match the numbers printed in the field.

How to play
- Goal
- Draw one fence that keeps every sheep inside and every wolf outside.
- How it ends
- One closed, non-crossing loop must match every numbered cell.
- Record
- First unaided solve · fastest time.
- Choose Line and tap or drag between neighbouring posts to place fence rails.
- Make one closed loop. It cannot branch, cross itself, touch itself at a post or split into separate loops.
- Every sheep must be inside the fence; every wolf must be outside. The fence may run along the outer edge of the field.
- A number gives the exact count of rails around that cell, from zero to four.
- Cross marks a side you think is unused. Crosses are optional reminders, and Erase removes a mark.
- Finish the loop and satisfy every clue to complete the puzzle.

- Separate neighbours A sheep and a wolf in adjacent cells need a rail between them.
- Follow the posts Every used post must eventually connect exactly two rails.

Questions
Must I mark every unused side?
No. Cross notes are optional; only the fence determines completion.
May the fence use the edge of the field?
Yes. Outer edges are legal fence positions.
Can there be several loops?
No. All rails must form one closed loop.
