Yajilin Fences
Yajilin on igrasu.ru is a loop-and-shade puzzle: draw one closed loop through cell centers, paint every cell the loop skips black — and no two black cells may touch.

The rules in brief
The loop never crosses or branches. A numbered arrow clue tells exactly how many black cells stand in that direction — and black cells may not touch each other, not even at corners. Every cell ends up either on the loop or black.
Where to start
Start on small boards: the logic is fully visible there. 'Hint' fills one correct cell, 'New' deals a fresh board.
