LEV    PUZ  

Yajilin, also known as Arrow Ring or Straight and Arrow, is a logical loop puzzle published by Nikoli.

  • The goal is to make some cells black and draw one continuous non-intersecting loop that connects the other cells.
  • The loop must not cross cells that contain an arrow or that are black.

Black cells :

Some cell must be made BLACK and do NOT belong to the loop.

  • A cell with a number and an arrow indicates how many black cell are in that row or column in the direction of the arrow.
  • Black cells can only touch each other diagonally.
  • There may be black cells without arrows pointing to them.

Dot box:

The first option you can choose is a cell with a dot. This serves as an aid to indicate that this box certainly belongs to the loop, but that you do not yet know which loop shape you should choose. It is therefore a provisional choice.
