LEV    PUZ  

Masyu, also known as ShiroshinjuKuroshinju or White pearls and black pearls, is a logic puzzle. It is played on a rectangular grid of cells. Some cells contain white or black circles. The goal is to draw a continuous non-intersecting loop that will correctly pass through all cells with circles.

The two types of circles have different requirements for how the loop should go through them:

  • White circles must be traveled straight through and the loop must turn in the previous and/or next cell in its path.
  • Black circles must be turned upon and the loop must travel straight through the next and previous cell in its path.
