Here's a masyu puzzle for you. The rules are as follows

  • Draw a single closed loop which does not cross or touch itself.
  • The sections of the loop run horizontally or vertically between the center points of orthogonally adjacent cells.
  • The loop must visit all cells with a white or a black circle but not necessarily all other cells.
  • In a cell with a black circle the loop must turn by 90° and must travel straight through the previous and next cell.
  • In a cell with a white circle the loop must travel straight through and must turn by 90° on the previous or the next cell.

  • None of the pieces may be rotated, and no two pieces may overlap.
  • The thick borders on the pieces must coincide with the perimeter of the grid.



I believe this is the unique solution:
