LEV PUZ

Grand Tour Puzzles, also known as RoundTrip puzzles, have a grid of points that all need to be connected by a single loop. It is very simular to a Slitherlink Puzzle. To start the puzzle, a few of the points are already connected to insure a unique solution. Use logical deductions to solve it.

The puzzle is correct when you have placed:

  • All the complete black lines that are part of the loop.
  • All the short black lines that are not part of the loop.

Make sure all the lines are black!
