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!
