Puzzlerium Tour: Slitherlink

Update:

As I resume posting here, albeit with a new dimension to it, I will also have any interested viewers know that the POC (Puzzlerium Optimization Championship) shall be back with another bunch of delightful optimizers in late September. There would be several logical challenges, each on a grid no larger than 12x12 in size. So, if you are looking to put your logical and optimization skills and endurance to test, you want to try this.

Today's puzzle is the first in a series of puzzles that would constitute most of the content to be posted here henceforth. The idea here is to write and post puzzles that involve interesting solution paths and take the viewer through the solution using a video walkthrough that may help understand some of the logical methods.

You will see a link to the solution video tomorrow. Next puzzle on the series will be available soon. 

Rules: Draw a single loop by joining some of the dots. The loop cannot touch or cross itself. Numbers indicate how many of the four surrounding edges are used.

About Slitherlink: This genre was invented by Nikoli Puzzles. The first known Slitherlink puzzle was published in 1989.
