Step 1

Then I extended with the chains of Ls:

Step 2

Filled in a couple of forced things:

Step 3

And the rest was easy (see top)

  • $\begingroup$ The step where you extend the chains of L's pre-supposed that the snake wouldn't leave via an L at the edge. On the other hand, any place there's a straight line, knowing almost anything about any of its neighbors will reveal whether it must be horizontal or vertical. $\endgroup$
