Author/Opus: This is the 45th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: In this variation of Tapa, the wall is in the form of a single non-intersecting loop. Clues inside the grid represent the number of neighboring cells visited by the loop; if there is more than one number in a cell, each number should be represented with a separate loop segment. There is no 2×2 rule of Tapa in this puzzle. This example image should help:

    That was pretty tough for me, although the solving path in retrospect is something I think I could learn to do pretty quickly if I had a deeper feel for the genre. I’d be curious to know if the test solvers were widely varied on this one.

    I ended up having to bifurcate slightly to spot the main break-in.

    Oh my… i couldn’t find the intended path at all. After spotting some deductions in the corners i had to bifurcate like crazy, eventually randomly stumbling onto a solution. Knowing how the solution looked i went back to make some educated guesses to reach contradicions, which i eventually found, but only after a huge huge bifurcation.. don’t know what i missed, too bad that there is no walkthrough for this one.
