Edit : Swaroop Guggilam has showed me that this one has an easier break-in than the one I intended. So, just in case you didn’t enjoy the one I intended, I’ve changed a few clues and added the difficult version.
When I posted my first Graffiti Snake, it was as a practice puzzle for the LMI Puzzle Marathon. While it was nowhere near the absolute beauty contributed by Serkan to the test, it was still quite a popular day for my blog apparently. Now whether thats because I’m actually good at creating these, or because it was practice, or both is something I wanna judge for myself, so I’ve waited for the test to get over and made another one, slightly smaller in size. I’ve also put in a different kind of break-in to the last one.
Btw, Puzzle Marathon is now over, and the results can be seen here.
Anyway, Rules for Graffiti Snake :
Paint some cells black to form a wall. The numbers outside the grid indicate the number of blackened cells in the corresponding direction, in order, as in a Paint by Number puzzle. If there is more than one blackened block in a row or column there has to be a white cell between the blocks. Additionally, a snake must pass through all the remaining white cells, moving horizontally and vertically and not touching itself, not even diagonally. The head and tail of the snake are given as the grey circles.
Rated : Hard, simply because a few people were clueless on how to start the last one for quite a while.
