    6:51 Thanks for a fun battleship puzzle, Thomas.

    Given Thomas’ dislike of place-all-the-big-ships-first battleships puzzles, I knew to expect something different here. And since three of the four subs were given, I thought he might have set things up to place the fourth sub as an early step.

    Well, I failed to find a breakin along those lines. I’m glad Thomas posted a video walkthrough showing what he actually did intend, because it’s totally different than what I found. Here is what I found for a breakin:

    Nsgre fhogenpgvat gur tvira fhof, jvgu bayl guerr pyhrf nf ynetr nf

    Thomas’ intended breakin would probably have been less effort, so hopefully I can learn from that and start seeing easier starts to some of these puzzles.
