Nice easy solve. I got the theme before starting to solve, but, something that reveals the nature of the solution can’t be a theme, especially for a layman who would keep looking for a prisoner in the clues and never find one.

• Jack Bross says:

I suspect solving times are going to vary greatly on this one. The break-ins are pretty straightforward, but getting the logic of how everything has to fit together and why is going to take some of us a while to really grok (speaking as someone for whom the penny didn’t fully drop until I’d played around for quite a while). That being said, once I got the logic, it was pretty quick work.

• ghirsch says:

Wow, this was great! I was a little worried about notation at the start (“Am I going to need 10 colors to solve this?”) but fortunately it was manageable.

@Jack: agreed, especially because the logic is so different from normal tapa. This could have been a good one to make a video for, although the Tapa Skyscrapers was probably the better choice between the two.

@Anurag: I disagree, the theme can be about the initial setting of clues, the solution, or even the solving process.

Very helpful to have some experience solving “Black and White” puzzles on this one.
