This was like hitting a brick wall! 😀

Did I get five cells right? I’m not even 100% sure… It will be interesting to see if there is a video coming up for this one.

• Jack Bross says:

This was a workout, but fun. It arguably felt more like a “cross the streams” variant than a Tapa variant in terms of how it solved, but then again if Serkan is willing to embrace a puzzle as being a Tapa, I’m in no position to argue.

• Kostucha says:

I love this one. It looked so impossible at the start and yet it has such a unique solving path.

• JuffoWup says:

Loved the logic on this one! Made me want to go back and solve it a second time.

• Michael says:

This took several hours, even though I spotted the break-in *relatively* quick – but then got completely stuck.

After a long time I eventually realized I’d managed to somehow think the break-in relevant clues were on the opposite side of the grid… and then it went a lot easier after starting over with the proper break-in 🙂

• Nikolai says:

Fantastic puzzle. Brutally tough, but still with a really clean logical solving path. Quite impressive that it uses only outside clues, and in a symmetric layout, too. I’m so glad that I gathered the courage to try this one. Thank you!
