number one

Done it , but no idea what it is.

Certainly not a 5-star difficulty, more like 4 (I used a bit of 2-D logic).
Good puzzle, but I don't know the picture and can't be bothered to look it up!

Thanks! Nice for a first puzzle that it's logical!

No idea what this is meant to be. Even googled it with no luck!

I would agree; enjoyable simple logic but don't understand the image.

Perfect.

Struggled to complete logically.

Thank You.

I made a guess that carried me through to the end: the 5 in c11 starts in R8.
