The squares of the six polyominoes depicted below are either filled or empty. What logic was used to determine whether a square filled?

(In reply to re(2): Too Hard Basket??? by Vernon Lewis)

As I read once: "Donīt follow me, Iīm lost too".

But why the "lightbulb", which means "full solution"?

I still think that the way is joining the pieces to find a pattern of bits (as you said). Only when they were joined properly, a well-known sequence - primes, Fib, whatever (assuming marked cells as "1" and "0" otherwise) will appear.

Of course, I can be driving in the opposite direction. I asked a question to Brian, but he didnīt answer yet.
