Thanks for this easier puzzle in your series! A year ago I tried one of the earliest puzzles, but got hopelessly stuck. This one went very smooth. :)

@AlfSmith

No. "A cell is gold" makes a qualification *only* about the cells in gold. It does not make any statement about the other cells.

"if, and only if" implies that gold cells contain position and white cells do not.

As written, this does not have a unique solution.

The solution assumes, but the rules do not say, that all gold cells have been given.

Probably the most approachable gold cell puzzle I’ve done, but still very enjoyable! This is a great puzzle for anyone who has struggled with these constraints.
