• Normal Sudoku rules apply.
• A gold cell contains its position within its row, column or box. Position is read from left to right, top to bottom. All possible gold cells are given.
Please note: this puzzle does not require any guessing / bifurcation / case splitting, just good old-fashioned pencil marks.
Solution code: row one

Elegant, simple, and golden; Cells like these I've known as 'friendly cells.'

I did a lot of cluesless sudokus and this one is very aproachable. As is typical for this type, the negative constraint is very strong and helpful. I think a perfect start for cluesless beginners. Thx for sharing.

Definitely one of your easier ones. Took me just over 28 minutes. ◝(ᵔᵕᵔ)◜

Took me a bit to notice the "all possible gold cells are given" part, but I liked it once I found that!

nice puzzle. Don't make the mistake and use the Box number instead of the position in the Box. This mistake made me clueless about Box 5...
