Oh, I see now. Thanks!
From the wording, I was expecting each golden post in the column to be n*n, so 5 distinct golden posts would total 125, which would be interesting but maybe unbalancing, especially in the larger game.
It might not be too much of a spoiler to list the values up to 10, wording it like the description of the normal posts, since by the time a player gets a golden post, they've probably seen enough to guess at the larger game.
