I just started playing this game with regularity recently. One strategy I like to use is trying to get all 9 of a number out of the way. So I will figure out where to put 7-9 of the 3s or 5s or 6s to get them out of the way.

However after I do that I notice there are always a few numbers that are barely on the board. Maybe there are eight 5s, but there are only two 1s on the board. Which means for each empty space, I have no idea where the 1 goes. I end up creating a bunch of empty spaces and having three or four numbers that are barely on the board, so now I don’t know where those numbers go.

I find this strategy helps me place numbers in the beginning of the game, but makes it harder by the middle of the game than when I do not use this strategy.

Is there a name for this strategy?
