There are only two 8 digits on the gird, which isn’t enough to place any more 8 digits.
The lower left square is able to place a 9 digit. From now on, this tutorial will not depict the vectors which disqualify cells from receiving a digit. You will have to visualize them yourself.
But the diagram does highlight the 9 digits in neighboring squares which constrain the placement of the 9 digit, circled in blue.
