What are the main difficulties you found in solving it? (Mark as many as they apply)
First time I solve a Sudoku
I found it harder than usual.
I can't follow the logic, I am just trying to guess the numbers
Too many possibilities to consider, I can only handle 1 or 2 at a time.
I have trouble with multiple step tasks.
I cannot concentrate more than a few minutes on a problem.
