Notes on this puzzle
Sudoku #5102 is an easy grid with 41 givens, which leaves 40 cells waiting for a digit. Played purely by logic, it takes 40 forced steps from the first placement to the last.
Nothing beyond hidden single is needed anywhere, so the whole grid is a scanning exercise.
Among the givens, 2 is the most common digit (7 times) and 7 the rarest (2). The emptiest box is the top-middle one, with 3 givens; the top-right box is the most crowded, with 6.
Where to beginLook at row 3, column 4 first: a hidden single is available there from the very start. Scan digit by digit; notes are hardly needed here.
