About this puzzle
Sheet #9 starts with 40 givens. Our solver completes it in 41 forced placements, 100% of them singles. Hardest step: Hidden single.
Singles carry this grid all the way — no pairs, no patterns.
The givens are spread unevenly: box 1 holds 5 of them, box 3 only 3 (boxes are counted left to right, top to bottom).
Digit 1 is given most often, 7 times; digit 3 only 2 times.
Where to start
Scan one digit at a time across all nine boxes. Every step of this sheet is a digit with only one possible cell in some row, column or box.
