About this puzzle
Sheet #1 starts with 38 givens. Our solver completes it in 43 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 3 holds 7 of them, box 1 only 2 (boxes are counted left to right, top to bottom).
Digit 1 is given most often, 6 times; digit 8 only once.
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.
