About this puzzle
Sheet #2 starts with 26 givens. Our solver completes it in 56 forced placements, 98% of them singles. Hardest step: Pointing pair.
Beyond singles, the solution path uses Pointing pair ×1.
The givens are spread unevenly: box 3 holds 4 of them, box 1 only 2 (boxes are counted left to right, top to bottom).
Digit 3 is given most often, 5 times; digit 8 only once.
Where to start
Somewhere a digit is confined to one row or column inside a box. Use that to clear the digit from the rest of the line.
