About this puzzle
Sheet #6 starts with 28 givens. Our solver completes it in 56 forced placements, 95% of them singles. Hardest step: Box–line reduction.
Beyond singles, the solution path uses Pointing pair ×1, Box–line reduction ×2.
The givens are spread unevenly: box 1 holds 4 of them, box 4 only 2 (boxes are counted left to right, top to bottom).
Digit 6 is given most often, 5 times; digit 5 only once.
Where to start
A row or column will confine a digit to one box. Remove it from the other cells of that box.
