- Clues per digit: 1 ×3, 2 ×5, 3 ×5, 4 ×1, 5 ×6, 6 ×4, 7 ×5, 8 ×2, 9 ×3

- Warm-up hint: the 1st row has the most clues (5) — a good place to start.
- Watch the 1st column: only 2 of its nine cells are clued, so it holds 7 of the puzzle's open questions.
- Box note: the 4th 3×3 box is the emptiest with just 2 clues — it will demand the most cross-hatching.

Technique focus for this grid
Endgame discipline. When a grid is two-thirds done, stop guessing and count. Rows and columns missing exactly two digits create forced pairs — solving one usually cascades through the rest of the board.
