Daily Sudoku #18 in brief

  • Rated medium: 32 of the 81 cells come pre-filled.
  • The grid as it starts, row by row: 21....... / .3.2...67 / .....1.5. / ..2...514 / 4..8...96 / 9.5..487. / .93..87.. / ...92..3. / 1..5.36...
  • The givens are not spread evenly — the busiest 3x3 box starts with 7, the barest with 2, and that thin box is where the grid will fight you.
  • The digits 4, 6, 7, 8 are the scarcest among the givens.
