Solve it in the app to get on the board

Step-by-step solution

Every cell below is filled by the same hint engine the app uses, in the order it can be deduced — 47 steps using 2 techniques.

Techniques used

  • Hidden Single — inside one row, column or box this digit fits in only one cell, so it must go there
  • Naked Single — every other digit is already used in this cell's row, column or box, so only one candidate is left
  1. R1C3 = 5 · Hidden SingleIn the top-left 3×3 box, 5 fits in only one cell. Looking at the other empty cells:- Because column 2 already has a 5, R1C2 and R3C2 cannot hold 5.- Because column 1 already has a 5, R3C1 cannot hold 5.So 5 must go in R1C3.
  2. R1C6 = 7 · Hidden SingleIn the top-centre 3×3 box, 7 fits in only one cell. Looking at the other empty cells:- Because row 2 already has a 7, R2C5 cannot hold 7.- Because row 3 already has a 7, R3C4, R3C5 and R3C6 cannot hold 7.So 7 must go in R1C6.
  3. R1C7 = 1 · Hidden SingleIn the top-right 3×3 box, 1 fits in only one cell. Looking at the other empty cells:- Because column 8 already has a 1, R1C8 and R3C8 cannot hold 1.- Because row 2 already has a 1, R2C7 and R2C9 cannot hold 1.So 1 must go in R1C7.
