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 — 41 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
- R2C2 = 6 · Hidden SingleIn the top-left 3×3 box, 6 fits in only one cell. Looking at the other empty cells:- Because column 1 already has a 6, R1C1 cannot hold 6.- Because column 3 already has a 6, R1C3 cannot hold 6.- Because row 3 already has a 6, R3C2 cannot hold 6.So 6 must go in R2C2.
- R3C6 = 4 · Hidden SingleIn the top-centre 3×3 box, 4 fits in only one cell. Looking at the other empty cells:- Because row 1 already has a 4, R1C4 and R1C5 cannot hold 4.- Because row 2 already has a 4, R2C6 cannot hold 4.So 4 must go in R3C6.
- R2C6 = 7 · Hidden SingleIn the top-centre 3×3 box, 7 fits in only one cell. Looking at the other empty cells:- Because column 4 already has a 7, R1C4 cannot hold 7.- Because column 5 already has a 7, R1C5 cannot hold 7.So 7 must go in R2C6.
- R2C7 = 1 · Naked SingleLooking at R2C7:- Row 2 already has 2, 3, 4, 5, 6, 7, 8 and 9 → ruled out.So this cell can only be 1.
- R1C4 = 1 · Hidden SingleIn the top-centre 3×3 box, 1 fits in only one cell. Looking at the other empty cells:- Because column 5 already has a 1, R1C5 cannot hold 1.So 1 must go in R1C4.
- R1C5 = 3 · Naked SingleLooking at R1C5:- Row 1 already has 1, 4, 5, 8 and 9 → ruled out.- Column 5 already has 6 and 7 → ruled out.- The top-centre 3×3 box already has 2 → ruled out.So this cell can only be 3.
- R3C2 = 3 · Hidden SingleIn the top-left 3×3 box, 3 fits in only one cell. Looking at the other empty cells:- Because row 1 already has a 3, R1C1 and R1C3 cannot hold 3.So 3 must go in R3C2.
