Sudoku Hints

The Sudoku Instructions Program can give you hints, tips and tricks during solving of any sudoku puzzle. Thereby it can help improve your sudoku skills.

Consider this sudoku puzzle:

If you cannot find a square in which there can be just one single digit - ‘a single candidate’, then you can ask the program for a hint or tip.

Sudoku hint 1

If you click ‘Hint 1’ you will get this message:

Sudoku hint 2

However, if you need more help just click ‘Hint 2’. Then you will get this message:

Find single candidate

If you cannot find a single candidate, you may get the necessary help by asking the program using menu item ‘Solve’ and ‘Find Single Candidate’ as shown here:

If you do that, you will get this message:

Here you get the information you need. Now you will also be able to see why digit 2 must be in square C4.

(In column C digit 2 cannot be inside box J or box P, where there already is a 2. In row 6 there is also a 2. Therefore in column C digit 2 can only be in square C4.)

So you place 2 in that square:

If you proceed in the same way, you will arrive at this final solution of the sudoku puzzle:
