Last free cell is an easy Sudoku solving technique for beginners. It's pretty simple and based on the basic Sudoku rule that each 3×3 block, column or row on the grid should contain numbers from 1 to 9 and each number can be used only once within that 3×3 block, column or row.

4. Sudoku Notes

Taking Notes makes the process of solving Sudoku faster and easier. Moreover, without Notes, it is quite difficult to apply advanced Sudoku techniques in practice.
5. Obvious singles
34,381+ views
This strategy is based on the correct placement of Notes. Sometimes it is called Naked Singles. The idea is that in a specific cell only one digit from the Notes is possible. It's a rather simple Sudoku technique that is suitable for beginners.
6. Obvious pairs
44,149+ views
Like the "Obvious Singles" technique, "Obvious pairs" is based on the correct placement of Notes. The object is to find 2 cells with the same pairs of Notes within a 3x3 block.
7. Obvious triples
51,267+ views
This Sudoku solving technique is built upon the previous one - "Obvious pairs". You can watch a video about it on our Sudoku.com channel. The "Obvious triples" rule is based on three numbers instead of two.
8. Hidden singles
44,478+ views
The idea behind "Hidden singles" is that a Note is the only one of its kind in an entire row, column, or 3x3 block. However, this technique requires player focus because it can be quite hard to spot the single Notes.
9. Hidden pairs
84,947+ views
The "Hidden pairs" technique works the same way as "Hidden singles". The only thing that changes is the number of cells and Notes. If you can find two cells within a row, column, or 3x3 block where two Notes do not appear elsewhere, these two Notes must be placed in the two cells. All other Notes can be eliminated from these two cells.
10. Hidden triples
111,443+ views
"Hidden triples" applies when three cells in a row, column, or 3x3 block contain the same three Notes. These three cells also contain other candidates, which may be removed from them.
11. Pointing pairs
71,410+ views
"Pointing pairs" is an intermediate Sudoku technique. It applies when a Note is present twice in a block and this Note also belongs to the same row or column. This means that the Note must be the solution for one of the two cells in the block and can be eliminated from any other cells in the row or column.
12. Pointing triples
54,318+ views
"Pointing triples" applies if a Note is present in only three cells of a 3x3 block and also belongs to the same row or column. This means that the Note must be a solution for one of these three cells in the block, can't be a solution for any other cell in the row or column and can therefore be eliminated from them.
13. Х-wing
156,497+ views
"Х-wing" is an advanced Sudoku technique, which is based on two parallel rows or columns. You can ignore the 3x3 blocks as they aren't involved in this strategy. This is a rather difficult Sudoku strategy. But knowing tricks such as Х-wing will help you solve Sudoku much faster.
14. Y-wing (XY Wing)
473,094+ views
"Y-Wing" is an advanced strategy for Sudoku experts. It often comes up in the difficult puzzles and it may take you some time and practice to figure it out. The "Y-Wing" technique is similar to "X-Wing", but is based on three corners instead of four.
15. Swordfish
220,236+ views
The "Swordfish" technique is an advanced Sudoku strategy. It's usually applied in harder levels of Sudoku puzzles to eliminate candidates. "Swordfish" is similar to X-wing but uses three sets of cells instead of two. So, it's a little more complicated than X-wing , but the logic is the same.
