Some basis Sudoku Solving techniques include:

• A first step in solving Sudoku Puzzles is to look for cells that can only contain one particular number. Look for the last remaining empty cells in 3x3 boxes, rows, or columns.
• The next steps is to look for rows or columns, between the bold lines that separate the boxes, that already contain two of the same numbers. You can now try to place that same number in the remaining row or column.
• Use pencil marks (smaller numbers) or candidates for a cell. Enter all candidates for a row, column or 3x3 box and find cells that only have one candidate.
