Start with the easy level and work your way up to the harder ones. This will help you build your confidence and skills.
Look for the obvious numbers first. For example, if a row, column, or sub-grid has only one empty cell, you can easily fill it with the missing number.
Use the process of elimination to rule out impossible numbers. For example, if a row, column, or sub-grid has two empty cells, and one of them can only be 1 or 2, then the other one cannot be 1 or 2.
Look for patterns and groups of numbers that can help you solve the puzzle. For example, if a sub-grid has three empty cells in a row, and they can only be 3, 4, or 5, then those numbers cannot appear in the same row or column in the other sub-grids.
Use logic and deduction to find hidden numbers. For example, if a sub-grid has four empty cells, and three of them can only be 6, 7, or 8, then the fourth one must be 9.

The techniques and strategies to solve sudoku puzzles
Sudoku puzzles can be solved using various techniques and strategies, depending on the difficulty level and the game mode. Some of the most common and useful techniques are:
Naked single: This is when a cell has only one possible candidate. You can fill it with that number and eliminate it from the other cells in the same row, column, and sub-grid.
Hidden single: This is when a number can only appear in one cell in a row, column, or sub-grid, even though there are other candidates in that cell. You can fill it with that number and eliminate it from the other cells in the same row, column, and sub-grid.
Naked pair: This is when two cells in a row, column, or sub-grid have the same two candidates. You can eliminate those two numbers from the other cells in the same row, column, and sub-grid.
Hidden pair: This is when two numbers can only appear in two cells in a row, column, or sub-grid, even though there are other candidates in those cells. You can eliminate the other candidates from those two cells and treat them as a naked pair.
Naked triple: This is when three cells in a row, column, or sub-grid have the same three candidates. You can eliminate those three numbers from the other cells in the same row, column, and sub-grid.
Hidden triple: This is when three numbers can only appear in three cells in a row, column, or sub-grid, even though there are other candidates in those cells. You can eliminate the other candidates from those three cells and treat them as a naked triple.
X-wing: This is when two rows (or columns) have two cells each that can contain the same number, and those cells form a rectangle. You can eliminate that number from the other cells in the same columns (or rows) as the corners of the rectangle.
Swordfish: This is an extension of the X-wing technique, where three rows (or columns) have three cells each that can contain the same number, and those cells form a shape like a fish. You can eliminate that number from the other cells in the same columns (or rows) as the corners of the fish.
Coloring: This is a technique that uses colors to mark the candidates of a certain number. You can use two colors to alternate between the candidates of that number in different rows, columns, and sub-grids. If you find a contradiction or a loop with the same color, you can eliminate that color from the puzzle.
Guessing: This is a technique that involves making an assumption and following its consequences. If you find a contradiction or an impossibility, you can discard that assumption and try another one. If you find a solution or a confirmation, you can keep that assumption and continue solving. This technique should be used as a last resort, as it can be time-consuming and error-prone.
