The goal of Sudoku is to fill a 9x9 grid so that each row, column, and 3x3 internal block contains all digits from 1 to 9. It’s a game of pure logic, not math-meaning you don’t need to be a human calculator to win, just a sharp observer.
Start by "Cross-Hatching" look at a 3x3 block and scan the surrounding rows and columns for a specific number to eliminate empty cells. If you’re stuck on Hard or Expert levels, look for "Naked Pairs" (two cells in a block that can only contain the same two numbers) to clear out the rest of the candidates.
Focus on Frequency: Start with the numbers that are already most common on the grid to find easy placements.
Work in Sections: Completing one 3x3 block often provides the "missing link" for the adjacent rows and columns.
Don't Rush: Speed comes with practice. Focus on accuracy first, and your "solve time" will naturally decrease over time.
