Sudoku solving strategy with effective tricks
Solving Sudoku is not only based on luck but mainly on logic and strategy. Your task is to fill all the blank cells in the 9x9 board so that each row, each column, and each 3x3 area contains all the numbers from 1 to 9 without repeating. Use reasoning and analysis to find the right number and quickly become a master of filling in winning numbers. This version is especially similar to Sudoku, where you also need to reason carefully to find the right number
Start with easily recognizable numbers
- Observe the rows, columns, and 3x3 areas to find cells with only one possible number left.
- Fill in these numbers first to reduce the blank cells, making it easier to deduce further.
- For each blank cell, identify all the numbers from 1 to 9.
- Eliminate the numbers that have appeared in the row, column, and 3x3 area.
- The remaining number is the number you can fill in that cell.
Find hidden pairs or triples
- Hidden Pairs: When two cells in the same row, column or region can only contain the same 2 numbers, you can eliminate those 2 numbers from the other cells in that row, column or region.
- Hidden Triples: Similarly, when three cells contain the same 3 possible numbers, you can use this technique to eliminate the possibility from the other cells.
