Basic Rules

Horizontal: Each row of 9 cells must contain all the numbers from 1 to 9, without duplicates and in any order.
Vertical Column: Similarly, each column of 9 cells must also contain all the numbers from 1 to 9 without duplicates.
3x3 Block: There can only be one number from 1 to 9 in each 3x3 block (9 blocks in a 9x9 grid).

These rules are simple but require high concentration and sharp logical thinking to complete the puzzle, especially at the Expert and Guru levels.

Tips for Effective Play

Start with the cell with the fewest options: Look for rows, columns, or 3x3 blocks that already have many numbers filled in. This arrangement makes it easy to identify the missing number.

Use the elimination method: eliminate numbers that cannot appear in the cell based on the numbers already in the row, column, and 3x3 block.

Note down potential numbers: Use the notes feature to list the numbers that can fill in the blank cell, helping you systematize your thinking and avoid mistakes.

Apply advanced tactics: On difficult levels, try techniques like X-Wing or Swordfish to pinpoint the exact location of the numbers.
