Easy Cross Sudoku Puzzles

About Cross Sudoku

Cross Sudoku is a unique and more challenging version of the traditional Sudoku puzzle. Instead of working on just one 9x9 grid, this variation uses five 9x9 grids that are arranged in a cross-like pattern. There is one central grid at the middle of the cross, and it connects to four outer grids; one on each side (top, bottom, left, and right).

Basic Rules (Same as Classic Sudoku):

• Grid Structure: The puzzle comprises five 9x9 grids, with one central grid and four additional grids arranged around it, creating a cross formation.
• Number Placement: Each grid must be filled with the numbers 1 through 9.
• No Repetition: Numbers must not repeat within any row, column, or 3x3 sub-grid of each 9x9 grid.

Extra Rule for Cross Sudoku:

• Intersecting Grids: The central grid is shared by all the other grids and must adhere to the rules of each connected grid simultaneously.
• Independence: While the grids are interconnected, the left, right, top, and bottom grids function independently from one another, except for their interaction with the shared central grid.

Solving Tips:

• Start with the Central Grid: Begin by solving the central grid, as it is shared by all other grids and provides crucial clues for the surrounding grids.
• Single Possibility: Identify squares where only one number can fit, based on Sudoku rules.
• Elimination: Eliminate impossible numbers from a square by considering its row, column, and 3x3 sub-grid.
• Look for Grid Independence: Focus on solving the rows, columns, and squares in the outer grids that do not intersect with the central grid, as these can be tackled like a standard Sudoku puzzle.
• Use Pencil Marks: Use pencil marks to note possible numbers in each square and update them as you progress to keep track of potential options.
