Medium Cross Sudoku Puzzles
Cross Sudoku is a variant of the classic Sudoku puzzle that involves more complexity and challenge due to its structure. It consists of five standard 9x9 Sudoku grids arranged in such a way that they intersect at one common grid, forming a giant cross-like structure.
The central grid is shared among all the other four, which are placed on each side (top, bottom, left, and right) of it.

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.
