- Analyze the overlapping regions between the five interconnected 9x9 grids to identify cells that are constrained by multiple grids.
- Use standard Sudoku rules: each row, column, and 3x3 box within each grid must contain digits 1–9 without repetition.
- Start with cells that have the fewest possible candidates based on existing numbers in their row, column, and box across all overlapping grids.
- Fill in cells where only one digit is possible due to constraints from adjacent grids.
- Propagate solved values through overlapping regions to reduce possibilities in neighboring grids.
- Continue this process iteratively, resolving contradictions and filling in forced moves until all cells are filled.
- Verify that every row, column, and 3x3 box in all five grids contains digits 1–9 exactly once.
