The term refers to a specific type of number-placement puzzle presented in a format suitable for printing. It involves multiple standard Sudoku grids that overlap, requiring solvers to apply Sudoku rules across all interconnected grids simultaneously. A common example features five 9×9 Sudoku grids arranged so that the corners of the central grid overlap with the corners of the four surrounding grids.
This puzzle format offers an increased level of complexity and challenge compared to standard Sudoku. The overlapping grids create interdependencies, demanding more advanced solving techniques and greater concentration. The ability to print these puzzles facilitates accessibility and allows enthusiasts to engage with the activity offline, fostering mental acuity and providing a screen-free form of entertainment. Its origins lie in the broader popularity of Sudoku, with puzzle creators adapting the basic principles to create more intricate variations.
