Gattai is a Japanese word meaning merged or fused. In the world of Sudoku, this term is used for overlapping Sudokus. A number indicates how many 9x9 Sudokus are in the puzzle.
The overlapping regions always contain complete boxes, although it is theoretically possible to overlap any number of cells. For a puzzle maker, partial overlapping boxes are more difficult to create.
Many of these overlapping patterns have been named by their publishers. For each pattern, the most commonly used name is listed first, followed by alternative names.
