Previously I referred to these puzzles as “Super Samurai Sudoku“. Well, I’m going to start calling them what others call them and that is Sumo Sudoku.
Whatever you call them, there are 13 overlapping sudoku grids in each! Huge! And they overlap Samurai Sudoku style, so it’s like having 4 Sudoku Samurai puzzles on top of each other.
Finally… this puzzle that I’m posting now is a consecutive sudoku variant. 🙂 Vertical and horizontal bars show cells which must contain consecutive numbers. Other adjacent cells must be non-consecutive.
