# Clueless Explosion

This page offers a weekly Clueless Explosion puzzle. There are 9 Sudoku grids which must be solved according to the standard rules. The cell in the center of each box has a blue color. Together, these cells form a 10th sudoku, in the same formation you see them on your screen. Each of the 9 Sudokus adds a 3x3 box to this central Sudoku. Solving these puzzles requires a lot more patience than usual. None of these 9 puzzles can be solved independently, so you need to use the interaction with the central Sudoku. To check your results, go to the list of submissions.

Keep in mind that each of the 9 Sudokus is also a Center-Dot Sudoku, because the 9 blue cells must also contain digits 1 through 9. If you need some assistence in handling this puzzle format, you can download the Clueless Helper, a program that can open these puzzles directly from this website.
