Clueless Explosion Sudoku

Clueless Explosion (Clueless-1) is a combination of 10 Sudoku grids. The central cells of every block combine to form the tenth puzzle.

Rules: 10 regular 9×9 Sudoku grids are interwoven in such a way that no single grid can be solved by itself, but all 10 grids together have a unique solution. The 10th grid is formed by 9×9 coloured centre cells.
In each cell of the 9×9 grid, enter a number from the range 1–9. Each number must appear exactly once in each row, column, and block.
