Normal sudoku rules apply.
- Cells separated by a white dot must contain consecutive digits.
- Mark nine tetrominoes in the grid such that every 3x3 box contains exactly one tetromino with no overlap between 3x3 boxes. No two tetrominoes are orthogonally adjacent. Every row and column contains exactly four marked cells.
- Digits in a tetromino indicate how many times that digit appears in a tetromino.
- Every tetromino must sum to the same number.
- Digits within a cage must be part of a tetromino and do not count towards the tetromino's sum.

Incredible to get to the stage of only having sudoku left to do, and then a quality sudoku after that as well.

Are all tetrominos of the same style ? For instance L-Type ?
