Even More Tetris
(Published yesterday, 14:21 by balpha)
This is my very first attempt at setting a variant Sudoku. Any feedback truly appreciated, even if constructive!
Normal Sudoku rules apply.
Numbers outside the grid indicate the sum of all uninterrupted odd numbers in that row or column, starting from the respective side. For example, if row three were 174652893, then it would say 8 to its left and 12 to its right.
In each of the nine 3x3 boxes, the four even numbers form a Tetris piece.
In every T-shaped piece, the "joint" (the cell that sits next to three other cells) is a 2.
Exactly one of the L/J-shaped pieces is special.
For every non-special L/J piece, the following two hold:
- The "knee" (the corner cell) is a 2, and
- the 6 is one of the two ends.
Neither of those conditions is true for the special L/J piece.
For the avoidance of doubt: There is exactly one special piece. It might be J-shaped or it might be L-shaped.

clarified that there's only one "special" piece, based on comment feedback

The phrasing of the rules is a bit vague when it comes to the special pieces:
Are there 2 special pieces, one L and one J, or is there exactly one special piece among all L's and J's combined?
