Place a digit from 1-9 (or 1-6 for the example puzzle) in each cell so that digits do not repeat in any row, column, or outlined region.
LITS...: shade some cells in the grid so that each region contains a single group of four orthogonally connected shaded cells, which form a tetromino (L, I, T, or S). Wherever two tetrominoes share a border, they must be different from each other. Rotations and reflections are considered to be the same. All shaded cells form a single orthogonally connected group. No 2x2 region is entirely shaded.
...doku: Also, each region is marked with a clue. The clue gives the sum of the digits in that region's tetromino.

That will teach me to not use setter meta. Just shows the range of what you can do. Fantastic puzzle!

Stupendous and also rather carefully set puzzle! I adore how the tetrominoes were determined through different ways, and the second half was somewhat wonderful to unfold (which must've taken a long while to set) x)
