I feel like I’m missing a constraint – but I’ll probably just feel embarrassed when I come back to this later and quickly realize why there aren’t a dozen or so possible answers.
If you have solved classic LITS before, the only possible constraint you could miss is that the clue points to the first encountered tetromino, and not any tetromino in that row/column.
Well, the thing that may be forgotten due to the grid design is that there’s only one tetromino per region, so you’re only placing four tetrominoes.
Nope, way stupider than that. For reasons I can’t explain (but I blame the nice roomy regions), I was using a 5-cell T.
If it helps you feel any better, I was doing the same thing at first!
