Here's a cool LITS variant that changes a rule in order to use a different set of tetrominos, it's big but juuust not big enough to get the king size tag (4 cells off, amusingly!) Shade one tetromino of cells in each region so that all shaded cells form one orthogonally connected area. Two tetrominoes of the same shape may not touch orthogonally, counting rotations and reflections as the same. There may not exist a run of more than three consecutive shaded cells horizontally or vertically anywhere in the grid Solve on Penpa+
