Place exactly one tetromino in each area such that all tetrominoes are connected. There is no 2x2-square completely occupied by tetrominoes. Identical tetrominoes must not share an edge (rotated or mirrored tetrominoes are identical).
Solution code: Row 6 and column 6: The letter (L, I, T or S) of each tetromino in this row/column. Only one letter for each tetromino even if several cells in this row/column belong to the same tetromino.
