Tetro Chain Y

Place connected tetrominoes and satisfy the directional number clues.
Controls
Place tetrominoes of four orthogonally connected cells. Tetrominoes may not touch orthogonally and may not cover number cells. A number with an arrow counts the tetromino cells in that direction. Two tetrominoes that touch at a corner must have different shapes, and all tetrominoes must form one diagonally connected chain. Tap cells to shade or clear them, then use Clear and the answer button.
