■ Normal Sudoku rules apply.
■ Clone Rules (see provided example): There are two sets of 5 Tetris pieces i.e. Tetrominoes. (see provided possible shapes). The pieces in the second set are clones of the ones in the first set (same shape, and digits in the same positions within each piece)..
■ Clues outside the grid: Clues on the top give the number of cells containing Set-1 pieces in that column. Clues on the left give the number of cells containing Set-2 pieces in that row.
■ Adjacency rules: Set-1 pieces may not be orthogonally or diagonally adjacent to each other and may not be orthogonally adjacent to Set-2 pieces (CAN be diagonally adjacent). All cells not belonging to a piece must be orthogonally connected (a cell has to be a part of a continuous region and be orthogonally adjacent to at least another cell).
■ Given Digits: Digits in Circles give the number of surrounding cells belonging to a piece.
Solution code: Row1

kolot: The cell is not counted as it does not belong to the "surrounding" cells, the rule provides no informaion on the cell itself.

“ Digits in Circles give the number of surrounding cells belonging to a piece.” Is the cell itself counted?
