Tetromino Korobeiniki Sudoku
(Published on 20. July 2020, 16:45 by logopolys)
Non-overlapping tetrominoes must be drawn into the grid with all cells in the grid being covered by a tetromino. Tetrominoes may not orthogonally touch other tetrominoes of the same shape. This includes rotations but not reflections (ie, the S-tetromino is not the same as the Z-tetromino). Some cells are marked with a letter indicating what shape tetromino that cell must be part of. Some walls are drawn on the grid. These walls must divide two different tetrominoes.
Each tetromino must contain the numbers 1 through 4 exactly once. Each row and column of the grid must contain the numbers 1 through 4 exactly twice. All cells marked with a circle contain the same number. All cells marked with a diamond contain the same number.
