How do you play the game Woodoku?

Woodoku is a puzzle game that combines elements of Sudoku and wooden block puzzles. The player is presented with a 9x9 grid reminiscent of a Sudoku board, and the objective is to place available wooden blocks onto the grid to clear lines both vertically and horizontally. As in the classic block game Tetris, these pieces come in various shapes and cannot be rotated. The blocks must be placed strategically because once a line is filled completely with wood pieces, it clears from the board, creating space for new pieces. Points are scored when lines are cleared or when special squares on the board are filled. If he can no longer place any of the given blocks into the grid due to lack of space, the game ends. Therefore, careful planning and foresight are crucial to achieving high scores and advancing through Woodoku's increasingly challenging levels.
