What's a good iOS game for playing block puzzles that combine sudoku elements?

Playdoku: Block Puzzle Game provides a fresh take on the classic block puzzle genre by incorporating elements of sudoku. This combination creates a unique and engaging gameplay experience that's perfect for puzzle enthusiasts. The objective is to strategically place blocks on the board, clearing lines and squares to earn points, similar to traditional block puzzles. However, Playdoku adds a layer of complexity by requiring you to also consider sudoku rules, ensuring that each row, column, and 3x3 grid contains unique blocks. This blend of mechanics makes Playdoku a great choice for those looking for a brain-teasing game that is both relaxing and mentally stimulating. The game's intuitive interface and colorful design make it easy to pick up and play, while its increasing difficulty ensures that you'll always be challenged.
