Some puzzles seem to be simple at first, but turn out to be a tremendous challenge when you try them. Blockudoku is one of them. Your task is to build lines and squares by matching blocks to make them disappear from the screen. The cleaner the board the higher the score! The blocks fall on a 9×9 grid where you have to place them keeping your goal in mind. Putting together several elements simultaneously will strike a spectacular combo! You can compete with hundreds of other players and see how many points you can get.
