It’s a simple yet challenging puzzle you won’t be able to put down.\n\nMatch blocks to complete lines and squares to remove them. Keep the board clean, and beat your high score.\n\nHow to play:\n\n- Drop the blocks on the 9x9 grid.\n- Fill up lines and squares to keep the board clean.\n- Complete Daily Challenges and get unique trophies.\n- Join Seasonal Events and get unique animated postcards.\n- Compete against other players in Tournaments, beat your high score, and climb the leaderboard.\n- Destroy several elements at once to make a Combo.\n- Make several successful moves in a row to get a Streak.\n\nHow to become a Blockudoku® master?\n\n• There is no time limit, so no need to rush. Think one step ahead when faced with a difficult move. It might be your last one.\n• Try to place blocks on the board to destroy lines or 3x3 squares with every move to keep the board from filling up.\n• Find your zen by balancing between destroying figures as quickly as possible and getting as many combos and streaks as you can to score higher.\n• Score more points by making streaks. The emptier the board, the better for you!\n• It's always risky to wait for a good block – you may quickly run out of moves.
