How do you rotate pieces in this online Tetris game?

On desktop, you can rotate blocks by pressing the Up Arrow or W key. On mobile and tablet devices, simply tap anywhere on the game board canvas or use the virtual Rotate (🔄) button below the board.

What is the difference between Classic Marathon and Progressive Puzzle mode?

Classic Marathon uses the standard 7 tetromino shapes with traditional rotation rules. Progressive Puzzle mode starts with simple blocks (1x1, 1x2) on Level 1, and introduces more complex and irregular custom shapes (up to 19 total variations) as you clear lines and level up.

How does the Ghost Piece and Hold Queue help in gameplay?

The Ghost Piece shows a faint outline projection at the bottom of the grid, showing exactly where your active block will land. The Hold Queue allows you to temporarily stash a piece (press Shift or C on desktop, or swipe up on mobile) to swap and deploy it later.

What are Super Rotation System (SRS) and Wall Kicks?

Super Rotation System (SRS) is a standard mechanism that checks offset translations (wall kicks) when you rotate a block next to grid borders or other settled blocks. This prevents blocks from getting stuck and allows you to slide them into tight spots.

How is my high score saved?

Your high scores for both game modes are automatically saved locally to your web browser's localStorage. Refreshing or closing the page will not erase your personal best records.
