How to Play & Controls

The goal is simple: arrange falling tetrominoes (those seven shapes — I, O, T, S, Z, J, and L) so they form complete horizontal lines. Every full line vanishes, you score points, and the stack gets shorter. Let the blocks pile to the top and it's game over.

On desktop, use the arrow keys to move pieces left and right, the down arrow to soft drop, and the up arrow (or X) to rotate. The spacebar usually triggers a hard drop, slamming the piece straight down. On mobile, tap to rotate and swipe to move or drop — controls vary slightly by version, but they're all intuitive after a round or two.

Key Features

• Increasing speed: The game accelerates as you level up, testing your reflexes.
• Cross-device support: Works on desktops, laptops, tablets, and phones.
• Endless replayability: Every run is different thanks to random piece generation.

Pro Tips & Strategies

1. Keep your stack flat. A level surface gives you options. Avoid tall towers and deep wells unless you're intentionally saving space for a long I-piece.

2. Master the "well" technique. Leave one column open on the side and drop vertical I-pieces into it to clear four lines at once — a Tetris — which scores far more than four separate clears.

3. Plan two pieces ahead. Glance at the next-piece preview and think about where it fits before you commit the current one. Panic-placing is how stacks collapse.
