Tetris

What is Tetris?

Tetris is the classic puzzle game where you arrange falling tetrominoes — seven distinct geometric shapes — to clear horizontal lines. Each line you complete disappears and rewards points; let the stack reach the top of the playing field and the game ends. It's easy to learn, endlessly replayable, and tests reflexes alongside spatial planning.

Modern Features

• Hard drop: Slam the current piece straight to the bottom with Space — and earn 2 bonus points per cell dropped.
• Soft drop scoring: Holding Down or S earns 1 point per cell as you accelerate the piece downward.
• Ghost piece: A faint outline shows exactly where the falling piece will land — no more guessing.
• Hold: Press C or Shift to stash the current piece and swap it back later. One swap per turn.
• Next preview: See the upcoming piece so you can plan two moves ahead.
• Wall kicks: Rotations near walls automatically nudge the piece into a valid spot when possible.

How to Play

1. Start the game with the Start button.
2. Move pieces with arrow keys or WASD.
3. Rotate with Up arrow or W. The game tries small wall kicks if the rotation would clip.
4. Soft drop with Down or S — adds 1 point per cell.
5. Hard drop with Space — instant lock, 2 points per cell.
6. Hold a piece with C or Shift — useful when you need to save an I-piece for a Tetris.
7. Clear lines by filling complete rows. Four at once = a Tetris (1200 × level points).

Tips for High Scores

Use the ghost. Don't guess where the piece will land — line up exactly where you want it before letting go.

Save your I-piece. Hold (C / Shift) the long I-piece until you have a 4-line well ready. A single Tetris is worth 30× more than four singles.

Hard drop only when committed. Once you press Space the piece locks instantly — no rotating after.

Plan two moves ahead. The Next panel tells you what's coming. Adjust placement of the current piece accordingly.

Build flat. Tall, jagged stacks limit your options; aim for a smooth surface broken only by your Tetris well.
