About Tetris
Tetris is the falling-block puzzle that is arguably the most-played video game ever made, and its genius is how little it asks and how much it demands. Seven shapes drop one at a time; you rotate and slide them to pack complete horizontal rows, which then clear and buy you a little more room. The catch is that the pieces never stop coming, and they fall faster the longer you last, so every game is a quiet negotiation between clearing lines now and setting up for the pieces you cannot yet see. Leaving a single deep well for a long piece, keeping your stack low and flat, resisting the urge to panic-place — these are the habits that turn a thirty-second game into a marathon. This version has smooth rotation, a next-piece preview, keyboard and touch controls, and saves your high score. It is instantly familiar, endlessly replayable, and just as good for a quick blast as a long focused session.
How to play
- Move the falling piece left or right with the arrow keys (or the on-screen buttons on mobile).
- Press up to rotate the piece and down to soft-drop it faster; press space to hard-drop it instantly.
- Fill a full horizontal row and it clears, keeping your stack low.
- Clear four rows at once with the I-piece for a "Tetris" and a big bonus. The game ends when the stack reaches the top.
Strategy & tips
- Keep your stack flat and low — a bumpy surface leaves gaps you cannot fill later.
- Leave one column empty on the side and feed it I-pieces to score Tetrises (four-line clears) for maximum points.
- Use the ghost outline and next-piece preview to plan two moves ahead, not just the current piece.
- Rotate against the wall — pieces kick away from the edge, so you can squeeze into tight spots.
- The gravity speeds up every ten lines, so bank clears early while the pace is still slow.
