Tetris

Falling blocks, a narrow well, and your brain thinking four moves ahead. Tetris is the most famous puzzle game ever made — learnable in a minute, never truly mastered. Tap Play above.

The Game That Never Gets Old

Seven block shapes — the tetrominoes — fall one by one into a well. Rotate and slide them into place, and every complete horizontal row vanishes for points. Clear four rows with a single long bar — a “Tetris” — for the biggest reward of all. The catch: as your score climbs, pieces fall faster until every decision must be instant. Part puzzle, part reflex test, completely addictive.

How a Game Unfolds

Every game starts slow. Early pieces fall lazily while you build a clean, flat tower with one open column — the “well” — for long-bar four-line clears. As you clear lines, the level rises and speed creeps up. Mid-game brings pressure: pieces come quicker and the well gets messy. End-game is pure survival — blocks rain down, you patch holes frantically, and one bad piece buries you. The game ends when the stack hits the top.

Controls

Left & Right Arrows / A & D — Move the piece sideways
Down Arrow / S — Soft drop (piece falls faster while held)
Up Arrow / W — Rotate the piece
Spacebar — Hard drop (piece slams down instantly)

From First Game to Line-Clearing Machine

Keep the stack flat. A flat surface fits every piece; a jagged skyline fits none.

Save the well. Leave one edge column open and feed long bars into it for four-line clears.

Rotate early. Decide rotation the moment a piece appears, not as it lands.

Use hard drop. Spacebar locks pieces in instantly — faster, and it trains your speed.

Do not chase the Tetris early. Singles and doubles keep you alive longer than waiting for the perfect setup.

Fix holes immediately. A buried hole is a time bomb — patch it before it goes deeper.
