Tetris TetrisTetris is the puzzle game that has been impossible to put down since 1984 — and here it is, free in your browser. Drop falling tetrominoes into a 10-column well, complete rows to clear them, and survive as the pieces fall faster and faster across 100 levels. No downloads, no accounts, no sign-ups: open the page and you're playing in seconds.
Seven different shapes — the I, O, T, S, Z, J, and L tetrominoes — fall one at a time into a narrow well. Your job is to rotate and slide each piece so it settles into the stack, filling complete horizontal rows. Every finished row disappears, earns you points, and drops everything above it down one line.
The rules are simple to learn and famously hard to master: keep the stack from reaching the top. The longer you survive, the faster the pieces fall — and the more your planning is put to the test.
Desktop: Left/Right arrows to move, Up to rotate, Down for a soft drop, Space for an instant hard drop.
Mobile: on-screen buttons for move, rotate, and drop, laid out for one-thumb play.
Clear one line for 100 points, two for 300, three for 500, and four at once — a "Tetris" — for a full 800. Two features help you score big: a ghost outline shows exactly where your current piece will land, and a next-piece preview lets you plan two moves ahead. Clear four lines in a single drop to earn the game's biggest payoffs.
Tetris was designed in 1984 by Soviet engineer Alexey Pajitnov and went on to become one of the best-selling games in history.
