How to play Tetris
I move pieces with the arrow keys or WASD, rotate with the up arrow, and slam a piece down with the spacebar. On a phone I use the on-screen buttons to slide, rotate, and drop.
I clear a row by filling it completely across. Clearing more rows at once scores more, and the speed ramps up every ten lines, so I try to keep the stack low and flat.
About Tetris
Tetris was born in Moscow in 1984, written by Alexey Pajitnov on a Soviet Electronika 60 that could not even draw graphics, the first pieces were bracket characters. It escaped the USSR through legendary licensing battles, boarded the Game Boy in 1989, and became what many consider the most successful video game of all time, with over half a billion copies sold across platforms.
Its seven tetrominoes and one rule, complete a line and it vanishes, produce a game with no final state, only degrees of control. Researchers have named the 'Tetris effect' after the way its shapes invade players' idle thoughts. Modern play revolves around the guarantee that all seven pieces appear once per 'bag', turning apparent chaos into plannable sequence.
Tetris stacking craft
- Keep your stack flat and low; height is debt, and every hole you bury costs multiple lines to expose again.
- Build for Tetrises: keep one column (usually the far right) empty and feed it I-pieces for four-line clears.
- Use the next-piece preview relentlessly, place the current piece to serve the next one, not itself.
- Learn soft-drop control before chasing hard-drop speed; misdrops kill more games than slowness ever will.
- The S and Z pieces create overhangs; place them early against flat ground instead of saving them for emergencies.
FAQ
What is the 7-bag system?
Modern Tetris deals pieces in shuffled sets of all seven tetrominoes, so you are never starved of any piece for long, at most 12 pieces can separate two I-pieces. Once you know the bag rhythm, you can plan Tetris wells and recoveries with real confidence instead of hope.
Why should I save a column for four-line clears?
A Tetris (four lines at once) scores dramatically more than four singles. Building a clean nine-wide stack with one empty well, then dropping an I-piece in, is the fundamental scoring strategy at every level of play, and it teaches the flat-stacking discipline that keeps you alive.
What kills most Tetris runs?
Buried holes. A single covered gap turns into a tax you pay for many pieces, and panic-stacking on top compounds it. When you make a hole, shift strategy immediately: clear down to it while the speed is still manageable, even at the cost of scoring tempo.
Does the game ever end?
Marathon-style Tetris only ends when the stack tops out, speed keeps climbing until survival, not scoring, is the game. That crescendo is by design: Tetris is not meant to be beaten, only outlasted a little longer than last time. Best score is saved locally.
