Tetris Strategy: Tips That Take You From 4 Lines to a Tetris
Flat stacking, the well, and how to actually score a four-line clear
Score real Tetrises (four lines at once) by keeping your stack flat and low, leaving one column — the "well" — empty on one side, and saving your long I-piece to drop straight down that well for a four-line clear. Place every other piece flush so you never create overhangs or holes, and clear lines before your stack climbs into the danger zone.

Frequently Asked Questions
What is a Tetris in the game Tetris?
A "Tetris" is clearing four lines simultaneously with a single vertical I-piece dropped into a one-column gap (the well). It is the highest-scoring single move in the game — worth far more than clearing four lines one at a time — which is why advanced players build their whole stack around setting it up.
How do you keep your Tetris stack from topping out?
Stack flat and low, and never leave holes you cannot reach. Each piece should sit flush against the surface beside it; an overhang traps an empty cell that can only be cleared by removing everything above it. Clear lines before the stack climbs past about two-thirds height, and do not hoard the four-line plan if you are about to die — just survive.
What is the well in Tetris strategy?
The well is a single column you deliberately keep empty (usually the far left or right) so you can drop a vertical I-piece into it for a four-line clear. You build the other nine columns up evenly and feed the well only with I-pieces. Discipline matters: do not accidentally fill your own well with the wrong piece.
Should you always go for four-line clears in Tetris?
Go for them when your stack is healthy, but survival comes first. If your stack is getting dangerously high or you have not seen an I-piece in a while, clear whatever lines you can to bring it down. A clean single clear that keeps you alive beats a greedy four-line plan that tops you out.
How do you get better at Tetris fast?
Three habits: keep the surface flat so any piece fits somewhere clean, maintain one open well for I-pieces, and think one piece ahead using the next-piece preview. Avoiding holes matters more than clearing fast — a board with no holes is always recoverable.
