Tetris

How to play

• Press Start Game, then use the left and right arrow keys to move the falling piece across the board.
• Press the up arrow (or Rotate button) to spin the piece, and the down arrow to soft-drop it faster.
• Complete a full horizontal line — with no gaps — to clear it; every cleared line adds 100 points to your score.
• On mobile, use the on-screen Rotate, Left, Down and Right buttons to control every drop.
• The round ends when the stack reaches the top of the board — keep it low and flat to survive.

Game description

Tetris is arguably the most famous puzzle game ever made — invented in Moscow in 1984 and unbeaten since as a test of spatial thinking under pressure. Seven tetromino shapes fall one at a time, and everything you know about the game is contained in one instruction: complete horizontal lines and they disappear. From that single rule grows the eternal drama of every Tetris round — the tidy start, the creeping mess, the desperate wait for a long piece while your mistakes pile toward the ceiling.

Our browser version delivers the classic experience with keyboard and touch controls and no installation. The skills it rewards are the timeless ones: keeping your stack flat, refusing to bury holes, and keeping one tidy well ready for the long I-piece. What separates casual players from good ones is not reaction speed — it is placement discipline in the calm moments, because the frantic endgame merely collects the bill for decisions made thirty seconds earlier. Every round is short, every restart instant, and the one-more-game pull is exactly as strong as it was four decades ago.

Tips & tricks

• Keep the stack flat and low — a level surface accepts every piece, while towers and canyons accept almost none.
• Reserve one column (usually an edge) as a well for the long I-piece, and cash it in for multi-line clears.
• Never bury a hole to place a piece quickly; one covered gap costs more than three slow placements.
• Rotate the piece to its final orientation early, high on the board, so the drop itself needs no last-moment decisions.
• Use the soft drop for control, not speed — slamming pieces down before deciding their spot is the classic beginner leak.

Tetris — quick answers

What do the different Tetris pieces do?

All seven tetrominoes are four-square shapes — the line, square, T, L, J, S and Z. Each fits some stacks beautifully and ruins others, which is why flat stacking matters: it keeps your board compatible with whatever falls next.

How do I score the most points?

In this version every cleared line is worth a flat 100 points, so the real high-score engine is survival — the longer your board stays healthy, the more lines you clear. Build flat, avoid buried holes, and treat every placement as an investment in the next ten.

Is this the full classic Tetris experience?

It is a faithful classic-style implementation: falling tetrominoes, rotation, soft drops and line clears, playable free on desktop and mobile. Pure fundamentals — exactly the skill set the original demands.
