Play Tetris Online

Use arrow keys to move and rotate pieces: Left/Right arrows move horizontally, Down arrow soft drops, Up arrow rotates, Space bar hard drops. Clear horizontal lines to score points. The game speeds up as you level up. Press P to pause.

Arrow keys control movement: ← moves left, → moves right, ↓ soft drops (faster fall), ↑ rotates piece 90 degrees clockwise. Space bar performs hard drop (instant drop to bottom). Press P to pause/unpause the game.

Score points by clearing horizontal lines. Single line: 40 × (level + 1), Double: 100 × (level + 1), Triple: 300 × (level + 1), Tetris (4 lines): 1200 × (level + 1). Higher levels multiply your score. Level increases every 10 lines cleared.

A Tetris is clearing 4 lines simultaneously with a single piece, earning the highest score multiplier. It's achieved by stacking pieces to create a vertical column of 4 complete lines, then dropping an I-piece (vertical line piece) to clear all 4 at once.

Press the Up arrow key to rotate the current piece 90 degrees clockwise. The piece will rotate around its center if there's space. If rotation would cause the piece to overlap with existing blocks or go out of bounds, the rotation won't occur.

Cleared lines disappear, and all blocks above fall down to fill the gap. This creates space for more pieces and prevents the board from filling up. Clearing multiple lines at once (2, 3, or 4) awards exponentially higher scores.

You start at level 1. Every 10 lines cleared increases your level by 1. Higher levels make pieces fall faster, increasing difficulty. Each level also multiplies your score, so clearing lines at higher levels earns more points.

Soft drop (Down arrow) makes the piece fall faster while still allowing you to control it. Hard drop (Space bar) instantly drops the piece to the bottom, locking it immediately. Hard drop is useful for quick placement but gives less time to position.

Press the P key to pause or unpause the game. When paused, the game stops and displays a pause message. This is useful for taking breaks without losing your progress. The game state is preserved exactly as it was when paused.

When pieces reach the top of the board and a new piece can't spawn, the game ends. Your final score, level, and lines cleared are displayed. Click 'Restart' to begin a new game and try to beat your high score.

Yes! This Tetris game works on mobile devices. Touch controls can be used, though keyboard controls provide the best experience. The game is fully responsive and adapts to different screen sizes.

The 7 standard pieces are: I-piece (line), O-piece (square), T-piece (T-shape), S-piece, Z-piece, J-piece, and L-piece. Each has a unique color and rotation pattern. Learning each piece's characteristics helps improve gameplay.

Practice regularly, learn piece rotation patterns, plan ahead by looking at the next piece, keep the board flat (avoid creating peaks), leave space for I-pieces to clear multiple lines, and use hard drop strategically. Focus on clearing lines efficiently rather than just surviving.

Theoretically unlimited, as Tetris continues until you lose. High-level players can score millions of points by maintaining long games at high levels. Competitive players often measure skill by lines cleared and survival time rather than just score.
