About Tetris Unblocked

Tetris unblocked is available to play for free online. Tetris is the legendary puzzle game that defined an entire genre and remains one of the most influential video games ever created. Guide falling geometric shapes called Tetriminos - composed of four connected blocks in seven distinct patterns (I, O, T, S, Z, J, L) - as they descend from the top of the playfield. Rotate and position each piece to create complete horizontal lines across the 10-block-wide grid. When a line is fully filled with blocks, it clears and earns you points. The game features gradually increasing speed that tests your reflexes, the iconic falling-block gameplay that's instantly recognizable worldwide, satisfying line-clear mechanics with bonus points for clearing multiple lines simultaneously (single, double, triple, or the coveted Tetris - four lines at once), and a perfect difficulty curve that's easy to start but increasingly challenging. As you clear more lines, pieces fall faster, demanding quicker decision-making and precise placement. The simple goal of preventing blocks from stacking to the top creates endless strategic depth. With its timeless gameplay, instantly recognizable shapes, and the famous Russian folk melody "Korobeiniki" as its theme music, Tetris has captivated players for nearly 40 years across every gaming platform imaginable.

How to Play

• Rotate and move pieces: Use arrow keys - Left/Right to move pieces horizontally, Up to rotate clockwise, Down to drop faster. Pieces automatically fall downward.
• Complete horizontal lines: Position pieces to fill entire rows across the 10-block width. Completed lines disappear, and blocks above drop down.
• Avoid reaching the top: If your stack of blocks reaches the top of the playfield, the game ends. Clear lines to keep the stack low.
• Master Tetris clears: Clearing four lines simultaneously with an I-piece earns massive bonus points. Build a vertical gap and wait for the long piece. Survive as long as possible!
