Tetris Unblocked is the timeless block-stacking puzzle: tetromino shapes fall from the top of the board and you move and rotate them to form complete horizontal lines, which then clear. The blocks fall faster as you level up, and the game ends when the stack reaches the top. Click Play above to start instantly in your browser; no download, no sign-up.
Keep your stack flat and low. Beginners create tall towers and jagged gaps; good players build a smooth, even surface with a single well-placed gap on one side reserved for the long I-piece. Always look at the 'next' piece preview so you can plan the current drop around what's coming. Clearing single lines is fine early — but leaving room for bigger clears is where the real scoring lives.
Left/Right arrows move the piece, Up arrow (or X) rotates it, Down arrow soft-drops (speeds descent), and Spacebar hard-drops it instantly. Some versions use Z for counter-rotate and C to hold a piece for later. On mobile, swipe to move and tap to rotate. Simple controls, endless depth.
