TETRIS

About TETRIS Unblocked

TETRIS unblocked is available to play for free online. TETRIS is the timeless puzzle classic created by Alexey Pajitnov in 1984 that became a global phenomenon and remains one of the most addictive games ever made. This multiplayer version brings the iconic falling block gameplay to competitive online matches. Seven different Tetrimino shapes (I, O, T, S, Z, J, L) fall from the top of the playing field, and you must rotate and position them to create complete horizontal lines. When a line is filled, it clears and you earn points. The game features clean minimalist graphics that keep focus on the pure gameplay, progressively increasing speed that intensifies the challenge, hold function to save a piece for later, ghost piece preview showing where blocks will land, and multiplayer mode to compete against opponents. As lines clear, the speed accelerates, testing your spatial reasoning and reflexes. Master the art of Tetris with T-spins, back-to-back Tetrises, and perfect clears!

How to Play

• Control Tetriminos: Use LEFT/RIGHT arrows to move pieces horizontally, UP arrow or X to rotate clockwise, Z to rotate counterclockwise, DOWN to soft drop.
• Create complete lines: Arrange falling Tetriminos to fill horizontal rows completely. Filled rows disappear and award points. Clear multiple lines simultaneously for bonus points.
• Use Hold function: Press C or SHIFT to hold the current piece and swap it with the held piece. Use this to save I-pieces for Tetrises or save difficult pieces for later.
• Competitive strategy: In multiplayer, clearing multiple lines sends garbage rows to opponents. Tetris clears (4 lines) and T-spins are most effective. Keep your stack low and build combos for sustained pressure.

Game Tips & Strategies

• Keep your stack as flat as possible - avoid creating high peaks and deep valleys
• Save the I-piece (long straight piece) in Hold for when you need a Tetris (4-line clear)
• Build on the sides and leave a vertical well on one edge for I-piece Tetrises
• Learn T-spin setups - they clear lines and send more garbage in multiplayer
• Use hard drop (space bar) to place pieces instantly once positioned
