Tetris Unblocked

Tetris Unblocked is a 2D puzzle game, one of the most well-known video games. Your main objective in this game is to create horizontal lines on the playing field. To do that, you must use the falling blocks in the best way possible.

Clearing a horizontal line causes the blocks within it to vanish. Remember that you can’t leave any space in the lines. This way, you will make progress and get scores!

The Falling Tetriminos

  • The falling blocks are called Tetriminos in this puzzle game. They will come in various shapes.
  • Your biggest challenge is to arrange these blocks of different shapes side by side, orienting them so that there is no gap between them.
  • Place them inside the Matrix by rotating, moving and dropping them.
  • If you fail to clear out the lines, they will eventually create an avalanche on the playing field.
  • The game will be over when the top of the Matrix is full of blocks.
  • Additionally, keep in mind that as you level up, Tetriminos will fall faster, making your job more challenging.

The Ghost Piece

Bringing the blocks together without leaving any space is a tough task. However, the Ghost Piece can help. It will tell you the best position for the falling Tetrimino in a specific line.

The possible placements are displayed automatically. Otherwise, manually maneuvering a block makes the job even more difficult. Using the Ghost Piece, especially in later levels, is a must, as Tetriminos will fall faster!
