What is Tetris?

Tetris (Russian: Тетрис) is an early video game designed and developed by Soviet computer scientist Alexey Pajitnov. The game was created on June 6, 1984, while he was working at the Dorodnitsyn Computing Center of the USSR Academy of Sciences in Moscow. He took the name of the game from the Greek prefix “tetra- ”, which means “four” (each division in the game, called Tetromino, has four parts) and tennis (tennis), the sport game. Sports Pajitnov likes the most.

Games (or a variation thereof) are sold for virtually any video game console and computer operating system, as well as in graphical computers, mobile phones, portable music players, PDAs, and many other things. While many variants of Tetris were marketed in the 1980s, the Game Boy’s handheld game, released in 1989, made the game one of the most popular. The 100th issue of Electronic Gaming Monthly magazine called Tetris “The Greatest Game of All Time”. It has sold over 70 million copies.

The game has seven types of blocks: I (vertical), J, L, O (square), S, T, Z. We see each brick block is composed of 4 small squares put together. We can think of these blocks as rectangles of different sizes.

Other shapes are created when these basic blocks are rotated 90 degrees, 180 degrees, 270 degrees respectively.

A random sequence of Tetriminos falls on the playing field (a rectangular vertical axis, called “good” or “matrix”).


The goal of the game is to move the slowly falling bricks in a rectangle size of 20 rows x 10 columns (on the screen). Where there are bricks, you cannot move to that position. Players arrange the blocks so that the block fills a horizontal line to score points and the horizontal line will disappear.

We have two tables:

  • A main table with 24 rows and 10 columns. We will only show the screen 20 lines and the other 4 lines will not. Why? Because when we create a new block to fall down, we will create about the top 4 lines. And the player will not see it until it is gradually revealed.
  • A Next table shows the next blocks that will be added to the screen when the current block has been placed. 
  • A group of 4 blocks will fall from the top of the screen, move the blocks and rotate them until they fall to the bottom of the screen, then the next group of 4 blocks will fall.

If the blocks are too high on the screen, the game will be over.

The game ends when the blocks can no longer fall.

All Tetriminos have the ability to complete one and two lines. J, L can have three. Only the letter I Tetrimino has the ability to erase four lines at once, and this is called a “Tetris”. Delete at most only 4 rows/1 time.

Shortcut keys:

  • Up arrow key: rotate the block.
  • Left arrow key: move left.
  • Right arrow key: move right.
  • Down arrow key: increase the falling speed

Difference Between Tetris Unblocked

The main difference between the original game and Tetris unblocked is that the latter provides a different playing experience. Instead of blocks falling from top to bottom, you have complete control over where they fall on the screen. The scoring mechanism works both horizontally and vertically. Tetris’ gameplay is completely altered by a few minor changes.

Tetris Unblock Tips And Tricks

Play The Game In Reverse

The first thing you should do is flip the game over. You’ll have to fit the pieces in from left to right instead of right to left this way. This causes the pieces to fall from different sides of the grid, making it much more difficult to fit them all. Another thing to do is to rotate your device. This will alter the angle from which you view the game. You’ll be able to see the pieces falling from various angles this way.

Rotate Your Device To Change The Perspective

To change the perspective, you must now rotate your device. This will cause you to see the game from a different perspective. This will allow you to see the pieces falling from different angles, making it easier to fit them.

Use The Mouse To Rotate Blocks

You should now rotate the blocks with the mouse. You will be able to rotate them in 3D space this way. By pressing and holding the left mouse button on a piece and then moving your mouse, you should be able to control the rotation. Another tip is to rotate a block clockwise with the left mouse button and counterclockwise with the right mouse button.

Clear Out Unreachable Rows And Columns

You should now remove any unreachable rows and columns. You’ll be able to see the other pieces that you can fit into the grid this way. Begin by removing all of the rows that you cannot reach. After that, you’ll be able to see all of the possible pieces that can fit in the grid. You’ll want to do the same thing with the columns now. Begin by removing the columns you can’t reach. After that, you’ll be able to see all of the possible pieces that you can fit into the grid.

Push Your Device Back While Playing The Game

While playing the game, you should now push your device back. This will cause you to see the falling pieces from a different perspective. This will allow you to see the pieces falling from different angles, making it easier to fit them.

Avoid Placing Blocks On Top Of Each Other

This is one of the most important things you can do to improve your Tetris skills! Avoid putting a piece on top of another. If you do this, you will be able to fit more pieces in the grid because the pieces you are placing will be on a lower row than the other pieces. If you place a piece on top of another, you will be able to fit fewer pieces in the grid because the pieces you are placing will be on a higher row than the other pieces.

Watch Out For These Common Mistakes

These are just a few of the things you should keep in mind while playing the game. There are numerous other things you can do to improve your game, so keep them in mind! – Failing to fit a piece because you failed to rotate your device and see the pieces fall from a different angle. – Failing to place a piece because unreachable rows or columns were not cleared out. – Failing to push back your device while playing the game. – Failing to rotate the blocks in three dimensions.


You’ll eventually build a mound higher than two blocks, no matter how well you play. If at all possible, Neubauer recommends biasing your mounds to the center of the playing field in most versions of Tetris. However, if you’re playing Tetris on the NES like he is, he recommends tilting the screen to the left.

Building mounds in the center of the playing field will give you more chances to flatten the playing field in all modern versions of Tetris.


Tetris is a great game to play on your phone or tablet because it is portable and doesn’t require you to find a place to plug in your device and play. The best part is that it is completely free and requires no download! You only need an internet connection, your device, and a little patience. This game may appear simple at first, but it becomes much more difficult as you progress through the levels. When you’re sick of playing the same level over and over, look for new ways to play.
