The line is made up of a square block. The Tetrimino is the shape of the 4 connected blocks that fall down. The player will have to use the Tetrominos to create lines that fill the box. This will clear the lines of blocks. The game continues, the lines of blocks that is not completely filled will drop down as many lines that were cleared. The game has levels of difficulties which rises as the game is being played.

Gameplay[change | change source]
The goal is to drop blocks, called tetrominos, down into a 10x20 block playing field to make horizontal lines. Tetriminos are made of four connected squares each  There are seven different types of tetrominos. Levels have a set goal, or number of lines to clear. When the goal number reaches zero, the player moves to the next level. As the levels go up, the tetrominos fall faster. A player receives bonus points if he can clear more than one line with a single tetromino. Clearing four lines is called a "tetris", three lines a "triple" and two lines a "double". Clearing two tetrises in a row is called a back-to-back tetris. The player can also turn a T-shaped tetromino into a hole, called a T-slot, to get more points. This move is called a "T-spin". In older versions of the game, the player loses when the tetrominos make it to the top of the playing field. In more modern versions of the game, the can lose in two ways. The first is when they place a piece completely above the playing field. The second way to lose is if a player places a piece that blocks the next piece from spawning in.[source?]
