A tetris is a tile-matching puzzle game, developed in the Soviet Union in 1984. The game has a simple goal of destroying lines of blocks before it reaches the top. 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.
Tetris has appeared in many video game systems. It has become very common from back when Alexey Pajitnov first made it in 1984. With over 500 million copies sold across all of its different versions, it is the best-selling video game of all time.
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?]
