Tetris

The thing is to drop blocks, called tetrominoes, down into a playing field to make lines. Tetriminoes are made of four connected places each (1) There are seven different types of tetrominoes. (1) Situations have a set thing, or number of lines to clear. When the thing number reaches zero, the player moves to the coming position. As the situations go over, the tetrominoes fall briskly. A player receives perk points if he can clear further than one line with a single tetromino. Clearing four lines is called a"tetris", three lines a" triadic"and two lines a" double". (4) 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- niche, to get further points.
