Tetris is a popular puzzle game developed and published in 1984 by Alexey Pajitnov, a Russian computer scientist.
The objective of the game is to rotate and place shaped blocks (called tetrominoes) on a horizontal line, creating a complete solid layer. The player does this by sliding the pieces into position. This continues until the player either forms a horizontal line or runs out of pieces to play with.
Tetris has been included in many different video games and platforms, including Facebook Tetris and Tetris Blitz. It has over 150 million registered players worldwide with over 20 million active monthly players at peak times.
