Tetris

Puzzle video game

Tetris (Russian: Тетрис) is a puzzle video game created by Alexey Pajitnov, a Soviet software engineer, in the mid-1980s. In Tetris, falling pieces consisting of four connected blocks, known as tetrominoes, must be sorted into a pile. Once a horizontal line of the playfield is filled with blocks, the line disappears, granting points and preventing the pile from reaching the top.
