Tetris (Russian: Те́трис) is a puzzle video game originally designed and programmed by Alexey Pajitnov in the Soviet Union. It was created on June 6, 1984, while he was working for the Dorodnicyn Computing Centre of the Academy of Science of the USSR in Moscow. He derived its name from the Greek numerical prefix tetra- (all of the game's pieces, known as Tetrominoes, contain four segments) and tennis, Pajitnov's favorite sport.

Dr. Mario (Dr. マリオ) is an arcade puzzle video game produced by Nintendo. It was originally released as an arcade version in 1990, and adapted for the Nintendo Entertainment System and Game Boy the same year. Its play mechanics are compared to Tetris. In this game, Dr. Mario throws vitamins that the player must align in order to destroy the viruses that populate the playing field (designed to resemble a medicine bottle).
