On "Seinfeld", what video game is George a master of?

On “Seinfeld,” George is a master of Frogger. In the episode “The Frogger,” he discovers that his initials still hold the high score on the Frogger machine at his old high-school hangout.

Frogger is a 1981 arcade game developed by Konami and distributed internationally by Sega. Players guide a frog across a busy road and then over a river, avoiding cars, trucks, crocodiles, and other hazards. The game became one of the most recognizable arcade titles of the early 1980s.

The “Seinfeld” episode first aired on April 23, 1998, as the 18th episode of season nine. George’s obsession is not simply that he played the game well; he becomes determined to preserve his initials on the machine after realizing the cabinet is about to be moved. A common mix-up is confusing Frogger with other classic arcade games such as Pac-Man or Donkey Kong, but Frogger is the specific game central to George’s storyline.
