The game's arcade machine is located in Litwak's Arcade. It is accessable to players through the simple insert of a quarter, while game avatars can access it through the surge-protector.
The entire world takes place in an 8-bit era game. because of this, the entire game operates on a pixelated, square-shaped set of physics and design, many of its details are left basic and flat. The sky is left in perpetual night, with the screen where the player is facing the front of the apartment. Off screen there is a trolley that can be found in other games as well, used as a way to enter and exit the game to/from the surge protector. The game is a clear parody of the 1980's Nintendo game Donkey King.
Like all the games in the arcade, Fix-It Felix, Jr. has its own built-in plot and backstory for the characters.
- Ralph's forest home is destroyed by construction of a new apartment building. Angered, Ralph shouts out, "I'm gonna wreck it!" and begins to demolish the building by destroying the windows. As Fix-It Felix comes in to save the day, Ralph throws down bricks at Felix, who must dodge them and fix the broken parts with his hammer, eating pies given to him to become temporarily invincible.
- At the end of the game, the Nicelanders throw Ralph off the top of the building, having him unceremoniously fall into a pile of mud, while the tenants of the building present Felix with a medal, thus ending the game.
A large apartment building where the Nicelanders and Felix reside. The penthouse of the building is known for hosting parties, such as the party for the game's 30th anniversary, and is where Gene lives.
Where Ralph sadly lived until he turned it into some homes for himself, Q*bert and his friends, as well as other homeless video game characters. (with some help from Fix-It Felix) During the finale, the dump was renamed East Niceland.
The forest that surrounds the whole game.
The Trolley that serves as a transport from Niceland to Game Central Station and back.
