Glitch City is a common term used for any area in a Pokémon game messes up by means of a glitch. The most well-known example of this is the Glitch City from the Red, Blue, and Yellow versions. "Glitch City" does not refer to when the game's colors are altered among other minor things. This is known as Glitch Dimension. Some glitched areas in Pokémon Red, Blue, and Yellow are named after what area was altered to create it. Examples of this are "Glitch League", accessed by taking the 500th step at the Pokémon League, and "Glitch Mountain", accessed by taking the 500th step on Cycling Road.
