Cheat code

Cheat codes are built-in cheating mechanisms in video games that usually give the player considerable advantages, such as the ability to skip to any level regardless of progress, invincibility, or power-ups to the player character. Cheats are typically activated with unprompted button sequences in the game's menus or by accomplishing an obscure or illogical series of events within the game. Despite their name, cheat-codes do not always give the player an advantage, as something entered like a cheat-code may instead result in graphical changes or unlock extra content that does not directly benefit the player.
