Paradiegetic (noun): From Greek πέρα para- meaning "Beyond" and diegetic meaning "The confines of the medium".
Most games you can beat without having to get up from your chair, provided you don't need to use the bathroom. Sometimes, though, a puzzle's solution involves something that isn't in the game itself, and beating it will require you to do something that isn't just pressing buttons on your keyboard or controller. Maybe it involves a phone number you have to call, or you need to fiddle with the date and time in Windows settings, or press the "eject" button on your CD drive. This is where this trope comes in.
These types of puzzles may lead to Guide Dang It! since most people often don't expect this sort of gameplay.
Sometimes these types of puzzles are done as a form of Copy Protection, having Feelies bundled with a physical copy of the game with an answer to a puzzle to prevent those who downloaded the game on the Internet to solve it and continue.
Extrinsic Go-First Rule is a subtrope. See also Breaking the Fourth Wall and Logging onto the Fourth Wall, which is similar however is simply Played for Laughs or as an Easter Egg. Also see Unexpectedly Realistic Gameplay and Unexpected Gameplay Change. The Other Wiki calls it a pervasive game.

Opening it up would begin a minigame where you close the DS again and use the L and R buttons to help Daffy chase after the beast (who turns out to be Gossamer). Arbitrarily, you could only try this once per day; after that it would go into Sleep Mode as normal.

- In the tabletop Room Escape Game series Exit The Game, while most of the game's puzzles make use of the cards, booklet, and various Feelies included in the box, there's always one puzzle in each game that somehow makes use of the box itself.

- In the Famicom Disk System version of The Legend of Zelda, the Pols Voice enemy is killed by yelling in the microphone in the Famicom's second controller. Each Japanese rerelease changes it so Pols Voice can be killed with a different method, such as pressing Select 4 times in the GBA version, or pressing L and R to virtually "switch" to the second controller and yell into the 3DS's microphone in the 3DS version. In all English releases, including the NES version, the enemy is instead weak to arrows.

In-game, these are artifacts from which the monsters are generated in a lab; out of game, the player has to put a different CD or game disc into the PlayStation, which generates the monster's stats from its subcode data. Later games in the line add different input methods, like the DS microphone and touchscreen.

- The X-Men game for Sega Genesis requires you to perform a soft reset on the console before you can enter the final level.
- The last Text Adventure in the Zork series, Zork Zero, consisted half of stock puzzles and half of this as a form of Copy Protection. The solution to puzzle after puzzle was simply to pull a specific bit of trivia out of the game's Feelies and type it in.
