A player enters one of many placeholder maps which the game denotes as 'Mystery Zone' consisting of several rows of trees in Pokémon Platinum.
In the Japanese versions of Pokémon Heartgold and Soulsilver, for unknown reasons placeholder maps are named '----'. In the English versions, they are named 'Mystery Zone'.
In the Generation IV handheld Pokémon games; a 'Mystery Zone' (Japanese: なぞのばしょ Mystery Place) in Pokémon Diamond, Pearl and Platinum, or (Japanese: ----) in Pokémon HeartGold and SoulSilver refers to any of many areas which act as placeholders in between multiple areas normally accessible within the game. These maps also correspond with tunnels in the underground which are normally inaccessible without the player moving around first.
Essentially the 'Mystery Zones' act as error handlers for the undefined areas surrounding real routes or as fillers when considering Sinnoh as two large maps being the normal areas and the underground. When a player travels through a Mystery Zone he or she is unable to open the menu or even operate the touch screen; therefore it could be suggested a blank map is used to ensure that the player cannot open the menu before they even proceed past the title screen.
These areas are most commonly seen consisting of either blank space, several rows of trees, water or any combination of these features. Whilst in the Mystery Zone the music for Routes 206, 207, 208 and 211 usually plays; however the Mystery Zone plays a slightly off-key version of these routes. This music corresponds to its own unique variable and is normally never used in game. In HeartGold and SoulSilver, the Route 29 theme is played instead.
Procedure (Diamond/Pearl/Platinum), (Heartgold/Soulsilver)
This is the most common method players have used to access a "Mystery Zone".
- Use a game-altering device to walk through walls.
- Attempt to move through objects surrounding the area into areas which are normally inaccessible.
Alternative methods for accessing the Mystery Zones without a game-altering device
- Players can use the Tweaking Glitch to take advantage of an error concerning how the game handles accessible areas within the game.
- On early versions of Japanese Pokémon Diamond and Pearl games the Surf through Elite Four door glitch allowed players (as the name of the glitch suggests)to be able to surf through the first Elite Four member's door and then be able to walk through an extremely large area of blank space whilst passing various Mystery Zones and even areas such as Flower Paradise which are normally inaccessible without a special Nintendo event.
