Location modes alternate absolutely randomly and change only after a location has been successfully explored.
Some quests require specific location modes.
If you get the message "this mode is currently unavailable," this means that you can only find the object you are looking for in a certain location mode.
To change any location's mode, you need to explore it until the required mode appears in it.
It is also impossible to summon a specific mode to a specific location.

There are seven location exploration modes:
Text mode: you are given a list of objects you need to find.

Silhouette mode: you are shown the silhouettes of the required objects.

Night mode: you are given a list of objects as text, but the location is darkened.

Match mode: you need to find identical objects hidden in a location.

Morph mode: you need to find objects that transform and change into other objects.

Anagram mode: in this mode, the letters in the names of the objects on the list are scrambled.
Difference mode: in this mode, you need to find differences between locations.
Five mode: in this mode, you need to find sets of 5 identical items.
