Hidden areas refer to levels in Ripple Dot Zero that are unlocked by landing on a secret or concealed particle field. A hidden area is always found in the second level of an overall stage (eg. Ripple Laboratories, Crater Lake, etc.). All hidden particle fields except for Terrarium Area 2 contribute to the player's "secrets" count.

When a particle field leading to a hidden area is landed on, the level is completed. The map then unlocks the hidden area, designated by a turquoise coloured dot. Players must complete the hidden area or land on the normal particle field found in the previous level in order to lock the next regular stage.


Almost all hidden areas allow the player to gain an extra life by collecting capsules to fill the 1up metre in the bottom-right corner of the screen. The only exceptions are the hidden areas within Terrarium Area 2. The first, called the Terrarium, gives the player access to all uncompleted bonus stages, while the second allows players to visit a room that contains unused enemies and other components.
