Deck Heroes has multiple "Hidden Dungeons" within the Explorer's Gate that are unlocked by defeating specific Dungeons on that map on Hard Difficulty. Hidden Dungeons often offer rewards for winning on Easy, Normal and/or Hard, and also generally open up access to new Creature Cards through Exploration.
It is important to note that in order to gain access to Hidden Dungeons, the player needs to not only defeat the specific Dungeon on Hard, but also needs to open up a pathway to that select Dungeon on easy. For example, on Map 3 the player unlocks Dungeon 3-9 by beating 3-5 on hard. In order to access 3-9, however, the player will need to have won battles on easy up to and including 3-8.
The hidden dungeons can be recognized by the question mark symbol. For locked dungeons it will show as a greyed out symbol and for unlocked it will show as a gold symbol
