There are many types of rooms in UnderMine. These rooms include:
Normal rooms[edit | edit source]
Secret rooms[edit | edit source]
These rooms must be blown into with any sort of an explosion. If there are sparkles on a wall, it has a secret room behind it. Sparkles can be revealed with any kind of an explosion in the room. They may contain one or more Blessings, treasures, puzzles, items, and so.
Secret rooms can be bombed out of into locked rooms, saving a key from being used.

These rooms contain shrines. The player may pray at a shrine for a blessing at the cost of a curse, or pray to get rid of a curse at the cost of health. For more info, see Altar, Blessings, and Curses. The room may be found locked.

"Too mysterious altar" - Relic Altar[edit | edit source]
This room does not have a proper name yet. It can spawn on any floor. This room is locked behind a cursed door requiring 1 major curse to open. This new altar acts as a bank for a relic. The relic placed on this new altar is stored for future runs. If Mune is deposited, it will be replaced by Masa on the next run. This phenomenon was not confirmed or denied by devs.
