How to save in Dungeon

To save your progress in Dungeon, you can use special levers. These levers are located on every 5th floor of Dungeon. They look like this:

When you pull a lever, you activate a checkpoint four floors down.

Thus, by pressing the lever on the 695th floor, you can start clearing Dungeon from the 691st floor the next day.

You receive bonus gold for activating a lever.
