Level 66 is the 67th Level of the backrooms It is right now an unconfirmed level.
Description
Level 66 appears as a Swamp, similar to the Florida everglades. This level is devoid of entities, except for death rats that swim in the swamp water. It is hard to navigate this level, since there are no pathways. You may easily lose your sanity, but drinking enough almond water can help you. The swamp water seems to be able to drive you into insanity, so it is not recommended to drink it.
Entering and Exiting Level 66
You can enter Level 66 by going too far into Level 34 or Level 10. It is possible to exit level 66 by finding a long road deep within 66. If you follow it, you will end up in Level 11.
