Tower of Hell is a building jointly constructed in 1987 by Mayor uwuPyxl and Mayor VulpineDigital where citizens must reach the top of a 6-section building in 8 minutes. The building plays music. The timer's speed is doubled for every player who makes it to the top. There are no checkpoints; citizens must make it to the top before the time is up. The building changes its sections regularly and sometimes there are sections that are meant to be confidential. There are some buildings that are aimed for professionals and some of the sections in the building are actually creations by the citizens. Some of the sections were later removed.

By making it to the top repetitively, citizens earn coins, a currency that can only be spent inside the building. It can be spent on temporary items in the shop. The citizens will also gain levels. Citizens can visit the Skill Tree in the basement of building, where the tree's magical powers will upgrade their temporary items if their level is high enough.

Citizens who make an appointment to use this building can control the timer in the building, skip some sections of the building, and evict citizens from the building via the building's main computer station by typing in commands.
