Vivariums

Vivariums is a first-person horror game set in the Typhon Obelisk, a vast structure you descend through layer by layer. You solve Sudoku puzzles, run and hide from the horrors inside, and try to rejuvenate the obelisk to save the world from drowning.

The Typhon Obelisk

The obelisk’s layers contain atmospheric environments and randomly generated Sudoku puzzles of varying difficulties. No layer plays out the same way. Something moves among the endless pipes, so you need to avoid mistakes that could draw its attention.

Survival and risk

Scattered devices and machinery can improve your chances of survival. Some choices carry a cost: for example, you can sacrifice a save station to solve a random cell in a difficult Sudoku puzzle.

Game modes

• Endless: attempt a run with only one life.
• Daily Run: take on a daily run.
