About This Game

As the Great Downpour continued to flood the world, desperate hands built the Typhon Obelisk to swallow the endless oceans... before it was abruptly abandoned.

Experience the first-ever first-person Sudoku horror as you descend the reverberating infrastructure of the obelisk layer by layer. Solve Sudoku, run, and hide as you unravel what kind of horrors lie within. Will you be able to successfully rejuvenate the obelisk back to life and save the world from drowning?

SUDOKU... BUT HORROR

Solve randomly generated Sudoku puzzles of varying difficulties with their accompanying dark levels and environments. No level plays out the same.

YOU ARE NOT ALONE

Something's moving between the pipes of the Typhon Obelisk... Better lay low and avoid making mistakes; you do not want to draw its attention.

RISK VS. REWARD

Utilize scattered devices and machinery around you to better your chances of survival. Are you willing to sacrifice a save station in order to solve a random cell in your challenging Sudoku puzzle?

VARIOUS GAME MODES

Hungry for something extreme? Challenge yourself to an enduring one-life run in the Endless game mode, or perhaps a Daily Run would be more your style? If you ever feel crafty, design your own VIVARIUMS experience in the Custom game mode. Go nuts.
