Short description
Descend the Typhon Obelisk in the first-ever blend of classic Sudoku and first-person horror.
About this game
Experience the first-ever first-person Sudoku horror as you descend the reverberating infrastructure of the Typhon 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 atmospheric levels and environments. No layer plays out the same. YOU ARE NOT THE ONLY ONE SOLVING SUDOKU Something's moving between the endless 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? The choice is yours... DIFFERENT WAYS TO PLAY 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.
