About This Game

Souterrain is the occult dice and deck roguelike where you save your soul by manipulating dice to drive the score up.

Deep below a mysterious occult store there is a casino, where the guests gamble with their most valuable possession... their souls. How unfortunate that you have found your way here. You have no choice, you must roll the dice, manipulate fate, cheat the house, and save your own soul.

How will you play? There are dozens of possibilities and plenty of synergies to enable countless strategies.

• Will you spawn ghost dice? Ghost dice disappear after being counted, but drive the score up quickly.

• Maximize multiplier? Increasing the mult brings the score up faster than collecting souls. How high can you make it?

• Add up modifiers? Adding modifiers to a die increase its count for that round, an invaluable tool to the savvy gambler.

• Will you discover a better strategy?

Every roll is a gamble, and every hand brings a new opportunity. Build your strategy, discover powerful synergies, and turn a desperate wager into an unstoppable run.

• 100 curios that give powerful passive buffs. This is the core of any good run

• Over 175 spell cards to manipulate fate. These are your best friends in Souterrain.

• Over 25 useful consumable tokens. Everyone needs a pick me up sometimes.

• 14 dice boxes with 8 difficulties for dozens of unique run possibilities.

Face increasingly dangerous opponents and powerful bosses, each with their own tricks to bring your descent to an early end. The house always has an advantage. You'll need every trick you can find to survive.

Your soul is the ultimate stake. How far are you willing to go to keep it?
