Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Early Access will let us refine the balance, clarity and variety of Numeromantia with players. We want feedback on builds, encounters and the choices that make each run interesting.”

Approximately how long will this game be in Early Access?

“We currently expect Early Access to last approximately three months. This is an estimate and may change based on feedback and development needs.”

How is the full version planned to differ from the Early Access version?

“We plan to refine balance, presentation and usability, expand and adjust content, and address problems reported during Early Access. The final scope may change as we learn from players.”

What is the current state of the Early Access version?

“The current version includes playable heroes, a complete campaign, Ascension difficulties, cards, artifacts, potions, events, bosses, content unlocks and run history. The core run loop is playable; balance and presentation are still being refined.”

Will the game be priced differently during and after Early Access?

“We do not plan to change the price during Early Access or when the game leaves Early Access.”

How are you planning on involving the Community in your development process?

“Share feedback through the in-game feedback form, Steam discussions or our Discord community. We will use bug reports and player feedback to guide improvements and share development updates.”

About This Game

Your cards have shapes. Your power is on the board. Numeromantia is a turn-based deckbuilding roguelike where the numbers beneath a card fuel its effects. A strong hand is only the beginning: you must also leave yourself room to use it.

No mana. Every number counts.

Place a card over the number board to attack, gain Block or prepare a combination. Used numbers are consumed, reshaping the choices left to you. Fill an entire card's area to trigger its Resonance, then plan around regeneration, sleeping cells and the enemy's next action.

Build a deck. Change the battlefield.

Raise numbers, transform metals and charge cells with elements or your hero's marks. A tempting large shape may bring a powerful effect, but also spend the space your next card needs. Cards, artifacts and potions work together: find a plan that makes the whole table yours.

Follow a different discipline.

The Alchemist combines elements, metals, potion brewing and Rebirth. The Oathkeeper builds Resolve through exhausted cards, raises banners and turns defense into retaliation. The Weaver creates Stitches, lays Patterns and gains Tension by alternating card types. Mix their mechanics into your own builds.

The Weaver faces a group of enemies with a charged number board and cards in hand.

Shape your route, face the consequences.

Lay tetrominoes on the act map and choose encounters beside your explored route. Weigh a dangerous fight against a shop, an uncertain event or a moment of rest. Bargains, challenges and rewards can change the direction of your deck. Enemy groups and bosses demand different answers.

A tetromino-shaped route card is ready to be placed on the act map.

Lose, learn, begin again.

Carry what you learn into a new route, unlock more cards and items through play, and take on rising Ascension difficulty. Study your run history, try another hero or follow a combination you overlooked. The next run starts with a new decision.
