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?

“Numeromantia combines deckbuilding with a grid of numbers and cell effects. We want to refine that interaction with players: which builds reward planning, where encounters become repetitive, and how clearly the game explains a card before it is played. Early Access will help us improve balance, usability, and presentation through feedback from real runs.”

Approximately how long will this game be in Early Access?

“We currently expect Early Access to last approximately three months. This is an estimate: the schedule may change depending on player feedback and the work needed for version 1.0.”

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

“For the full version, we plan to refine the balance of the characters and their build options, improve encounter and reward variety, and continue polishing combat feedback, animation, sound, and interface clarity. We also plan to improve localization and address issues reported during Early Access. The exact scope may evolve with player feedback.”

What is the current state of the Early Access version?

“The current version supports complete runs through the campaign with distinct playable characters and Ascension difficulty levels. It includes character-specific cards, artifacts, potions, branching routes, events, battles against multiple enemies, a searchable glossary, and run statistics. The core run is playable from start to finish. Balance, presentation, and localization are still being refined, and bugs may occur.”

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?

“We plan to use Steam discussions and player reports to collect feedback on builds, enemy encounters, difficulty, interface clarity, and bugs. Run details and examples of unexpected card interactions will be especially useful. We intend to share development updates and explain significant balance changes as we work toward version 1.0.”

About This Game

Build your deck. Shape your battlefield.

At a candlelit alchemist's table, a field of numbers holds the power of your next move. Numeromantia is a single-player deckbuilding roguelike where cards draw strength from a changing field. Turn its numbers into attacks and shields, prepare powerful cell effects, and choose the moment to consume them.

Every placement is a decision


Each card works with a particular area of the field. Spend a strong line on damage, preserve it for defense, or use another card to prepare a better turn. Consumed cells must recover before they can fuel your strongest effects again. Your hand and your field are a single puzzle, changing with every play.
Enemies reveal their intentions. Groups of opponents make target selection matter, and mounting pressure makes waiting forever a dangerous plan.

Distinct heroes. Different ways to change the rules.

  • The Alchemist charges cells with elements, transforms metals, brews potions and turns preparation into powerful discharges.
  • The Oathkeeper burns cards for resolve, raises protective banners and turns a well-timed defense into a counterattack.
  • The Weaver creates temporary stitches, lays patterns across the field and builds momentum by alternating card types.
Each hero has a distinct card pool and interconnected build paths. Combine their mechanics with upgrades, artifacts and potions to find your own way through.

Shape the journey as well as the fight

Place route shapes on the act map and choose the encounters you will face. Weigh an elite battle against a safer path, spend your gold carefully, and decide what a mysterious offer is worth. Changing maps, events and rewards give each run a different set of decisions.

A small field with room to master

  • Heroes with distinct card pools, upgrades and temporary cards.
  • A journey through acts filled with ordinary encounters, elites and bosses.
  • Artifacts and potions to support and reshape your build.
  • Ascension levels that add new challenges beyond the base difficulty.
  • A searchable glossary and detailed run history to study your choices.
Settle in among walnut, brass, glass and parchment. Your next great combination is waiting on the table.
