Numeromantia

A number-field deckbuilder

Numeromantia is a single-player deckbuilding roguelike for PC, set at an alchemist’s table where a shifting field of numbers fuels your cards. You place cards in particular areas of the field, then turn the numbers there into attacks, shields, or prepared cell effects. Each play changes the puzzle formed by your hand and the field.

A strong line of numbers might deal damage now or be saved for defense. Some effects consume cells, which need time to recover before they can power the strongest cards again. Enemies show their intentions, but groups of opponents make it important to choose targets, and rising pressure can make holding back dangerous.
