Stacks:Space! features a unique combination of base building, card collecting, and rogue action set against a space backdrop. You have to build structures, produce drones and droids, defend your base from enemies and go on interstellar travel, controlled by a variety of cards that can be obtained through purchase, crafting or finds. The gameplay is based on a universal card game framework that allows you to modify and customize your gameplay. By working with JSON files, players can not only introduce new cards, but also create recipes, develop scenarios and create unique locations.

Additional fun comes from Stacks:Village, an additional mod for simulating a fantasy village. There is a variety of scenarios here, each of which has different starting conditions, final goals and various locations. Some scenarios test even the most experienced gamers, requiring careful thought and strategic skill. And the “Daily Challenge” mode introduces an element of unpredictability, setting random tasks and restrictions every day. Combat, a key aspect of Stacks:Space!, features dynamic interactions between ranged and melee modes, pitting players against a variety of enemies and fearsome bosses. Starting a fight is as simple as dragging cards onto an enemy or stacking them together to create powerful crafts. It's worth noting that some opponents may target resource cards, highlighting the need to develop a comprehensive defense strategy.
