Infinite Cards

Most deckbuilders hand you a fixed card pool and ask you to draft smarter than your last run. Infinite Cards, developed by Tubby Turtle Studios, discards that premise entirely: every card in the game is procedurally generated from a rule set, meaning no two cards are guaranteed to appear the same way twice across any number of runs. The practical result is that synergy-hunting becomes an act of genuine discovery rather than pattern recognition from a memorized catalog.

Each run is structured around a commander chosen at the start, one of more than twenty options, each with distinct abilities that push the player toward a different strategic posture. Progress through seven locations with their own enemy rosters and bosses, spread across five difficulty tiers, and card rewards grow stronger the deeper a run goes, so the deck keeps shifting in power and character until the final encounter. Ten-plus factions are available, including humans, dragons, and skeletons, and cards can be found, purchased, crafted, or upgraded during a run. The deck itself is fully open: cards can be added or removed at any point, with no lock-in enforced mid-run.

Combat resolves around layering units, relics, and spells in combinations that compound one another. Because the cards themselves are not fixed quantities, identifying and exploiting synergies requires reading each new card on its own terms rather than slotting it into a known build. Optional modifiers can be switched on for players who want additional pressure beyond the standard difficulty tiers. A separate puzzle mode strips away the run structure and presents preset battlefields that must be resolved in a limited number of turns, functioning as a focused laboratory for testing interactions.

A demo launched in January 2026 ahead of the March 27, 2026 release. The first weeks after launch produced several rapid patches through April. May 2026 brought what Tubby Turtle Studios labeled a giant update alongside a further patch, and maintenance patches continued into June 2026, suggesting active post-launch support through at least the first quarter after release.

The closest genre comparison is Slay the Spire, though Infinite Cards trades that game’s curated, hand-balanced card pool for procedural generation and fully unrestricted deck composition.
