Tune a 20-card deck around two heroes.
Pick a pair such as Carter, Queen, Neo, Blue, Lumie, Dracor, or Soccer Boy. Each pairing rewrites your charge economy, summon tempo, and payoff routes.
Lovecraftian deckbuilding card battler
Sealbound
Cthulhu Rising
Build a broken hero deck, enter collapsing world gates, roll through board-game dungeon encounters, and break the math of card battles before the Doom Counter ends the run.
What the game is
Combo discovery inside an apocalypse board game.
Sealbound is a single-player Lovecraftian card battler where the fun target is pride: assemble a machine, push the numbers beyond reason, and feel like you personally cracked the system. World gates give every deck test a larger campaign consequence.
Choose a world gate before doom reaches ten.
The world map tracks collapsed and enraged gates across major cities. Losses raise the Doom Counter; first-time purges pull it back down.
Move around a gate board like a tactical dungeon.
Dice rolls land on battles, treasure, shops, rest tiles, events, elites, and boss encounters. A run becomes a chain of board decisions before the raid.
Let impossible combo math happen on purpose.
The design goal is the moment a player assembles triggers, multipliers, charge, and summons, then watches the board explode upward.
Inside the game
The run moves through five readable command screens.
Lobby
The home screen frames the playable cast and keeps the main routes direct: World Tour, Booster Dungeon, Ranking, Decks, Collection, and Store.
World Map
Gate status, regional threat, boss preview, rewards, and the Doom Counter sit in one readable command surface.
Gate Board
Each gate is a tactical board. Roll the dice and route through battles, shops, events, elites, and the boss tile before the raid.
Battle
Combat uses hero medallions, five minion slots, spell and trap lanes, charge pips, and a hand of cards at the bottom.
Deck Builder
Card collection and active deck tuning share one workspace so you can chase combos without losing the build context.
Heroes and card identity
Cosmic dread on the surface. A playful cast underneath.
Every hero bends the same rules differently.
Carter pays life for burst, Queen bypasses target pressure, Neo raises the charge ceiling, Blue rewards a packed board, Lumie fortifies your slots, Dracor cheats high-level dragons into play, and Soccer Boy can win outright by scoring five goals.
How battles read
Card-game rules stay visible while the board resolves.
- Shared hero HP pool for each side.
- Two hero slots, five minion slots, and five spell/trap/miracle slots.
- Lv1 summons are free; Lv2 has a once-per-turn normal summon; higher levels need tributes.
- Charge rises each turn and powers hero skills and special cards.
- Taunt, stealth, pierce, ranged, blink, traps, and persistent field effects create tactical pressure.
Questions
Everything in one place.
What is Sealbound: Cthulhu Rising?
Sealbound: Cthulhu Rising is a single-player Lovecraftian deckbuilding card battler for PC on Steam (Windows). You pair two heroes, build a 20-card deck, and roll across a board-game dungeon toward a Mythos boss, assembling combos that break the numbers wide open before the Doom Counter hits ten.
Is Sealbound a Lovecraft game?
Yes. Sealbound is set in a 1930s pulp world of cosmic horror, with Mythos bosses such as Nyarlathotep, Ithaqua, and Hastur and a final raid on R'lyeh, wrapped around a deckbuilding card battler. The tone is scary but fun: eldritch dread on the surface, a playful cast of heroes underneath.
What games is Sealbound like?
