Hell Builder

Hell Builder is a building puzzle in which you act as the Dark Lord’s chosen architect. Using building cards, careful placement and resource management, you construct every structure on a list to complete each Dark Lord’s vision.

Place buildings and build synergies

Each placement matters. Structures can create synergies that generate Souls, your primary currency; poor placement can leave you short of resources, while chains of synergies keep your construction going. Buildings also unlock according to their surroundings: Spider Queens, for example, appear only next to Spider Nests.

Turn runs into progress

If you run out of Souls, you can use Transmute Hell to convert your entire domain into relics, then start again with new advantages. The larger your previous hell, the rarer and more powerful the relics you can choose. This prestige system lets each run contribute to your progress.

Dark Lords and content

The game has approximately 5–10 hours of content across five Dark Lords. Each has a different building list to complete and a unique playstyle. Runs take about 30 minutes, and the game uses pixel art with a limited color palette.

Key features

• Synergy-driven building puzzles, where every structure must earn its place
• Buildings that unlock based on adjacency
• Transmute Hell, which turns a run into permanent progression
