Bring Sims Challenges
Into The Game
Install the core framework once, then expand your game with challenge modules that add rules, progression systems, hazards, UI, and entirely new ways to play Sims challenges.
Built for players who want deeper challenge gameplay and creators who want a foundation to build on.
Most Sims challenges exist outside the game.
Written in documents, spreadsheets, and house rules that players must manually enforce. Challenge Mode changes that.
Instead of remembering rules, the game enforces them. Instead of tracking progress manually, the framework tracks it automatically.
Core Framework
The shared runtime that provides systems used by all modules, like UI dashboards, persistence, and rule engines.
Challenge Modules
Installable content packs that plug into the framework to add specific challenge rules, progression, and mechanics.
Creator Support
Developers can build modules using our shared systems, UI components, and documented lifecycle hooks.
