Constraint Engine

Constraint Engine

A focused ideation tool that turns scattered ideas into something you can actually build. 

Generate constrained game concepts from themes, mechanics, and twists — then shape them into a clear, prototype-ready direction with a simple guided flow.

Save ideas, develop them over time, and export everything when you’re ready to build.

Runs entirely in your browser. No setup, no accounts.
