Constraint Engine

Constraint Engine

A focused ideation tool for solo developers, game jam players, hobbyists, and creative thinkers who work best with limitations, prompts, and direction.

Instead of endlessly brainstorming, Constraint Engine pushes you toward ideas you can actually build.

What Is It?

The engine combines themes, mechanics, genres, twists, moods, and development constraints into focused prototype ideas.

Then, once you find something worth exploring, the app helps you converge on a playable concept through a guided development flow.

Core Features

Idea Generation

Generate ideas using:

- Game jam themes

- Genres and subgenres

- Mechanics

- Settings and themes

- Constraints

- Twists

- Core feelings

- Timeline targets

- Development focus prompts

Customise exactly which pools are used and lock specific prompts into generation.

Draft Mode

Generate ideas through a drafting flow where you choose between multiple generated options step-by-step instead of relying entirely on randomness.

Convergence Flow

Every saved idea includes a guided convergence system built around 7 structured questions designed to push vague concepts toward something prototype-ready.

The goal is not just to generate ideas — but to help answer:

- What is the actual core loop?

- What makes this interesting?

- What is the smallest playable version?

- What could kill the idea?

- What should be built first?

Save and Organise Ideas

- Save generated ideas
