The Core Design Loop has six steps: inspiring, framing, brainstorming, prototyping, testing, and iterating. Begin with the experience or element that excites you. Put a box around it with constraints, especially a short deadline to the next testable result. Generate ideas, then narrow them into the minimum prototype that can test the central idea or assumption. Show that prototype to someone, gather evidence, and use the learning to cycle through the process again. Justin argues that creative ability is reflected in how well a person moves through each loop and how many useful loops they complete, not in possessing mysterious creative talent.
Origin
Justin developed the six-step loop after entering game design with imposter syndrome and analytically breaking creativity into a repeatable process.
Core principles
- 01Creativity is a process rather than a special trait
- 02Short deadlines turn intent into action
- 03Constraints make a project testable
- 04The smallest prototype should test the central assumption
- 05Creative skill grows through faster, better loops
How to run it
- 1
Inspire
Identify what drives your excitement and the experience you want to create for the audience.
Pro tip Start with a theme, component, mechanic, world, or experience that genuinely energizes you.
- 2
Frame
Put constraints around the project, including a short deadline for the next result and limits on scope or components.
Pro tip Commit to when a prototype will be ready to test.
Watch out Do not begin with a project whose scope requires resources you do not have.
- 3
Brainstorm
Generate many possibilities, organize patterns, and narrow toward the few ideas worth testing.
Pro tip Keep idea generation separate from criticism at first.
- 4
Prototype
Build the smallest and easiest artifact that can test the idea or its core assumption.
Pro tip Reuse cards, dice, paper, or existing objects before creating polished assets.
Watch out Early polish creates sunk cost and resistance to change.
- 5
Test
Show the prototype to someone and observe what actually happens.
Pro tip Know the question the test is meant to answer.
- 6
Iterate
Apply the learning, then cycle back through the loop with a more specific question.
Pro tip Move from large foundational questions toward smaller polish questions over successive loops.
Watch out Do not treat one successful test as a finished product.
In the wild
Tim maps the process to a podcast: choose the motivating theme and format, constrain production so it can continue, brainstorm guests and questions, record several episodes before publishing, test with guests and listeners, and iterate.
→ A broad creative ambition becomes a sequence of testable decisions.
Justin's first Ascension prototype shuffled together cards from Dominion and changed how they entered play. The result was not good, but it tested whether the randomized structure contained something fun.
→ The rough test supplied enough proof of concept to continue.
Common mistakes
Starting with an enormous scope
A first-time designer cannot test effectively by combining several massive games into one project.
Polishing before finding the fun
Investing in presentation before the foundation is proven wastes time and makes changes emotionally harder.
Skipping the external test
An idea remains an assumption until someone actually interacts with the prototype.
Is it for you?
Best for
Designers, founders, writers, and other creators moving an uncertain concept toward a working result.
Not ideal for
Projects whose solution and execution path are already fully specified and validated.
From the transcript
“So the core design loop is six steps. It's inspiring, framing, brainstorming, prototyping, testing, and iterating.”
“What's the smallest thing I can do to test my idea?”
“And what I've learned is that the skill of creativity, specifically with game design, but really with anything is how well you can kind of…”
