The flow

1. Luke goes first. He'll work through some cards on the big screen, talking out loud. Everyone watches and chips in with ideas.
2. Then each of you grabs your own laptop. Type your name. Think about which game you want to design.
3. Tap Draw card. Read the question. Use the little hint underneath if you're stuck for ideas. Type your answer. Hit Save & next card.
4. Stop whenever you've got enough — five or six cards is plenty.
5. When time's up, tap Review answers. We'll go round the room — each person shows their summary, and the others get to challenge them: "What about…?" "Have you thought about…?" Edit your answers live as you go.

The four phases

The cards come in a deliberate order — first imagining, then defining, then narrowing, then poking holes. Within each phase the order is random, but you'll always finish one phase before moving to the next.

1. BLUE SKY — opens your imagination. What's possible? What's weird? What's exciting?
2. DEFINITION — pins down what your game actually is. What can the player do? How do they lose?
3. CONSTRAINT — narrows you to the smallest version you can actually build.
4. STRESS TEST — finds the holes. What breaks? What hasn't been thought through?

If you get stuck

• It's OK to say "I don't know yet." Type that and move on.
• The little hint on each card is a starter — but your answer doesn't have to be one of those.
• You can switch between Drawing and Review at any time.
