  1. Narrator: From Spark and Anvil and TableForge — this is Sprawl, in chapter 1 of the TableForge cast.
  2. Narrator: This drama uses an AI-generated voice. Voiced via Gemini 2.5.
  3. Narrator: Sprawl designs the deep, satisfying kind of game — the sort where your early moves quietly power up your later ones. Sprawl calls it building an engine.
  4. Sprawl: The best feeling in a game is when one piece helps the next, which helps the next. You set something up, and three turns later it's paying off in a chain you built yourself. That's an engine — and a good engine grows itself. Each part makes the other parts stronger.
  5. Narrator: An engine — pieces that feed each other, so your plan snowballs.
  6. Sprawl: I design pieces that COMBINE. This card gives you coins; that one turns coins into gears; a third turns gears into points. Alone, each is small. Together, they form a machine YOU assembled. The joy isn't any single piece — it's watching the whole thing click into motion.
  7. Narrator: Sprawl once made a game where every piece stood totally alone.
  8. Sprawl: Each card did its own thing and never talked to the others. Players just picked the biggest number each turn. It was fine — and completely forgettable. There was nothing to BUILD, no combo to discover, no "aha, if I get this AND that..." Just a pile of separate little actions.
  9. Narrator: So now Sprawl designs for connection.
  10. Sprawl: For each piece I ask: what does this make BETTER? If the answer is "nothing," it's an island, and islands are boring. When pieces feed each other, players stop picking the biggest number and start dreaming up combos. That's when a game gets deep.
  11. Narrator: A designer's cards each did their own isolated thing.
  12. Sprawl: See how no card cares about any other card? Make this one BOOST that one. Now a player who grabs both feels clever — they built a little machine. Suddenly they're planning three turns ahead instead of just grabbing.
  13. Narrator: The designer linked the pieces, and playtesters started gasping "wait, if I combine these—" and scheming turns in advance.
  14. Sprawl: One piece that helps the next, that helps the next. Let your pieces feed each other, and the engine grows itself.
  15. Narrator: You've been listening to a Spark and Anvil chapter, written by the Spark and Anvil writing team for ages 9 to 14.
  16. Narrator: Apps stay free forever.
  17. Narrator: Curriculum aligned to Common Core and Next Generation Science Standards.
