Key Takeaways

  • Daichi Hiruma’s LIVE 404 took first place with a cinematic horror game whose audience comments guide a streamer through AI-generated haunted locations.
  • autoV placed second, MAKE THEM FALL (in love) placed third, and Little Makers received the audience prize.
  • The challenge drew 45 teams, with 11 finalists presenting working demos at the September 17 showcase.

What Happened

Tokyo AI’s official event recap named Daichi Hiruma’s LIVE 404 the grand-prize winner of the 100-Hour Game Builder Challenge. The project is a cinematic horror game in which viewer comments guide a streamer through haunted locations while AI generates video in real time.

Second place went to autoV from Taiki Kawa, Rahul Ghosh and Eric Volkmann, a tool that turns images and prompts into editable real-time visual effects. Jun Misaki and Shunya Abe’s MAKE THEM FALL (in love), a multiplayer dating game whose audience votes determine the next AI-generated scene, placed third.

Little Makers by Aleksandr Drozd won the audience prize with a browser-based Python game workshop guided by an AI companion. Organizers said 45 teams participated and 11 finalists presented, although the official recap did not identify every finalist.

Why It Matters

For game creators, the strongest signal is the range of uses on display: generative video inside play, editable effects for production, audience-directed narrative and AI-assisted learning. The winners show AI being tested as part of the game loop and the development workflow, rather than treated as a standalone novelty.

What’s Next

Tokyo AI says finalist videos will follow. Those demos should make it easier to judge how well the projects play, how reliably their AI systems perform and which ideas can grow beyond a 100-hour prototype.
