​Most people only play Voodoo games. This weekend, you build them.

​​April 25–26, 2026 | Paris

​​From Saturday morning to Sunday afternoon, you'll work inside Voodoo's Paris HQ with direct access to their team. Not as judges watching from a distance, but as mentors in the room, figuring things out together. Organized by Unaite in partnership with Anthropic and Voodoo.

30 hours to see how far AI can take you, alongside future teammates, co-founders, or just people who geek out about the same things as you.

​​🏆 Prizes & Perks

• ​​€4,500 cash prize

• ​​Unlimited access to Anthropic's latest AI models

• ​​AI-generated art credits on Scenario

• ​​A dedicated Voodoo mentor by your side for the whole 30 hours

​​⏰ The Sprint

​​Kick-off Saturday April 25 at 10:00 AM. Final submissions Sunday April 26 between 2:30 and 4:00 PM. Come as a team of 3 — and leave with something people can actually play in their browser.

​​📒 Logistics

​​Full catering provided (breakfast, lunch & dinner). The venue is open 24/7 — build through the night if that's what it takes.
