Eu Duvido!
Bluffing trivia party game: bid a number or call EU DUVIDO!
A Brazilian party game for iPhone (in Portuguese). Each round asks a question with a number answer nobody knows, like how many km of blood vessels are in your body. Players bid "that or more"; the next one raises or shouts EU DUVIDO! (I doubt it!). Then the answer is revealed and someone loses a life. 2 to 8 players on one phone passed around, or each on their own phone with a room PIN. 700+ hand-picked questions with sources.
Hey Product Hunt! 👋
I'm Giuseppe, a solo dev from Brazil. Eu Duvido! means "I doubt it!": it's a bluffing game where every question has a number answer that sounds like a lie. You don't need to know the answer, you need to bluff better than your friends and doubt at the right time.
Some things I learned building it:
• A good question is one where people are sure they know and miss by 100x. I threw away 109 of my first 708 questions.
• Party games spread in groups, so you can play on a single phone or create a room with a PIN.
• Built with Expo, Supabase (realtime rooms) and RevenueCat.
It's in Portuguese for now. If you have Brazilian friends, I'd love for you to try it at your next hangout and tell me which question started the biggest fight. 😄
