Read the full description

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.
