"You can press only one button. Which one?"
"If you could eat it forever, which one?"
"Which world would you live in for life?"
Which One? is a game of impossible either/or questions, each one shown with a beautiful AI-generated video.
It looks easy. You won't be able to choose. That's the whole game.
■ See the world's answer instantly
Are you in the majority or the minority? Real-time voting from players worldwide reveals "what % chose this" the moment you tap.
Pick a path chosen by 30% or fewer and earn a rare minority card!
■ Collect the worlds you chose
Every choice becomes a card in your collection, sorted by series. Tap a card to replay its video anytime, and peek at the other world too.
