Algorithm (App) by Yves Doumergue

A multi-phase act in your pocket. Transform a phone into your secret weapon with "Algorithm" by Yves Doumergue. Predict the location and order of the cards in a deck with 100% accuracy. Don't be surprised if you get a few invites to Vegas after performing this. Imagine the following: The audience shuffles a deck and pulls out any five cards at random. You load up The Algorithm on a borrowed smartphone. The spectator enters any four of the chosen cards into The Algorithm. The Algorithm processes the data and reveals the unknown card... with 100% accuracy. That's interesting enough on its own, but to really demolish the critics, you're gonna need to do it again. So, you do.But this time, you up the odds: The audience chooses any four cards this time. The spectator enters any three of the chosen cards into The Algorithm. The Algorithm processes the data and reveals the unknown card... with 100% accuracy. But it doesn't end there. You repeat the feat yet again, with just three cards.
