Algorithm - Physical Copy (App) by Yves Doumergue

Turn a shuffled deck into a rising sequence of impossible card revelations with The Algorithm by Yves Doumergue. A spectator enters cards from their selections into the app, and it reveals the card they kept hidden. The routine builds to a prediction of the location and order of every card in the deck.

Use your own deck and a smartphone—yours or a spectator’s. The four-phase act moves from revealing one unknown card among five, to revealing one among four, then one among three, before the full-deck prediction.

• Progressive revelations: The spectator enters four of five chosen cards, then three of four, then two of three, as the app reveals the remaining card each time.
• Full-deck finale: End by predicting the location and order of every card in the deck.
• Phone-friendly setup: The routine is self-contained and can be used on your phone or a spectator’s smartphone, even when they are a time zone away.
• Use your own deck: The Algorithm does the heavy lifting without gaffs or gimmicks.
• Learn and rehearse: A tutorial library includes written instructions and videos, while a training simulator lets you practice the key steps.
• Flexible instruction: Yves Doumergue and Gregory Wilson teach the routine, including Gregory’s personal approach for performing without the app. Customize the layout, setup, auto-advance timer, and suit order.

The sequence gives you a card-magic presentation that grows more astonishing with each phase. Use the app’s training simulator to rehearse before bringing the routine to your next performance.
