Entropy Hack by Tommaso Guglielmi

This powerful web app brings a timeless card magic classic into the modern age. Inspired by Charles Jordan’s method, it allows you to identify a selected card after genuine shuffling and multiple cuts – even using overhand shuffles.

No sleights. No peeks. The spectator handles the deck from start to finish, while you never touch the cards – not even once.

Whether you’re performing in person or remotely, this tool gives you full control with near-perfect accuracy. Built for working magicians, designed for real-world conditions. Repeatable. Reliable. Undetectable.
