The Magician’s Code: Calculating the Si Stebbins Position

The Si Stebbins stack is built on a simple, consistent cycle, meaning the distance between any two cards in the deck can be found with basic arithmetic. This method breaks the calculation into three simple steps that are easy to perform in your head.

The goal is to find the Final Position from the Top (1-52) for the Target Card, assuming the Bottom Card is at position 52.

(Note: I have a Si Stebbins Trainer page to help you practice this method. It is at http://robertjwallace.com/stebbins)

Stack Reveal Helper: A Web-Based Card Magic Companion


I’ve used AI to create a tool for card magicians who work with deck stacks. This web application was inspired by Lloyd Barnes’s MAXIM app, which unfortunately kept crashing on my device. Rather than wait for fixes, I decided to create my own web-based alternative that captures the core functionality while adding some unique features.

The Last Trick of Dr. Daley extended.

While teaching a student the Elmsley count as a setup for “The Last Trick of Dr. Daley,” I made an interesting mathematical observation. Starting with the four aces in Black, Black, Red, Red order (face down), the Elmsley count creates a predictable cycle:

  • First count: B,B,R,R → B,R,B,R
  • Second count: B,R,B,R → B,R,R,B
  • Third count: B,R,R,B → B,B,R,R (back to start)

This three-count cycle became the foundation for a routine that provides for a two phase Daley effect.
