Identify cards by relative order

Video in production

This lecture is still face down. Its script is written; filming and animation are under way.

What you will learn

Perform and justify a six-card relative-order revelation from highest and lowest positions.

The trick in this lecture Gold & Silver Point out the highest and the lowest of three cards, and all three are named. Play the trick

Ideas you will use

  • Cyclic cuts and fixed observation order
  • Ace valued as one

In this lecture

An outline of the lecture, scene by scene, with the statements that appear on screen. It follows the draft script, so details may change in production.

  1. Establish six-card relative-order performance

    At the table
    • Ace=1
    • Keep selection order 1–3
    • Report highest and lowest places

  2. Decode roles and reveal without direct identities

    At the table
    • Highest/middle/lowest pattern
    • Exact identities follow from prepared positions

  3. Second reveal and credit precise teaching adaptation

    At the table
    • Rank cycle 1,4,6,2,5,3
    • Prepared packet; fixed direction
    • Relative order locates the window

  4. Enumerate six relative orders

    • 3×2×1=6 patterns
    • Roles depend on the window
    • Count does not guarantee a valid cycle

  5. Verify exact six-cycle and lookup

    • 146→LMH
    • 462→MHL
    • 625→HLM; 253→LHM; 531→HML; 314→MLH

  6. Explain legal freedoms and direction sensitivity

    • Any cyclic start
    • Consecutive selection only
    • Direction and identity assignment fixed

  7. Teach practical protocol and full lookup

    • Preparation: AC,4D,6H,2H,5C,3S
    • Highest 1, lowest 2→HLM
    • Highest 3, lowest 2→MLH

  8. Companion and next abstraction

    • Goal: all 6 relative patterns
    • HML→5C,3S, AC
    • Next: universal cycles

Companion interactive

Decode exact triples from relative roles and build a collision-free six-rank cycle.

The trick page is this lecture’s companion: be the spectator, lift the curtain to step through why it works, try the challenge, then learn the handling.
