Lie Detector Trick by Tony Griffith

Effect

The Lie Detector Trick is a psychological card routine where the magician demonstrates an uncanny ability to detect lies. A spectator selects a card from a shuffled deck and lies about its identity. Despite the deception, the magician correctly identifies the chosen card every time. The effect plays on the idea that the cards themselves act as a lie detector, revealing the truth no matter how hard the spectator tries to mislead.

Full Details

This trick is designed for shuffled-deck conditions, meaning no prearrangement is needed. The spectator freely selects a card, memorizes it, and returns it to the deck. The magician then asks the spectator to lie about the card's value and suit while dealing cards based on the letters in their false statements. Despite the spectator's attempts to deceive, the magician reveals the correct card with precision.

The method is self-working, relying on a clever principle rather than complex sleight of hand. The routine is structured so that every possible lie leads to the same outcome, making it foolproof in performance.

Who Should Consider the Trick

This trick is ideal for:

• Walk-around performers who need quick, interactive routines.
• Mentalists looking for a card-based lie detection plot.
• Bar magicians who want a strong, engaging effect with minimal setup.
• Beginners seeking a reliable trick that doesn’t require advanced sleights.

Difficulty

The Lie Detector Trick is easy to perform, making it accessible to magicians of all skill levels. The method is based on a logical principle rather than difficult moves, so even those new to card magic can master it quickly.

What Magicians Say

Daniel Chard, a professional magician who performs weekly at Smoke and Mirrors in Bristol, praises the trick for its fairness and audience interaction. He says, "It's one of those tricks where even if you get a heckler who tries to mess you up, it's going to work. It's bulletproof—nothing can go wrong."

Tony Griffith, the creator of the trick, has shared it in lectures worldwide, and magicians appreciate its real-world practicality. Unlike many lie detector plots that require special cards, this version works with any shuffled deck, making it a versatile addition to any set.

The trick is also noted for its psychological impact, as it plays with the idea of deception and truth in a way that feels organic and engaging for spectators.

If you're looking for a strong, interactive card trick that requires no setup and plays big, the Lie Detector Trick is a solid choice.
