Mind Blocks by Craig Petty

Effect

Mind Blocks is a Lego-themed mentalism trick that uses a specially designed deck of cards. The cards feature images of different Lego sets, complete with difficulty ratings, piece counts, and other details. The magician can predict a spectator’s chosen Lego set, reveal hidden information, or perform mind-reading effects—all while making the experience fun and engaging, especially for younger audiences.

Full details

Mind Blocks is a marked deck where each card’s back contains hidden information about the Lego set displayed on the front. The marking system is designed to be easy to read, allowing the magician to identify the set, piece count, and other details at a glance. The deck includes multiple routines, such as:

• Prediction effects: A spectator freely selects a Lego set, and the magician reveals a matching prediction.
• Mentalism routines: The magician deduces information about the chosen set without any apparent clues.
• Combination with other tricks: Mind Blocks can be integrated with other props, such as toy catalogs (like Craig Petty’s Toys), for expanded routines.

The deck is visually appealing, with bright, colorful Lego designs that make it engaging for audiences, particularly children.

Who should consider the trick

• Family entertainers: The Lego theme makes it ideal for kid-friendly shows.
• Mentalists: The marked deck allows for strong mind-reading effects.
• Close-up performers: The compact size and versatility make it great for walkaround or table-hopping.
• Magicians who enjoy visual props: The Lego theme adds a playful, interactive element.

Information on how difficult it is to perform

Mind Blocks is designed to be accessible:

• Beginner-friendly: The marking system is straightforward, and many routines are self-working.
• No advanced sleight of hand required: Most effects rely on the deck’s design rather than complex techniques.
• Practice needed for smooth performance: While the mechanics are simple, presenting the trick naturally and engagingly requires rehearsal.
