What if a marking system was so clear a ten-year-old could use it on national television…
and so deceptive it hides in plain sight?
MindBlox by Craig Petty is a modern mind-reading powerhouse built around one of the most ingenious marking systems ever created—designed by Phill Smith and wrapped in the instantly recognizable theme of classic building blocks.
At first glance, it looks like a colorful set of challenge cards. In reality, it’s a precision tool that lets you read words, pictures, and numbers from across the room.
Here’s how it plays:
You introduce the cards as a fun challenge for brick-building fans. One card is sealed in an envelope as a prediction. Additional cards are freely selected, and you demonstrate the difference between reading minds and predicting the future.
You reveal:
- Which card was chosen
- Words the participant is merely thinking of
- The total number of bricks in each set
Then the finale lands.
A final card is selected—and it perfectly matches the prediction that’s been in full view from the very beginning.
The secret is a revolutionary marking system that feeds you information from every square inch of the card while remaining completely invisible to your audience. It’s bold, elegant, and shockingly easy to use.
Craig teaches 10 ready-to-perform routines, giving you instant variety and depth. The cards are so powerful that Ryland Petty used them on America’s Got Talent. The colorful designs and playful theme make the magic feel approachable, while the impact is anything but.
Clear. Deceptive. Devastating.
Read thoughts. Predict the future.
