EDC Squared XL (Pocket Fold) by Mark Traversoni

Give your audience a Magic Square that feels like a remarkable coincidence: they name a two-digit number, and the rows, columns, and diagonals of a 4 × 4 grid add up to it. EDC Squared XL by Mark Traversoni brings the effect to a larger A4 format, with the Pocket Fold version folding down to fit inside a jacket pocket.

Use it for a close-up presentation or display it for a larger audience. After the reveal, the card can become a memorable souvenir—or be wiped clean for another performance.

• Pocket Fold size: Each card starts at 210 × 297 mm (8.27 × 11.69 inches) and folds to approximately 75 × 210 mm (3 × 8.2 inches).
• 20 cards: The pack includes 20 Magic Square cards in the version you select.
• Repeatable effect: Perform it for the same audience up to six times, with a different-looking grid each time.
• Easy to learn: The routine is designed without memory work or complex math.
• Reusable cards: Dry-erase and Sharpie ink can be wiped off, so you can use the cards again.
• Version choices: Number Peek and No Peek versions are available; a single-fold A4 version is also offered.

Mark Traversoni provides expert teaching to help you learn the routine. Finish by giving away a filled-in card as a keepsake from an impossible-feeling moment.
