EDC Squared XL (Single Fold) by Mark Traversoni

Let a spectator name a two-digit number, then reveal it as the total across the rows, columns, and diagonals of a 4 × 4 Magic Square. EDC Squared XL by Mark Traversoni brings this classic effect to an A4-size display, so it’s easier for a larger audience to see.

The Astrology Card design gives you a polished presentation for close-up or group performances. After the reveal, you can give a card away as a keepsake or wipe it clean for reuse.

• A4 single-fold size: Each card measures 210 × 297 mm (8.27 × 11.69 inches) and folds in half to approximately 148 × 210 mm (5.8 × 8.3 inches).
• Six different layouts: The simple crib lets you repeat the effect for the same audience up to six times, with a different-looking grid each time.
• No memory work: The layouts are printed in plain sight, making the routine easy to learn without complex math.
• Reusable cards: Dry-erase and Sharpie ink can be wiped off, so you can perform again with the same cards.
• 20 cards and expert teaching: The pack includes 20 Magic Square cards in the selected version, with teaching from Mark Traversoni. Number Peek and No Peek versions are available.

Use the cards for a striking prediction-style moment, then leave your audience with a souvenir they can keep. The large folded format also makes the reveal easy to share in a parlor or group setting.
