The Simplex Square: A Revolutionary Magic Square

The Simplex Square is an incredibly straightforward and effective Magic Square that I’ve relied on for close-up, walk-around, and casual performances for over a decade. It utilizes a common item you likely have on hand: business cards.

The effect is remarkably simple: a spectator secretly selects and writes down a number. You then take a business card, draw a square, and fill it with numbers. When you ask which column their number belongs to, they will claim it isn’t in any of them. You then invite them to choose one of the four columns, and regardless of their choice, you reveal that it sums up to their chosen number.

But it doesn’t stop there! You demonstrate that all three remaining columns also total their secret number, along with all four rows, both diagonals, the corners, and the four middle numbers. This method requires almost no memorization, and while the handling is straightforward, it remains highly deceptive. The fact that you appear oblivious to the chosen number transforms this from a clever math trick into an astonishing mind-boggler!

I guarantee you’ll master this in just 10 minutes and find yourself using it frequently. It also serves as the PERFECT opportunity to distribute your business card.

If you’re already familiar with a Magic Square, this may not be necessary for you. However, if you’ve been wanting to learn one, struggled with complex formulas, or simply forgot the math, this is the ideal solution!
