Imagine a spectator freely choosing a unique 4-digit PIN.

The magic of Checksum enables you to read their mind and reveal that number every time.

Checksum requires no magic apps, no complicated forces, and utilizes the spectator’s borrowed phone.

Built on a remarkably simple mathematical principle, if you can calculate 6-3 = 3 in your head, you can perform this effect.

Here’s the clever twist: once you disclose their chosen PIN, you’ll also uncover their exact date of birth without them realizing how you did it.

This opens the door to birthday reveals, star sign predictions, one-ahead routines, and much more.

• Checksum is not reliant on toxic forces.
• No custom magic apps are needed.
• It can be executed using their phone.
• It’s so straightforward that anyone can master it.

With Checksum, you’ll always be prepared to perform. Even if you prefer using magic apps, knowing Checksum provides a reliable backup in case of technical issues.

Note: Checksum utilizes a scientific calculator that is standard on some Android devices. If yours doesn’t have one, you can download a free app from the Play Store, but it won’t be borrowable. iOS users are in luck; it works seamlessly on all Apple devices.
