A SUREFIRE PIN REVEAL WITH A SNEAKY SECRET


Someone creates a unique 4 digit pin. Free choice.

The secret behind Checksum allows you to read their mind and know that number, every. Single. Time.

Checksum uses no magic apps, no toxic force, and the spectator's borrowed phone.

It's based on a stupidly simple math principle that anyone can do. If you can do this in your head... 6-3 = 3, you can do this effect.

Here's the sneaky bit. After you reveal their freely thought-of PIN, you'll secretly know their exact date of birth. They'll have no idea how you got it.

Now you can do birthday reveals, star sign reveals, one-ahead routines, and much much more.

  • Checksum is not the toxic force.
  • It uses no custom magic apps.
  • It can be done on their phone.
  • ... and it's so simple even a chimp can do it

With Checksum, you'll always be ready to perform - and even if you like using magic apps, knowing Checksum will give you an iron-clad backup should they ever fail.

Checksum by Mark Lemon is an unexplored, borrowed-phone phenomenon that you can learn INSTANTLY.

p.s. Checksum uses a scientific calculator that only comes standard on some Android devices. If you don't have one, you can download one for free from the Play Store, but then it can't be borrowed. Using iOS? You're all good. It'll work on every Apple device.

Mark Lemmon at it again with his creativity. This is one of the more mentally difficult effects straight out of the gates but with practice it destroys spectators.

Checksum is clever

When I first purchased this trick, I found the math a little daunting. I know other clever ways of getting a birthday or a predicted sum but this has both. This routine has a clever structure to it and flows very well that you can add your own mentalism style.

Cheapest way to impress

There is learning course you have to make so its not eazy trick that works it self, also i think im important to mention pin code is not like pin code of phone or credit card, its pin-code of calculation. Once you get chill with around 3-4 days you can make this trick anywhere. And i suggesting to use your phone because its easyer.

Anyway its good for audience and i perform it already 12 times and went all good 👌👌
