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.

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 👌👌

best safety net

This effect is a really good safety net that can be virtually used in any performance, this can effect can be easily added into any routine. the only caveat is that you would need to practice this effect a few times, as there was a time that i once stuffed up the performance.

Cool trick

This is a cool trick and works best on iPhones. Being an Android user, downloading a third party app wasn't the best. Overall, I'm still happy with my purchase and enjoyed the contents from Mark. He explains things well and it was easy to follow.

Mark is a Mental Treasure

The effect is just a solid piece of borrowed from the spectator mentalist to start with, but Mark’s ability to add nuance is second to none. You will be a better performer just from his input.

Face Off

This is an amazing trick which I now use as the final to my close up set. The cards take some time to set up but the effort is so worth it. You don't need anything special to create the gimmicks. It's super quick to learn and really easy to perform. From my experience you should not give the cards out as gifts at the end. Let spectators look at them but take them back. It is possible with the card in hand and time for someone to reverse engineer what has happened. It's so clever and a great buy.
