You Know (UNO) by David Jonathan

You Know is a powerful display of foresight that is so direct, so fair and so utterly baffling. It uses an ancient, underused principle that has been dusted off and modernized with new twists to create a stunning hands-off prediction.

So what's the effect? A pack of UNO cards is introduced and a participant names any of the four colors in the game to be their target color. They take the cards and genuinely shuffle them into a truly random order. They now look through the shuffled pack and remove the first three cards of their target color that they come to. The numbers on these cards are added together to arrive at a sum. An envelope, that has been on the table, is turned over to show one number was written on it - the sum of the three numbers! Even more impressive, inside the envelope is a prediction of the SPECIFIC COLOR they named and the EXACT THREE NUMBERS they arrived at!

• Ends clean
• No gimmicks
• No sleight of hand
• Super easy to do

Tons of extra ideas and variations are covered on the tutorial, as well as ways to incorporate the concepts into a variety of routines (e.g. book tests, pin code revelations, etc.).

You Know provides an engaging change of pace from run-of-the-mill card tricks, so download it today to learn one of the strongest effects with a pack of UNO cards!

Note: While this effect was designed for UNO cards, it is also easily adapted to playing cards

"David Jonathan is a very creative magician. I never knew you could have such a strong magical effect with a deck of Uno cards." 
- Chinese Magic Reviews

"A great cross between mentalism and a multiple prediction card effect... it has a nice hook and the principle is clever and fooling. I give it a solid 5/5."
