  • that's fantastic!! I figured out how to do the trick in italian!! next step: french russian and german xD

  • @nik8090 Great (I'm interested if you want to send it)

  • i have a question!

    when you do the trick,

    do you tell the person to "say whatever card he/she wants to say?"or"tell me the card you choose?"

  • I explain: "In a minute I will ask what your card was - but, I'm going to give you the chance to lie. So you could name any card that you want! Ok? What was you card?"

  • @LolZiizLeR1337 Then.... you could say... "hey, you told the truth?" Sorry, a bit of a dumb question.

  • @nik8090 how can i make to figure it out in spanish and german? PLS pm me :)

  • consider my mind blown

  • interesting!!

  • @nik8090 Già. In italiano si può fare tranquillamente, funziona lo stesso perché anche in italiano non esiste una carta che abbia meno di 3 lettere e non esiste un seme con meno di 5 lettere ;)

  • Thanks:)

  • cant you just look 3 cards down?

  • Permutation group on 9 letters

  • what happens if the person says the same card they chose

  • You would be the best teacher!
