Hey gang. I used to do a card trick which had 5 piled of cards all equal amounts. The hard part comes when you add an ace into the mix and request someone to move whichever cards they want but the piles have to go back to the original values. Not removing any cards. Adding aces is repeated one at a time Once the equationn is complete u till all 4 aces are in the mix. Now from memory the number in the piles was 5x piles of five. So four corners with a 2 and 3 in each corner 2+3=5... And just a number 5 card in the middle... Hence 5 piles of 5. Add an ace onto the 5 in the middle and request someone rearrange them to give you 5 piles of five again. Is this correct and if so how does it work? I definitely remember doing this trick but can't remember if it was piles of 5 and if it was. I don't remember what cards to move to which locations... Thanks for your help..
