Hi been shown a card trick today and realy want to get to the bottom of it .
A Deck is shuffled and then you are asked to say stop at any point , he places a card from the top onto the table u can stop at 1 or after 20 etc up to you. he then picks them up and puts them back into the pack splits the pack into 4 quaters and leaves about 5-10 cards seperate in which he puts 1 more onto the top of each pile. he then gives you the top card of the card which is left and tells you to put it back into a pile anywhere , he then shuffles and lays the cards back on the table and is able to find it. completely stumped any help pretty please lol.
