Three Clues ACAAN By Miku W

A spectator freely selects a card, returns it to the deck, and the deck is shuffled. The magician then asks the spectator to name a small number and deals three packets of that number of cards. The selection is not found. However, adding the values of the three dealt cards not only locates the selection, but also reveals the other three cards of the same value.

For the complete routine, please watch the video demonstration.
