The Birthday: Guess the spectator's birthday with cards!? 【Effect】 First, ask the spectator how many digits are in their birthday. Let's say their birthday is December 24th, and they answer 4 digits. Next, spread a deck of cards face down and have the spectator touch one card. Give them the remaining three cards nearby as well. When the spectator turns over the four selected cards, they perfectly match the spectator's birthday!! This is the perfect trick for birthday celebrations and events! Recommended as it can be enjoyed by children and adults alike! 【Contents】 Special gimmick, Sunday instruction manual *Please tell us the birthday you want to guess in the comments before purchasing.
