A game with 3 predictions and a bet.
Two of the predictions are written behind 2 cards and the third prediction is a card that is between two bills (by way of prediction), the magician shows a deck of cards facing up that is of another color of back with respect to the prediction. Invite the spectator to name a card (for example 2 diamonds), which is removed from the deck and left next to the prediction.
When reading the first card it will say: It will be a red card, the second prediction will say: It will not be a figure, (confirming in this way the second success) and when turning the prediction card that is between the bills it will be seen that it coincides exactly with the chosen letter.
An extremely direct effect with 100% effectiveness.
