Flexible Choice

This effect is a straight card location, where a chosen card is found at a number "freely" created by a spectator.

This uses George Sands' "One to Eight" principle.

Set the following eight cards (disregard suits) on top of the deck:

Finally crimp the corner of the twenty-fifth card from the face.

WORKING

1. Give the deck any shuffle that retains the top stock (i.e., down through and including the crimped card), then give it a cut, taking the crimp to the bottom, and hold a break between the halves.

2. Invite a spectator to participate. Riffle down the outer left corner and ask him to call stop. When he does, lift off all the cards above the break (Riffle Force) and give him the lower half. Place the remaining half facedown on the table.

3. Tell him to deal his top card face-down on the table then to deal another card face-up on top of it to create a back to back pair. He now creates three more similar pairs forming a row of four back-to-back pairs (Fig.1 - next page).

Ask him to shuffle his remaining cards, look at the face card and remember it, then drop the packet square on top of the other half deck that lies on the table.

POSITION CHECK: The deck lies face-down on the table minus eight cards. These eight cards form four back to back pairs which lie in a row on the table.

4. Draw attention to the pairs of cards and point out that the four face-up cards showing form a particular total (actually twenty-four), adding, "I couldn't have known in advance what that total would be because you chose the cards from a random place in the deck. However, just to make sure, I want you to alter the cards. Please turn over any pair of cards." When he does this a different value now appears on top. "OK. Now to be double sure, turn over another pair." Again this changes the upper value.

All appears fair and random, but nothing could be further from the truth because, thanks to the Sands principle, the four face-up cards now total twenty.

5. So, ask him to add together the four values to arrive at a grand total (twenty). Finally ask him to pick up the deck and count down to the twentieth card from the top. This will be his selection.
