EFFECT: The magician writes down a prediction on a piece of paper and hands it to a spectator for safe keeping. He then displays four cards which each contain a design similar to an electronic circuit board along with four different colored "fuses." A spectator is asked to set each of the different fuses in front of any card they like. The cards are then turned over, revealing four sets of 4 digit numbers. The four different sets of numbers are printed in the same colors as the four fuses. Whichever color fuse the spectator set in front of each card determines which number will be used from that card. These four selections are added together and it matches the magician's prediction exactly!

• Instantly repeatable with a different prediction and outcome!
