Guesstimation by Wayne Dobson

Experience the art of Guesstimation with Mike Sullivan and Peter Nardi. This innovative trick requires just one-time setup for endless performances.

Master the skill of instantly determining how many cards have been removed from a standard deck of 52. In this routine, a spectator cuts a portion of the deck, and you confidently reveal the exact number—18 cards. After verifying your accuracy, you repeat the process, impressing them once more. For the third demonstration, you predict the count using a business card. When the spectator counts 27 cards, you cleverly state, “So I was right, there are 25 cards… plus 2,” revealing the business card for a surprising twist!
