Tricks with no sleight of hand in them at all. The deal does the work, which means you can learn one in an evening and spend your practice on the part that actually matters — what you say while it happens.
Each page here lets you run the trick on screen before you pick up a deck, and then explains why it cannot fail. The arithmetic is checked against every possible case rather than asserted, because "trust me, it always works" is what every other page already says.
Somebody thinks of a card among twenty-one. You deal three times, asking only which pile it is in, and you find it. Deal it through here and watch the possibilities collapse — then learn why their card is always the middle of the last pile, which means you never have to count to eleven.
Deal it through →A deck in a secret order that looks shuffled. Two small sums give you the card under any card named, and where any named card sits. Work it out against the real arithmetic here, then drill it with the sums hidden.
Learn the stack →It means the method is in the procedure rather than in your hands. No passes, no palming, no false shuffles — you deal cards according to a rule and the rule produces the miracle. A spectator can be holding the deck the whole time.
The trade is that these tricks are usually known. Every family has an uncle who does the 21 card trick badly. That is not the disadvantage it appears to be: what people have seen is the procedure, and what makes it play is everything around the procedure. A self-working trick performed well beats a difficult one performed adequately, every single time, and it never goes wrong in front of anybody.
