Part I: Card Game Cheating · SLEIGHT-OF-HAND TECHNIQUES
False Shuffle - Push-Through Shuffle
How it works
The push-through shuffle is another false riffle shuffle that appears legitimate but maintains card order. Unlike the Zarrow, in this technique the cards ARE interweaved during the riffle, but blocks of cards are then secretly pushed through each other to restore the original order. The dealer can pause mid-shuffle to seemingly “prove” the cards are intermixed, then complete the move to restore the stack. Testing has shown that many observers actually find the push-through MORE convincing than the Zarrow because of this “proof” moment.
