Edge sorting in poker

Edge sorting in poker is an advantage-play technique where a player uses tiny manufacturing or handling flaws on card backs to tell certain cards apart and gain information about unseen hands.

Also known as
Edge sorting (base term)
Legal status (England & Wales)
Held to be cheating in civil law 12

Key points

  • Edge sorting relies on physical card-back asymmetries, not mathematical tracking like card counting 3.
  • The player gets the dealer to orient certain cards in a known direction, making them distinguishable later 1.
  • In poker, the technique can be used to infer unseen cards, though it is more commonly discussed in casino table games 13.
