Blackjack cut card

A blackjack cut card is a brightly coloured blank plastic card that the dealer places inside the shoe to show where the deck ends and a shuffle must happen.

Marks the end of a shoe and signals a shuffle is needed1
Placement
Inserted near the bottom of the shoe during preparation1
Applies to
Blackjack dealt from a shoe in casino play1

Key points

  • The dealer inserts the cut card during shoe preparation; when reached, it signals the current game is the last before a new shuffle.1
  • A cut card is not a strategy aid — it is a dealing marker, unlike a blackjack strategy card or basic strategy card.12
