Cooler (blackjack)
Colloquial expression for the pack of pre-arranged cards (usually
in 6- or 8-deck games)
with which a cheating team, through collusion with pit crew
members and especially the dealer, replaces the original casino
cards, just before their insertion in the shoe.
Extremely profitable for the cheaters if they can pull it off
and a most serious felony for everyone involved.
