Many sets of higher-end playing cards, including Denexa 100% Plastic Playing Cards, include two decks of cards—a red deck and a blue deck. But most card games require the use of only one 52-card deck. So why offer two decks?
The answer is simple—it makes your game more efficient! While you are using one deck to deal a hand, the next player to deal can be shuffling the other deck. That way, when the hand concludes, the next hand can be dealt immediately, without having to wait for a shuffle. The backs of the cards are in contrasting colors in case cards from the two decks get intermingled; it is obvious when a deck is incorrect.
The next time you spread a game, try keeping both decks of cards moving around the table if you don’t already. You’ll be happy with how much faster the game moves!
