The primary advantage to playing a double-deck game is the volatility of the count. Unlike a 4- or 6-deck game, the running count, which is converted to the True Count (count per remaining deck) in a DD game can rise or fall quickly, but it’s gone almost as fast, due to the shuffle.

Introduction

Super Sevens/Crazy Sevens/Lucky Sevens is a blackjack side bet based on the player's first three cards. If the first card is a seven, the player wins. The winnings increase for two or three consecutive sevens and even more if the sevens are suited.

Mega cgr casino auxerre. This analysis assumes that if the player gets two sevens and splits, then his first card to the first hand will count towards a possible three-card seven.

What is not always clear is what happens if the player has two sevens and the dealer gets a blackjack. I assume that the player is paid for two sevens with no chance for a third card. I can say this is definitely the rule with Lucky Sevens. However, I analyzed the game both ways below.
