He learned this game when he was around 10 years old from older relatives in Jordan, trying to mimic the adults playing Blackjack 21.
The game can have many players, and it requires a standard deck of cards without 8s, 9s, 10s, and Jokers.
In order to choose the dealer, each player draws a random card from the deck. Whoever has the highest number is the dealer. Picture cards–like Kings, Queens, and Jacks–are worth ½, and the Ace is worth 1. However, the Queen of Hearts can either be any whole number from 1-7, or ½, depending on the player’s choice.
The game is played similarly to Blackjack 21, so each player asks for cards until they feel like they will go over 7½, called “burn” here instead of “bust,” or until they get 7½, at which they must flip over all their cards. Each player places a bet on their card before taking another card from the dealer, called taking a “hit,” and the amount can’t be changed after they take a hit. When the player no longer wants cards from the dealer, they will say that they are “asleep.”
The dealer, after all the players are burnt or asleep, takes cards and “wakes” players (asks them to show their cards) as they please. If the dealer’s total is greater than the player’s who was woken up, the dealer gets the money placed on the card. If it’s the other way around, the dealer must pay the player the amount on the card. If the totals are equal, no money is exchanged. If the dealer burns while taking a hit, they must pay each player that is asleep the amount on their cards.
If a player gets 7½ in two cards, they become the dealer in the next round unless someone else gets it in two cards as well. In the latter case, they decide who becomes the dealer. The dealership can also be sold to another player by the current dealer even if they did not get 7½ in two cards.
(I added the parentheticals to the original explanation for the sake of clarity)
This is one of my favorite card games; I learned it from my parents and grandparents when I was in middle school. Because the length of the game is not proportional to the size of the deck, but rather to the skills of the players, a single game can go for over an hour before somebody runs out of money. I remember we would play it whenever we knew that we could sit uninterrupted for a couple of hours, usually at night. Although it appears to be a child’s version of Blackjack 21, it can bring the whole family together, which leads me to believe that the reason this game has not been replaced by Blackjack 21 is because of how well it engages the whole family.
