People love to bet the Horn and the Horn Highs during the Comeout Roll. It’s a one-roll bet and the payoffs can be pretty good but, like most other bets, it falls prey to a roll of the 7. This is where the World, aka Whirl, comes into play. The World is a combination of a Horn and an Any 7.
* All payments are in terms of a nickel on the World
The World is a one roll bet
A $5 World
The World needs to be bet in increments of five-dollars. A $5 World is a $1 on each the Aces, Ace Deuce, Yo, Twelve and the Any 7. The minimum is five-dollars because you must put at least $1 on those five bets. You can also consider a $5 World to be a $4 Horn with $1 on the Any 7.
Placement of a World
I would say that the majority of Craps tables don’t have a picture of the World on them. The World is more of a bet that dealer and players know by heart. Example 2 shows one of the other ways I've seen a world set up on a table without the globe image.
What does the World Pay
Like all other Mulit-Bets, the World pays differently depending on what rolls. There are three options: the 7 rolls, the high side rolls (2, 12), or the low side rolls (3, 11).
When the 7 rolls the World is a push; it does not win or lose. It’s a push because the dollar bet on the Any Seven wins four dollars, and that four dollars pays for the rest of the losing bets in the World: the Aces, Ace Deuce, Yo and Twelve.
Low Side (3,11) Rolls
The Low Side is considered the Ace Deuce or the Yo. When they hit for a dollar they pay $15 minus $4 (the rest of the other four losing bets) for a payment of $11.
Ace Deuce Rolls
High Side (2,12) Rolls
The two High Side numbers are the Aces and Twelve. When either of these numbers roll they pay $30 minus $4 (the rest of the other four losing bets) for a payment of $26.
Betting the World for the Dealers
Ideally, multiples of $5 would be best for the dealers. Anything less would be an improper bet than requires some odd math for the dealers and usually ends up getting rounded down.
