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. By betting the Any 7 as part of the World, you offset losing when a 7 rolls.
