Lottery wheeling. Lottery wheeling (also known as lottery system, lottery wheel, lottery wheeling system) is used by individual players and syndicates to distribute a subset of the possible lottery numbers across multiple tickets to ensure that at least one of these tickets will contain a winning combination if several draws are in this subset.
This is when you are betting that one of three numbers hits on the roulette wheel. The payoff for a bet like this is 11 to 1. So if you bet $10 and bet on either 13, 14, or 15 to hit, you would win $110 if any of the three hit.
