A wheel is a type of algebra (in the sense of universal algebra) where division is always defined. In particular, division by zero is meaningful. The real numbers can be extended to a wheel, as can any commutative ring.
Lottery wheeling (also known as lottery system, lottery wheel, lottery wheeling system) is a method of selecting multiple lottery tickets, widely used by individual players and syndicates to secure wins provided they hit some of the drawn numbers.
