Wheeling System (lotto)
A way of organizing lotto-type game play to improve chances
of winning multiple tier-prizes. Wheeling Systems "arrange"
a group of selections (8, 10, 12 numbers or more) into multiple
games that give either full or partial coverage of all the possible
combinations of those selections. A full wheel covers all permutations
of the selected numbers and is usually very expensive. If the
numbers drawn are present in your group of selections, though,
you are guaranteed a winning ticket. An "abbreviated"
system is much cheaper. It does not guarantee a jackpot, but
usually guarantees tier prizes.
