If you selected through your analyses the exact number of balls needed for a game, you would generate one ticket. However, if you create more than the minimum number of balls and wanted to play multiple tickets, you might use a wheel to spread the numbers out so that if some combination of the numbers you choose get picked, you have a good assurance that you’ll have generated winning tickets, if not a huge jackpot.
Wheels are designed with a specified number of tickets to be played for the numbers
you choose to generate assured wins if all those tickets are played. For example, if
you have generated 10 chosen numbers, a wheel might generate 5 tickets, 11 tickets,
and 31 tickets, as three examples. You would choose the 5-ticket wheel if you were a
more conservative player and the 31 ticket wheel if you were an aggressive player
that was willing to spend more to improve your chances of winning. However, you
could also choose the 31 ticket wheel and play only 12 of those numbers. You would
still have great tickets, but by not playing all of the tickets on the wheel, your
assurance of cashing if winning numbers are called might be reduced.
