There are also wheels that use key numbers. A key number is one or more numbers that when placed in the wheel will then be contained in every bet/ticket that is generated by the wheel. If you are really sure that a certain number will occur in the upcoming draw then a key number wheeling system is for you.

All your tickets generated by this type of wheeling system will contain your special number. The purpose of key number wheeling systems is to of course include your lucky number(s) in all of your tickets but also to significantly reduce the number of tickets necessary to produce the wheels win guarantee. If your lucky number hits along with some other picks in your wheel you will have lots of tickets to cash.
