Here is a very simple overview of a Zone wheel.
Suppose you have 15 numbers that you want to play.
Of those 15 numbers, 5 are your real favorites.
The other 10 numbers are there for a kind of insurance. In other words, you don't expect that more than 1 or 2 of them might win.
... You want to include those 10 numbers.
... But of course, you don't know "which" 1 or 2.
You can use a Zone wheel.
You can put those 10 numbers into a Zone. Tell the software to play 1 or 2, at a time, from that Zone.
The software will wheel the numbers, making sure that out of your 10 "insurance" numbers:
... No less than 1, and no more than 2, of them will show up in any combination.

You can make a wheel with several Zones. You just specify how many numbers (minimum and maximum) you will allow to be wheeled together, from each Zone.

The difference between a Zone wheel and an Abbreviated or Full wheel is that the Zone wheel has a lower cost than either of those types.
Go back to the wheel example mentioned above.
... If you want to treat all 15 of your numbers equally in your wheel, then you'd use an Abbreviated wheel or Full wheel. But that will be costly, especially for the Full wheel.
... On the other hand, if you have (say) 5 personal "favorite" numbers, plus 10 other "less-favorite" numbers, then you can consider using a Zone wheel. You can have fuller coverage of your preferred numbers, while still getting some control over the rest of the numbers.
The difference between the Zone wheel, and the other two wheels, is that you are concentrating your playing cost on covering your "favorite" numbers.
That is, you're covering your preferred numbers more completely than in an Abbreviated wheel, while still giving some coverage for the other numbers.
One way to see it is: Every combination is a cost to you. You're concentrating your budget on your preferred numbers.
