This what I don't get..... (1) Exacta Part-Wheel bet, either a Front Wheel (1 x 3) or Back Wheel (3 x 1)
Ok, a Three Horse Part-Wheel is when you use say the # 3 horse on Top ( 1st Place )
and the #1, 2 & 4 on the bottom ( 2nd place ) ** of course you can use Any Numbered Horse.
The above is a Front Wheel........
a Back End part Wheel would be using the same horses Above. #1,2 & 4 with the #3 horse.
Meaning either the 1,2 or 4 need to Win the race, and the #3 Needs to finished 2nd
Here's More Info..............
Exactas can also be played as part-wheels, which differs from a full wheel in that you do not use ALL the horses in one part of the wheel. For example, in an eight-horse field, you might play a $1 exacta part-wheel 3 with 2, 4, 5 (three possible winning combinations of 3-2, 3-4, 3-5) at a cost of $3. Or you might play the part-wheel the other way, 2, 4, 5 with 3 (also three possible winning combinations of 2-3, 4-3, 5-3) at a cost of $3. While exacta wheels and part-wheels are not quite as inefficient as boxes, they still leave room for improvement, which brings us to our preferred exacta betting strategy.
