WHAT IS THE DIFFERENCE BETWEEN AN EXACTA AND EXACTA BOX?
--If you play "$1.00 Exacta 3-6", obviously, your ticket costs one dollar only. 
--After the race is completed, you're a winner IF AND ONLY IF horse #3 wins the race and horse #6 comes in second position. 
--If these horses came in reverse order: Let's suppose that horse #6 won the race and horse #3 came in second position.  Then, you DON'T have a winning ticket.  To be a winner, you would have had to buy a separate ticket "$1.00 Exacta 6-3".
--Instead, if you play "$1.00 Exacta Box 3-6", your ticket costs two dollars and you would be covered both front and back!
--You would be a winner whether horse #3 won the race and horse #6 came in second position, or if horse #6 won the race and horse #3 came in second position.
--In summary, a "box" bet covers BOTH combinations...front AND back...3-6 and 6-3.  After all, you paid $2.00 for both of these tickets: $1.00 for 3-6 and $1.00 for 6-3.
--On your ticket, 'Exacta box' or 'EXB' will be listed.

WHEN SHOULD I PLAY AN "EXACTA" BET VERSUS AN "EXACTA BOX" BET?
EXACTA bet:
--If you love a certain horse, you should play an exacta bet.  The first horse that you select MUST win the race.  The second horse that you select MUST come in second position.
--Example: You like horse #5 and you think it's going to win.  You like horse #2 for second position.  If you play "$1.00 Exacta 5-2", you're a winner if horse #5 wins the race and horse #2 comes in second.

​EXACTA BOX bet:
--In the above example, you think horse #5 is going to win.  But, if you're not sure which of these horses is going to win and which horse is going to come in second position, then you SHOULD play an Exacta box bet!
--If you play "$1.00 Exacta Box 2-5", it costs $2.00.  You're a winner either way: 1) If horse #2 wins the race and horse #5 comes in second position, OR 2) If horse #5 wins the race and horse #2 comes in second position. 
--Basically, you played the exacta bet...both front and back!
--This is a simple example that involves playing exacta box using two horses only.

CAN I USE THREE OR MORE HORSES TO PLAY EXACTA BOX BET?
Yes! 
--For example, you may play "$1.00 Exacta Box 3-6-8".
--As long as any of these three horses (#3, #6, and #8) come in the top two positions, you're a winner! For a $1.00 bet, this ticket costs $6.00.  The winning payoff amount depends on if favorites, long shots, or a mix of both came in the top two positions.
--I'm only scratching the surface here.  Regarding how much exacta box bets would cost using four, five, or more horses, check it out in my book!

WHAT IS THE DIFFERENCE BETWEEN A QUINELLA AND AN EXACTA BET?
--Let's suppose that you love horse #2 AND horse #5.  You want to play your bet SO THAT you're a winner whether horse #2 wins the race and horse #5 comes in the second position or horse #5 wins the race and horse #2 comes in the second position.
--If you play an exacta bet, then, you would have to play "$1.00 Exacta Box 2-5".  This bet costs $2.00 and you're a winner if horse #2 and horse #5 come in the top two positions in either order.
--The BIG difference is that Quinella covers the SAME BET AS ABOVE, but costs only half the price. 
--Example: If you play "$1.00 Quinella 2-5", you're a winner...IF horse #2 and horse #5 come in the top two positions in either order.  This bet costs $1.00 only; not $2.00 dollars!

Note: Usually an exacta bet pays higher amount than a quinella bet.

Another important factor to consider: In most cases, Exacta bets are available (to bet) in every race.  However, in most cases, quinella bets are available (to bet) in couple races only; usually, in the second and fourth races.

WHAT IS THE BEST WAY TO PLAY A SUPERFECTA BET?
--Even though a superfecta bet costs only ten cents, it's a much more complicated bet than what you think it is.
--The BEST answer is:  Play a "Superfecta Box" bet.
--As you know from above, a box bet means that the horses that you select may come in ANY order!
--If you played a straight bet "$0.10 Superfecta 1-9-8-5", then, all these four horses must come in the EXACT order (i.e., Horse #1 MUST win the race, horse #9 MUST come in second position, horse #8 MUST come in third position, and horse #5 MUST come in fourth position).  This bet costs ten cents only.
--What's tricky is that there are actually 23 'other' combinations of these numbers that exist! Some of them are: 1-9-5-8, 1-8-9-5, 1-8-5-9, 1-5-8-9, 1-5-9-8, 9-1-8-5, 9-1-5-8, 9-5-1-8, and 9-5-8-1.  So, if any of the other 23 combinations come in, you're not a winner.
--To cover "all" 24 horse number combinations, you should play "$0.10 Superfecta Box 1-9-8-5".  This box bet costs $2.40 only. 
--In summary, whichever four horse numbers that you select, you're a winner as long as ALL four of your horse numbers come in the top 4 positions!
