Horn High
There are four different Horn High’s that all bet the same numbers as the Horn. They are the Horn High Yo, Horn High Ace Deuce, Horn High Aces, and the Horn High Twelve. The difference is you are adding a higher amount of money to one of those bets; the Aces, Aces Deuce, Twelve, or the Yo in order to determine which Horn High you’re betting.
* All bets have a 5% commission fee

All the Horn Highs are one roll bets

The Horn High is a oneroll bet and it must be bet in increments of five dollars.
Four Different Horn High's
If you bet a fourdollar Horn then took another dollar and added it to the Yo then you would be betting a Horn High Yo. If instead you took that extra dollar and put it on the Twelve you would be betting a Horn High Twelve. I presume the Horn High was created in order to make betting simpler. Betting four dollars requires either splashing four (4) dollar cheques or betting a fivedollar cheque then having the Stickperson tell the base dealer to give a dollar change. Either way, it’s easier to make a fivedollar bet.

Placement of a Horn High
For the most part, all of the Horn Highs are separated into two sections: the left side of the table and the right side of the table. If two players from the same side of the table bet the same Horn High we wouldn’t even be able to fit both cheques in the box. There isn’t enough room for them both so we would have to go over the edges or put the edge of one cheque on top of the other. Whatever we need to do in order to get an understanding of where the bets should be.
What does the Horn High Pay
The Horn High’s are some of the most confusing bets to pay on a Craps table. There are only four payments you need to know in order to pay all the bets but it’s knowing when to apply each of those four numbers that makes paying them so difficult. You need to understand a few things before you’ll be able to figure out the payments of the Horn Highs right off the bat.

Directly  means the Horn High that you bet is the number that rolled. E.g. you bet the Horn High Twelve and the Twelve rolled or you bet the Horn High Ace Deuce and the Ace Deuce That is a direct hit.

Indirectly  means one of the other numbers rolled. E.g. you bet the Horn High Aces and the Twelve rolled or you bet the Horn High Yo and the Aces Those are indirect hits.

The Horn High Aces and the Horn High Twelve pay the exact same when they hit directly or indirectly because both the Aces and the Twelve pay 30 to 1. They are both considered the high side.

The Horn High Ace Deuce and the Horn High Yo pay the exact same when they hit directly or indirectly because both the Ace Deuce and the Yo pay 15 to 1. They are both considered the low side.
$5 Horn High Aces and Horn High Twelve
There are three possible outcomes/payments when you have to pay both the Horn High Aces and the Horn High Twelve:

$57  The bet hits directly

$26  The opposite high side number is rolled. E.g. you bet the Horn High Aces and the Twelve rolled.

$11  The low side rolled. E.g. you bet the Horn High Twelve and the Ace Deuce or Yo rolled. Ace Deuce and Yo are the low side numbers.
The Bet Hits Directly  $57
A $5 Horn High Aces has $2 on the Aces and $1 on the other three numbers. If the Aces rolled it would win $60 ($2 x 30) minus $3 (the other losing bets – $1 on each the Twelve, Ace Deuce, and Yo) for a payment of $57.
$5 Horn High Twelve Direct Hit
$5 Horn High Aces Direct Hit
Opposite High Side (2,12) is Rolled  $26
A $5 Horn High Twelve has $2 on the Twelve and $1 on the other three numbers. If the opposite high side rolled, the Aces, it would win $30 ($1 x 30) minus $4 (the other losing bets – $2 on the Twelve and $1 on each the Aces Deuce and Yo) for a payment of $26.
$5 Horn High Twelve and Opposite High (2) Side Rolls
The Low Side (3,11) is Rolled  $11
A $5 Horn High Aces has $2 on the Aces and $1 on the other three numbers. If an Ace Deuce rolled it would win $15 ($1 x 15) minus $4 (the other losing bets – $2 on the Twelve and $1 each on the Aces and Yo) for a payment of $11. Since the Yo pays the same as the Ace Deuce, if their places were switched, the end payment ($11) would still be the same.
$5 Horn High Aces and a Low Side (3,11) Rolls
$5 Horn High Ace Deuce and Horn High Yo
There are three possible outcomes/payments possible when you pay both the Horn High Ace Deuce and the Horn High Yo.

$27  The bet hits directly

$11  The opposite low side number is rolled. E.g. you bet the Horn High Yo and the Ace Deuce rolled.

$26  The high side rolled. E.g. you bet the Horn High Ace Deuce and the Aces or Twelve rolled. Aces and Twelve are the high side numbers.
The Bet Hits Directly  $27
A $5 Horn High Yo has $2 on the Yo and $1 on the other three numbers. If the Yo rolled it would win $30 ($2 x 15) minus $3 (the other losing bets – $1 on each the Ace Deuce, Aces, and Twelve) for a payment of $27.
$5 Horn High Yo Direct Hit
Opposite Low Side (3,11) is Rolled  $11
A $5 Horn High Ace Deuce has $2 on the Ace Deuce and $1 on the other three numbers. If the opposite low side rolled, the Yo, it would win $15 ($1 x 15) minus $4 (the other losing bets – $2 on the Ace Deuce and $1 on each the Aces and Twelve) for a payment of $11.
$5 Horn High Ace Deuce and Opposite Low (11) Rolls
The High Side (2,12) is Rolled  $26
A $5 Horn High Yo has $2 on the Yo and $1 on the other three numbers. If a Twelve rolled it would win $30 ($1 x 30) minus $4 (the other losing bets – $2 on the Yo and $1 each on the Ace Deuce and Aces) for a payment of $26. Since the Twelve pays the same as the Aces, if their places were switched, the end payment ($26) would still be the same.
