you play craps, you probably know the payoffs for most numbers on
place bets. For example, the odds on the six and eight are 7:6 (bet
$6, get $7), the odds on the five and nine are 7:5 (bet $5, get
$7) and the odds on the four and ten are 9:5 (bet $5, get $9). But,
when you want to add odds to your pass or come bets, the payoff
is different. This is because they are true odds, which means that
the casino has no advantage on these odds bets.
The odds for
the numbers six and eight are the same, 6:5. The odds for both the
five and nine are 3:2 and the odds for the four and ten are 2:1.
If you just subtract one from the smaller of these numbers and relate
it to six (the number of times a seven rolls) you get the true odds.
to get the true odds for the four or ten, just subtract one from
four (four is smaller than ten) to get three. So the true odds of
the four or ten are 6:3, or 2:1.
To get the true
odds for the six or eight, subtract one from six (six is smaller
than eight) to get five. So the true odds for the six or eight are
to get the true odds for the five or nine, subtract one from five
(five is smaller than nine) to get four, so the odds of the five
or nine are 6:4, or 3:2.
Here are some
examples with some typical added odds bets.
If you have
$10 on the come or pass line and your point is a five or nine, and
you want to add some odds, just subtract one from five to get four.
The true odds then is 6:4, or 3:2, so if you bet $20, you’ll
win $30. For double odds you can add $20 odds to your $10 flat bet
and win $10 from the flat portion and $30 from the odds portion,
for a total of $40.
If the point
is four or ten, subtract one from four to get three. The true odds
then are 6:3, or 2:1, so if you bet $20, you’ll win $40. For
double odds, you can add $20 to your flat $10 bet and win $10 on
the flat portion and $40 to the odds portion, for a total of $50.
The six or eight
is a little different. If you subtract one from six you get five,
which means the true odds are 6:5. If you have a flat bet of $10,
you would be able to take $20 in odds, (on a 2X odds table) however,
this would mean a $24 odds payout, which is awkward for most casinos.
So, to even things up, most casinos let you place $25 in odds behind
the 6 or 8, (which really gives you 2.5X odds instead 2X), giving
you $10 for the flat portion and an even $30 for the odds portion,
for a total win of $40.
works on don’t-come and don’t-pass bets as well, except
the odds are reversed. This is because on the don’t side you
have the advantage rather than the house, so you have to bet more
to get less.
