Q:C1 What special terminology is used at the Craps table?
A:C1 (Steve Jacobs, Ken Elliott III, Dave Everett)

Craps Terminology:

any craps
     a bet that the next roll will be 2, 3, or 12. This bet pays 7:1 and has a
     house edge of 11.1%.

3-way craps
     a bet made in units of 3 with one unit on 2, one unit on 3, and one unit
     on 12. This is a horn bet without the bet on 11.

any seven
     a bet that the next roll will be 7. This bet pays 4:1 and has a house edge
     of 16.7%.

big 6
     a bet that a 6 will be rolled before a 7 comes up. This bet pays even
     money, and has a house edge of 9.1%. A place bet on 6 pays 7:6 but is
     identical otherwise. The place bet is preferred, having a house edge of
     1.5%

big 8
     a bet that an 8 will be rolled before a 7 comes up. This bet pays even
     money, and has a house edge of 9.1%. A place bet on 8 pays 7:6 but is
     identical otherwise. The place bet is preferred, having a house edge of
     1.5%

buy bet
     giving the house a 5% commission in order to be paid correct odds for a
     place bet. The buy bets on 4 and 10 allow the player to reduce the house
     edge from 6.67% to 4% on these bets. Some casinos collect the commission
     only on winning bets, while others collect it at the time the bet is made.

come bet
     A "virtual pass line bet"; a bet made after the come out roll but in other
     respects exactly like a pass line bet. See question C5 for more details.

come out roll
     the first roll of the dice in a betting round is called the "come out"
     roll. Pass bets win when the come out roll is 7 or 11, while pass bets
     lose when the come out roll is 2, 3, or 12. Don't bets lose when the come
     out roll is 7 or 11, and don't bets win when the come out roll is 2 or 3.
     Don't bets tie when the come out roll is 12 (2 in some casinos; the "bar"
     roll on the layout indicates which roll is treated as a tie).

dice pass
     The dice are said to "pass" when the shooter rolls a 7 or 11 on the
     come-out roll. The dice "don't pass" when the shooter rolls a 2, 3, or 12
     on the come-out. If the come-out roll is a 4, 5, 6, 8, 9, or 10, this roll
     sets the "point", and the shooter continues to roll until the point is
     rolled again or a 7 is rolled (see "seven out"). If the shooter rolls the
     point before rolling a seven, the dice pass. If the shooter sevens out,
     the dice don't pass and the shooter loses control of the dice. NOTE: in
     this context, "pass" does NOT mean that the dice to given to the next
     player. Control of the dice is transferred only when the shooter "sevens
     out" or when the shooter has completed a game and no longer wishes to roll
     the dice.

don't come bet
     A "virtual don't pass bet"; a bet made after the come out roll but in
     other respects exactly like a don't pass bet. See question C5 for more
     details.

don't pass bet
     a bet that the dice will not pass. This bet can be placed only immediately
     before a "come out" roll. One result (either the 2 or the 12, depending on
     the casino) will result in a push. House edge on these bets is 1.40%. A
     don't pass bet can be taken down, but not increased, after the come-out
     roll.

double odds
     an odds bet that is about twice as large as the original pass/come bet.
     Some casinos offer higher odds, such as 5X or even 10X odds.

field bet
     a bet that the next roll will be 2, 3, 4, 9, 10, 11, or 12. This bet pays
     even money for 3, 4, 9, 10, and 11, and usually pays 2:1 for 2 or 12. Some
     casinos pay 3:1 for either the 2 or 12 (but not both), and some casinos
     may make the 5 instead of the 9 a field roll.

hard way
     a bet on 4, 6, 8, or 10 that wins only if the dice show the same face;
     e.g., "hard 8" occurs when each die shows a four.

hop bet
     a bet that the next roll will result in one particular combination of the
     dice, such as 2-2 (called a "hopping hardway") or 3-5. 2-2, 3-3, 4-4, and
     5-5 are paid the same as a one-roll 2; other hop bets are paid the same as
     a one-roll 11.

horn bet
     a bet that the next roll will be 2, 3, 11, or 12, made in multiples of 4,
     with one unit on each of the numbers.

horn high bet
     a bet made in multiples of 5 with one unit on 3 of the horn numbers, and
     two units on the "high" number; e.g., "$5 horn high eleven": $1 each on 2,
     3, 12, and $2 on the 11.

lay bet
     a bet that a particular number (4,5,6,8,9, or 10) will NOT be rolled
     before a 7 comes up. The casino takes 5% of the winnings on these bets.
     The 5% commission is usually taken up front, but some casinos take the
     commission after the bet wins.

lay odds
     after a point has been established, the don't pass bettor can place an
     additional odds bet that will win if the original don't pass bet wins. The
     odds bet is paid at the correct odds for the point, and is a fair bet with
     no house edge. This also applies to a don't come bet. Making this bets is
     referred to "laying the odds" for your don't bet.

line bet
     a bet on the "pass line" or the "don't pass line" is called a "line" bet.
     These bets are placed at the beginning of the game, before the "come out"
     roll. The shooter is required to make a line bet in order to shoot the
     dice.

odds off
     odds bets that are "not working". Odds bets can be called "off" by the
     player at any time, but are left on the felt until the bet is resolved.
     Also, come odds bets are usually "off" during the come out roll, unless
     the bettor asks to have the odds bets "working". Come odd bets that are
     "off" will be returned to the player if the line bet loses on the come out
     roll. Don't come odds generally work on the come-out roll.

pass bet
     a bet that the dice will pass, also known as a "pass line" bet. This bet
     is generally placed immediately before a "come out" roll, although you can
     make or increase this bet at any time. House edge on this bets is 1.41%.

place bet (to win)
     a bet that a particular number (4, 5, 6, 8, 9, or 10) will be rolled
     before a 7 comes up. These bets are paid at slightly less than correct
     odds, giving the house an edge of 1.52% on 6/8, 4% on 5/9, and 6.67% on
     4/10.

place bet (to lose)
     a bet that a 7 will be rolled before the number you are placing
     (4,5,6,8,9, or 10) comes up. The casino requires you to lay slightly more
     than the correct odds, giving the house an edge of 3.03% on 4/10, 2.5% on
     5/9, and 1.82% on 6/8.

point
     if a 4, 5, 6, 8, 9, or 10 is rolled on the come out roll, then this number
     becomes the "point". The shooter must roll the point again, before rolling
     a seven, in order for the dice to "pass". A "come point" is just the
     number that is serving as a point for a come bet.

put bet
     1. A bet made on the pass line after the come out roll. This is allowed in
     Las Vegas and at Turning Stone, but not in Atlantic City and not at
     Foxwoods. This is not recommended, as 45% of your pass line wins are made
     on the come-out roll. 2. A bet made directly onto a come point number.
     E.g., "Put $5 and $10 odds on the six." Not recommended for the same
     reasons given in 1.

right bettor
     a player who bets that the dice will pass.

seven out
     when the shooter rolls seven after a point has been established. Control
     of the dice is transferred to the next shooter. Another term for this is
     "miss out." You will sometimes hear players call this something else, but
     we can't print those things here. This is often incorrectly called "crap
     out."

shooter
     the player who is rolling the dice. The shooter must place a "line" bet
     ("pass" or "don't pass") in order to be eligible to roll the dice. Of
     course, the shooter can place other bets in addition to the required
     "line" bet. Most shooters (and players) tend to play the "pass" line. Note
     that shooters who make "don't pass" bets are not betting against
     themselves, they are simply betting that the dice will not "pass".

single odds
     an odds bet that is about as large as the original pass/come bet. Some
     casinos allow "double odds", or even larger odds bets.

take odds
     after a point has been established, the pass/come bettor can place an
     additional odds bet that will win if the original pass/come bet wins. The
     odds bet is paid at the correct odds for the point, and is a fair bet with
     no house edge.

two ways
     a phrase appended to a hardway or proposition bet to indicate that the
     player is betting one chip for the dealers along with his own bet. A $2
     bet two ways is $1 for the player and $1 for the dealers; a $6 bet two
     ways is $5 for the player and $1 for the dealers; a $10 bet two ways is $5
     for the player and $5 for the dealers. E.g., "Hard 6, two ways" or
     "Two-way hard 6."

working
     bets that are "live" (i.e., can be resolved with the next roll) are said
     to be working. Generally, place bets, buy/lay bets, and come odds bets do
     not work on the come-out unless you tell the dealers to "make them work."
     All other bets (e.g., hardways) work unless you call them "off" (i.e.,
     tell the dealers you do not want them to "work").

world bet
     a bet that the next roll will be 2, 3, 7, 11, or 12, made in multiples of
     5, with one unit on each of the numbers.

wrong bettor
     a player who bets that the dice will not pass.

Q:C2 How is Craps played?
A:C2 (Dave Decot, Frank Irwin, Alan Mintz, Ken Elliott III, Jeffrey Osier)

Casino craps is played completely against the casino, on a big felt layout set
inside a large table with high rails around the side so you can bounce the dice
off 'em and still keep 'em on the table. Up to between 12 and 16 people can
play at once, depending on the size of the table (obviously). The layout looks
something like:


           Dealer stands         Boxman sits          Dealer stands

Each player bets a minimum amount determined by the table.

Each die has six sides, each side with a different number of spots from one to
six.

Two such dice are rolled by one player called the "shooter". The shooter must
place a "pass" bet or a "don't pass" bet in order to be eligible to roll the
dice. Exception: the shooter can let his Hot Babe (TM) roll the dice for him if
he has a pass or don't pass bet down.

The total number of spots on the tops of the dice after the shooter has rolled
is called the "roll".

A game consists of a series of rolls.

A roll of 2, 3, or 12 is called "craps".

The first roll by the shooter during a game is called the "come-out roll".

If the come-out roll is 7 or 11, the game is over:
     Bets on the "Pass line" win 1:1.
     Bets on the "Don't Pass line" lose.
If the come-out roll is craps, the game is over:
     Bets on the "Pass line" lose.
     Bets on the "Don't Pass line" win unless:
     The "Don't Pass" line says "Bar " and the roll is the indicated value, in
     which case the bet pushes.

Otherwise, the come-out roll becomes the "point", and a large white marker is
placed on the number representing the point (4, 5, 6, 8, 9, or 10).

For each roll in a game subsequent to the come-out roll:
     If the roll is the point, the game is over:
     Bets on the "Pass line" win 1:1.
     Bets on the "Don't Pass line" lose.
     If the roll is 7, the game is over:
     Bets on the "Pass line" and lose.
     Bets on the "Don't Pass line" win 1:1.
     The turn of the "shooter" is over.
     Otherwise, the game continues and the shooter rolls again.

During a game, bets on the Pass line cannot be removed; they can, however, be
increased. Bets on the Don't Pass line may be decreased or removed, but not
increased.

When a game is over:
     If the game was over on the come-out roll, or because the point was rolled
     again, the shooter may continue to be the shooter for another game, or
     pass the dice on to the player just clockwise, who becomes the new
     shooter.
     Otherwise, the shooter must pass the dice on to the player just clockwise,
     who becomes the new shooter.

Note: The other bets that can be made and resolved are not detailed above for
purposes of saving space. A description of when these bets win or lose is given
in question C1.
    ------------------------------------------------------------------------


Q:C3 What are "Odds"?
A:C3 (Matt Wilding, Ken Elliott III)

Casinos allow a player to place "odds" on pass, don't pass, come, and don't
come bets after a "point" has been established. If the bet on which odds are
placed wins, the odds bet is paid fairly. This means the odds on pass and come
bets are paid 2-1 for the 4 and 10, 3-2 for the 5 and 9, and 6-5 for the 6 and
8. The odds for don't pass and don't come bets are paid 1-2 for the 4 and 10,
2-3 for the 5 and 9, and 5-6 for the 6 and 8 (this is called "laying" odds).

The player should make odds bets that can be paid exactly, or the dealer will
pay off by rounding down. Odds on the pass line and come bets should be a
multiple 5 if the point is 6 or 8 and a multiple of 2 if it's a 5 or 9. (Don't
betters can figure this out themselves.)

Casinos advertise the maximum odds bets they allow as the maximum amount
"times" the original bet the odds bet may be (for don't pass and don't come
bets, it's the maximum amount "times" the expected win). You can increase your
odds bet over this advertised maximum only enough to allow you to make an odds
bet that can be paid exactly.

A player can modify his odds bets at any time.
    ------------------------------------------------------------------------


Q:C4 What is the house advantage on 10x odds?
A:C4 (Ken Elliott III, David Escoffery)

The following table lists the house advantage for a pass bet and don't pass bet
with the indicated odds. Remember, the house advantage indicates
(mathematically) the percentage of your bet handle that the casino will win in
the long run. Be aware, too, that higher odds often means a higher bet handle,
which in turn leads to higher "variance;" that is, your bankroll may exhibit
greater swings if you're used to betting $15 a hand ($5 pass bet at double
odds) and suddenly start betting $55 a hand ($5 pass bet at 10x odds).

    ------------------------------------------------------------------------


Q:C5 What are "Come" and "Don't Come" bets?
A:C5 (Dave Decot, Frank Irwin, Alan Mintz, Ken Elliott III)

Other bets can be made during the game after the come-out roll by anyone,
called "Come" and "Don't Come" bets. These are made by placing the bet on the
"Come" box or the "Don't Come" box; these bets are regarded as Pass (Don't
Pass) bets, but as if the very next roll of the dice were the "come-out" roll
of a new game. For example, if a come bet is made and if the next roll is 7 or
11, the Come bet wins immediately; if the next roll is 2, 3, or 12, the Come
bet loses immediately; otherwise, the number rolled is the point for that Come
bet (called a come point). Such a Come bet is moved onto the area of the table
where its point appears, awaiting a roll of either its point or seven. The game
for a Come bet always continues until this happens, even though the shooter
rolls the point for the Pass line, even though the shooter begins a new game
for the Pass line, even though another shooter begins rolling, as long as the
termination conditions for that Come bet have not yet occurred.

Note that rolling a seven always terminates all Pass, Come, Don't Pass, and
Don't Come games on the table; since it results in immediate win or loss.

The payoffs for Come and Don't Come bets are the same as for Pass and Don't
pass bets.

It is possible to place odds bets on the points of your own Come and Don't Come
bets by handing the bet to a dealer and stating that you want "odds on my ".
Unless you specify otherwise, odds bets on Come are declared "not working" on a
come out roll after a point is made. However, odds on Don't Come bets are
usually working by default.
    ------------------------------------------------------------------------


Q:C6 What are all those other bets?
A:C6 (Dave Decot, Frank Irwin, Ken Elliott III)

Other bets are possible:

Place bets (to win):
     Bets that an indicated number will be rolled before 7 is rolled (come-out
     rolls are ignored for the purpose of determining this, unless otherwise
     specified by the player making the bet).

Place bets (to lose):
     Bets that a 7 will be rolled before the indicated number is rolled
     (come-out rolls are ignored for the purpose of determining this, unless
     otherwise specified by the player making the bet).

One roll bets:
     Bets that a certain roll, or a certain pair of dice faces, or one of
     several rolls, will appear on the next roll of the dice. Such bets may be
     made before any roll. These all pay higher than 1:1, This includes "Any
     craps", "eleven", "seven", "Horn", and "field" bets.

Field:
     A special case of one-roll bet. This pays 1-1 whenever 3, 4, 9, 10, or 11
     is rolled, and possibly higher amounts when 2 or 12 is rolled.

Hardways:
     Bets that a certain pair of dice faces will appear before 7 is rolled, and
     before any other pair of dice faces with the same total value are rolled.
     For example, a bet on "hard 4 (2 and 2)" loses when (1 and 3) is rolled,
     because this is an "easy way" to roll 4. A bet on "hard anything" loses
     when 7 is rolled.

Hopping hardways:
     Bets that a certain pair of identical dice faces will appear on the next
     roll. These all pay 30:1 (or sometimes higher or lower).

Horn bets:
     Basically, just betting on the 2,3,11, and 12 at once. This requires 4
     units, since you are really making 4 bets.

    ------------------------------------------------------------------------


Q:C7 What are the odds for all these bets?
A:C7 (["Winning Casino Craps" by Edwin Silberstang], Ken Elliott III)

Note that some casinos offer different payouts for prop bets, lower
(promotional) commission on buy/lay bets, and collection of buy/lay bet
vigorish only on winning bets, all of which change the "Casino Advantage"
listed below. The numbers below represent those most commonly seen in Las
Vegas.

In practically all casinos, odds on proposition bets are quoted as "x for y",
which means that the casino takes your winning "x" bet and pays you "y", in
contrast to what is done for other winning bets (e.g., if the "Any 7" bet is "5
for 1", when making a $1 bet and winning the casino will take your $1 and give
you $5, for a "real" payoff of "4 *to* 1"). The numbers below are quoted as
"x:y", not "x for y".
