Vingt et un \
Vingt `
et `
un "\ [
F .,
twenty and one .]
A game at cards ,
played by two or more persons .
The fortune of each player depends upon obtaining from the dealer such cards that the sum of their pips ,
or spots ,
is twenty -
one ,
or a number near to it ; --
also called {
blackjack },
or {
twenty -
one }.
Note :
There are several variations (
such as {
Caribbean blackjack }).
In the most common variation played in casinos ,
there is one dealer who plays for the house ,
and up to seven players .
The players and dealer each receive two cards ,
the dealer '
s cards usually being one face up and one face down .
The players each in turn decide whether they will request additional cards ("
hit "),
the objective being to reach a sum of card values as close as possible to twenty -
one ,
without exceeding that number .
If ,
on hitting ,
the player '
s total card values exceed 21 ,
he has "
busted ",
and lost his bet .
Otherwise ,
the player wins only if his total card values exceed those of the dealer . "
picture cards "
(
or "
face cards ",
being the jack ,
queen ,
and king )
are counted as having a value of ten .
The ace may count as one or eleven ,
at the player '
s option .
Other than to hit ,
there are also other possible actions by the player ,
such as to "
double down " (
receive only one additional card ,
while doubling the initial bet ),
or to "
split " (
if the first two cards have the same value ).
