Vegas by Virgin Games
Keno at Virgin Games
is a lottery-like or bingo-like gambling game
played at modern casinos. A traditional live casino
keno game uses a circular glass enclosure called
a "bubble" containing 80 ping pong-like
balls which determine the balldraw result. Each
ball is imprinted with a number 1 through 80.
During the balldraw, a blower pushes air into
the bubble and mixes the balls. A "caller"
presses a lever opening a tube, where the balls
lift one at a time into a "V" shaped
tube called the "rabbit ears". The caller
and a "verifier" record each of 20 balls
drawn, and the computerized keno system calculates
all wagers based on the numbers drawn.
Players wager by marking an "X" over
the "spot" choices on a blank keno ticket
form with 80 numbered selection boxes (1 to 80).
After all players successfully place their wagers,
the casino draws 20 balls (numbers) at random.
Some casinos automatically call the balldraw at
preset timed intervals regardless of whether or
not players are waiting to place a wager.
Each casino sets its own series of pay scale choices
called "paytables". The player is paid
based on how many numbers drawn match the numbers
selected on the ticket and according to the paytable
selected with regard to the wager amount. Players
will find a wide variation of keno paytables from
casino to casino and a large deviation in the
house edge set for each of those paytables. Additionally,
each casino typically offers many different paytables
and specialty keno bets for customers to choose
from, each with its own unique house edge. No
two casinos' keno paytables are identical. There
are several Reno and Las Vegas casinos offering
as many as 20 or 30 different paytables from which
the player can choose.
The house edge ranges from less than 4% to 66%.The
typical house edge for non-slot casino games is
between 0% and 5%. (Credit:
