Keno
The modern version of an old Chinese lottery. Twenty number
out of eighty are drawn,
and players win by guessing which numbers will be drawn. Keno
is a lottery; state lotteries are variations of keno.
Keno (lotto)
A lotto game in which a set of numbers (typically 20) is selected
from a large field of numbers (typically 80). Players select
a smaller set of numbers (up to 10) and are awarded prizes based
on how many of their numbers match those in the drawn set. Players
have discretion over how many numbers to select, and can choose
to play for a small prize with good odds (by selecting a small
set of numbers such as three), a large prize with much greater
odds (by selecting a large set of numbers such as 10) or combinations
in between. In casinos, and with several lotteries, keno is
played at frequent intervals, with drawings as close together
as every five minutes.
