Keno has it’s origins in China, where it was used to raise
money for national defence. It is rumoured to have funded the
building of the Great Wall of China!. It was taken to the US by
eastern railroad workers in the 1800s.
Because keno is entertaining and easy
to learn, it has become widely popular. Like bingo, keno is a
lottery-type game of chance where anyone can win big. Keno’s
popularity in the US is driven by it’s quick and simple
gameplay. Visit any Vegas casino and you can play Keno in the
café’s, bars and many restaurants! However, visit
an Atlantic City casino and you won’t find it anywhere –

Of The Game
The objective of Keno is for the player to guess which numbers,
from 1 to 80, will be randomly selected by the Keno machine. Each
time the game is played, the player chooses 1 to 10 numbers (between
1 and 80) and the wagering amount. The Keno machine indicating
the winning numbers will then randomly select 20 numbers. The
objective is to have as many matches as possible between the numbers
chosen by the player, and those randomly selected by the machine.
The number of matches will be highlighted and a possible payout
will be rewarded based on the number of matches.
How To Play
Begin by depositing money into the Keno machine. To do this, you
must select a bill type (£100, £50, £20, £10,
£5) from the panel at the top right hand corner of the Keno
screen. You can toggle through the different bill types by clicking
on the panel. Once you have made your selection, deposit the bill
into the Keno machine by clicking on the bill deposit area. The
amount of coins within the Keno machine is based on the amount
deposited and the coin denomination selected and is shown in the
Credit field in the middle right hand side of the Keno machine.
For example, if you deposit £100 when the coin denomination
selector (ball in the top left corner) is set to £1, you
will see 100 coins in the Credit field.
Similarly, if you set the coin denomination
to £2 (by clicking the left arrow button), you will see
that the Credit field has changed to 50 coins. The Bet field displays
the amount of coins you have selected to bet that turn. Please
note that the Balance field will not change when you change the
coin denomination since they show your balance in dollars (not
coins). The player may select coin denominations of £0.25,
£1, £2, or £5.
Once you have deposited
money into the Keno machine, the next step is to place a bet using
the Bet or Bet Max buttons. If the Bet button is selected, 1 coin
will be bet per game while the Bet Max button allows for 5 coins
to be bet per game. Intermediate amounts (e.g. £2, £3,
and £4 per game) can be selected by pressing the Bet button
multiple times. Once the bet amount has been selected, you then
choose the 1 to 10 numbers you believe will be randomly selected
by the Keno machine. This is done by simply clicking on the desired
number in the Keno number grid. A number may be unselected by
clicking on the same number again. Once you have chosen between
1 and 10 numbers, you now select how many games you would like
to play consecutively with those selected numbers using the Play
One, Play Five, or Play Ten buttons. The Play One option plays
the game once, Play Five plays the game five times, and Play Ten
plays the game ten times consecutively.
Selecting either the Play One, Play
Five, or Play Ten buttons starts the game. The numbers randomly
chosen by the Keno machine are shown by a Keno ball landing in
the space of a particular number. Any matches with the player's
selections are shown with in flashing bright yellow. The payoffs
are dependent on the total numbers selected by the player and
the total number of matches.
