Operational desc r i p tion
•
Right after the batteries are installed, the
system goes into the DEMO mode. The default game is BLACK JACK. By pressing the
START key, the game begins. And the money
to gamble with amounts to 2000 units. However, if activity has bee n suspen ded for more
than 2 minutes, power is automatically
turned off. To turn on the power, press the
ON/OFF key. The player can resume playing.
The mode remains the same as that before the
power was turned off. In other words, if the
power is turned off in the DEMO mode, this
mode is on the screen after the power is
turned on.
•
POKER and BLACK JACK have the same
betting strategies. First, the money to gamble
with is displayed and the symbol $ flashes on
the screen. Then, by pressing B ET_U (KEY5)
or BET_D (KEY4), the previous bets are
HT113RA
shown. The bet is incremented by 1 whenever
the BET_U (KEY5) key is pressed. On the
other hand, the bet is decremented by 1 whenever the BET_D (KEY4) is pressed. After the
bets have been made, pres s the DEA L key to
start dealing the cards. However, if the player
fails to press the BET_U or BET_D key, pressing the DEAL key restores the bet to the
previous one. The bet is pre-set to 1 if it is the
first time to lay the bet.
•
BLACK JACK
♦
BLACK JACK is one of the most common
games in casinos. The rules for this game are
quite easy. The player wins as long as his/ her
total score is greater than the dealer’s. However, the player loses the game when his/her
total score is over 21.
♦
The values of the cards 2~10 are scored
according to their corresponding face values. As for the cards J, Q, K, their values are
all scored as 10. Finally, the value of the
ACE card can be scored either as 1 or 11
depending on the player’s preference.
♦
After the bets are made, the dealer and
player are dealt two cards each o n the first
deal. The dealer’s first card is covered. So,
the player can only se e the dealer’s second
card. The following explains three conditions which may then appear:
–
DOUBLE
When the total val ue of the player ’s two
cards amounts to 1 1, (s)he may lay the bet
on one-more-card-dealt-only . However , the
player should lay the bet two times larger
than his/her present one. Such a bet is for
the player’s a dvantage, since (s)he is quite
likely to get the full score of 21 and win the
BLACK JACK game by holding a score of
11. As long as the total value of his/her
three cards is greater than that of the
dealer’s, the player wins the game and
gains the bet two times larger than
his/hers.

INSURANCE
When the dealer’s second card is an ACE,
it is quite possible that the dealer will win
BLACK JACK. In this case, the player
may pay half of the bets to buy insurance.
The dealer, if he wins BLACK JACK, will
refund all the bets to the player. If not, the
dealer will confiscate the 1/2 bets. And the
game goes on running.
–
SPLT
When the two cards held by the player have
the same value, (s)he may lay t he bet on any
one of his/her two cards. Nevertheless, the
player still has to lay another bet for the
other unbetted card.
When one or possibly two of the above three
conditions take place, the exact symbol,
namely INSURANCE, DOUBLE, or S PLIT,
will fla sh. At th is time , the pl ayer has the
choice of one or none of these conditions.
However, the player is not suggested to bet
if his/her money to gamble with is not sufficient for that bet.
♦
If there is no special case, pressing the DEAL
key deals the cards. However, when the
STAND (KEY4) key is pressed, no more cards
are dealt. The dealer can then deal additional
cards to himself. The rules are pretty easy.
The dealer is required to deal himself another
card if the sum of his current cards is less than
17. Otherwise, if the sum is 17 or greater, he
is not required to deal himself any more car ds.
♦
The various be tting rates of loss are listed
in the following:
BLACK JACK
(a score of 21 for two cards)
1.5
A score of less than 21 for 5 cards 0.5
A score of 7 for 3 cards 3.0
The player’s score greater than
the dealer’s
1.0

POKER (SHOW HAND)
♦
After the bets are made, five cards are dealt
by pressing the DEAL key. Below each card
is a HOLD symbol. The player may keep the
desired cards by pressing the appropriate
number of keys up to five keys. When the
cards are highlighted, it signifies that these
cards are to be reserved for betting. Otherwise, cards are to be re-dealt b y pressing t he
DEAL key. On the basis of the five card s,
the rates for winning and losing are cal culated in the following ways:
–
pair (jacks or better), 1 time
–
two pairs, 2 times
–
three of a kind, 3 times
–
straight, 5 times
–
flush, 8 times
–
full hous e, 35 times
–
four of a kind, 100 times
–
straight flush, 500 times
–
royal flush, 1000 times
♦
On winning, the player can obtain the score
by pressing the TAKE (KEY 5) key, and the
next game will start immediately. Or by
pressing the DOUBLE (KEY 4) key, the
big-or-small card value guessing game
comes into play. In this card value guessing
game, the card a t th e righ t m os t o f the five
cards is covered on the screen. The four
remaining cards are the same as those at
the previous four deals. The player may
press the BIG (KE Y 4) or SMALL (KEY 2)
key to guess that the value of th e covered
card is greater or less than 7. If 7 turns out
to be the score, the player wins no matter
whether his/her guess is greater or less than
7. The rate for winning is two times his/her
original bet whereas the player loses the
entire bet if the wrong guess is made.
