General Description
HT1137A is a motorcycle LCD game designed by
HOLTEK. The race can run over straight or
crooked roads, exercising the players skill in not
only trying to overtake other contestants but in
negotiating severe turns at high speed. The exci ting game is sensational and gripping. This game
consists of nine major stages and each major stage
contains three minor stages. Each minor stage is
different. The first minor stage is normal motor-

cycle racing, in which the player needs to avoid
and overtake the opponent’s motorcycle. In the
second minor stage, the opponent’s motorcycle
will change lane in different directions at different time. At the third stage, the motorcycle is on
a slippery surface. The player’s motorcycle will
slip to the left or to the right. The direction
needs to be controlled so that collisions with the
other motorcycles is avoided.

Key description
•
START/ON
During power OFF state, pressing this key
turns on the power and starts the game. In the
power ON condition, pressing this key starts
a new game.
•
RESET
This key can be pressed at any time to reset
the game thus returning it to the starting
mode, and the highest score is cleared.
•
PAUSE
When the game is in progre ss, pressing this
key can temporarily stop the game. The
screen is frozen and all sound is muted. Press
it again, and the game continues. In the pause
condition, all keys are disabled except OFF,
START/ON, MUTE and PAUSE keys.
•
MUTE
This key switches the sound ON or OFF.
Sound is au tomatically on at reset or sta rt.
Press once to switch the sound off.
•
OFF
The power is switched off when this key is
pressed.
•
ACC
Relative to the current speed and present gear
setting, the motorcycle increases or maintains
its speed when the ACC or acceleration is
pressed.
•
BRAKE
Pressing this key can decrease the speed
quickly. If the ACC key and this key are
pressed at the same time, then the speed
gradually decreases.
•
Hi-Lo
In Lo gear , the hig hest speed is 150 kph. If, for
instance, you are riding at 100 kph and then
change to Hi, it’s possible to reach 300 kph.
However, if the speed drops below 100 kph
and you’re still in Hi gear, the speed will
gradually decrease to zero.
•
LEFT
Shifting to the left can balance the left bound
centrifugal force in a left turn so that the
motorcycle will not be thrown to the right side
of the road.
•
RIGHT
Shifting to the right can balance the right
bound centrifugal force in a right turn so that
the motorcycle will not be thrown to the left
side of the road.
•
RESET+ ACC+ BRAKE
Press all of these keys at the same time and
then release the RESE T key, all the patterns
will be shown.
Operational desc r i p tion
•
When START/ON is pressed, a prelude is
played and the highest reco rd and score are
shown. When “GO!” is displayed, the motorcycles are revved-up to start.
•
The time limit for each minor stage is 90
seconds. The higher the stage is, the more the
opponents appear on the road. Hence, the
player must avoid time wasting collisions and
reach the destination within the given time in
order to pass through to the next stage.

•
When the speed is higher than 100, press the
Hi-Lo key to change the low gear to high gear
up to 300 kph. If the speed is lowe r than 1 00
kph in high gear, the speed will gradually
decrease to zero.
•
During the competition, the player mu st constantly press the ACC key to maintain or
increase the speed, otherwise the speed will
gradually decrease. In high gear the speed
will decrease to 150 kph; in low gear the speed
will decrease to 0. When the speed is lower
than 100 kph, the player should avoid a collision because the speed is slow that the othe r
opponents will catch up with him.
•
When turning to the left or to the right, press
the opposite direction key to balance the centripetal force. Otherwise, the centrifugal force
will throw the motorcycle off the road.
•
The first and second minor stage is a chasing
contest in the road. The differen ce is that in
the first stage the opponent cannot change
lane as he/she wishes. However, in the second
stage lanes can b e changed. It increas es the
difficulty and preference.
•
The third min or stage is a contest on a s lippery road. The player’s motorcycle will slip
around so that direction control is important.
•
When one of the following five situations occur, player’s motorcycle will be destroyed so
the game needs to be restarted.
♦
Hit the front motorcycle
♦
Player is hit by the opponent from the back
♦
Wrong direction so the motorcycle is off line
♦
Direction control is not good, so the motorcycle is thrown off line by centrifugal force
♦
Player’s motorcycle collided while shifting
•
At each minor stage, the number of collision is
not counted.
Counting method
•
Beating the opponent: every win over an o pponent, 10 points are scored.
•
Bonus score: when a minor s tage is over, the
number of seconds left multiplied by 10 is the
bonus score.
