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 hig h speed. The exc it-
ing game is sensational and gr ipping. This gam e
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 differ-
ent 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.

Functional Description
Key de scription
•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 progress, 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,
ST ART/ON, MUTE and PAUSE keys.
•MUTE
This key switches the sound ON or OFF.
Sound is automatically on at reset or start.
Press once to switch the sound of f.
•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 highest s peed is 150 kph. If, for
instance, you are riding a t 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 rel ease the RE SET key, all the pattern s
will be shown.
Operatio na l de sc r ip t ion
•When START/ON is pressed, a prelude is
played and the highest record and score are
shown. When “GO!” is displayed, the motorcy-
cles are re vved-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 coll isions and
reach the destination within the given time i n
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 100
kph in high gear, the speed will gradually
decrease to zero.
•During the com peti tio n, the player mu st con -
stantly 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 p layer should avoid a colli-
sion be cause the speed is slow that the othe r
opponents will catch up with him.
•When turn ing to the l eft or to the right, press
the opposite di rection key to balan ce the cen-
tripetal force. Otherwise, the centrifugal force
will throw the motorcycle off the road.
•The first and second mi no r stage is a chasing
contest in the road. The difference is that in
the first stage the opponent cannot change
lane as he/she wishes. However, in the second
stage lanes can be changed. It increases the
difficulty and preference.
•The third minor stage is a contest on a slip-
pery road. The player’s motorcycle will slip
around so that direction control is important.
•When one of the following five situations oc-
cur, 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 motor-
cycle is thrown off line by centrifugal force
♦Player’s motorcycle collided while shifting
•At each minor stage, the number of collision is
not counted.
Count ing method
•Beating the opponent: every win over an op-
ponent, 10 points are scored.
•Bonus s core: when a min or stage is over, the
number of secon ds left multiplied by 10 i s the
bonus score.
Soun d effe cts
•Brake sound
•Low gear driving sound
•High gear driving sound
•Collision sound
•Brushing past the opponent
•Counting sound for start
•Starting music (prelude)
•Pass-through music
•Game over music
•Slip sound
•Wrong gear sound
