Operational description
There are five levels in this game. Each level
has different shifting speed. The higher the
level is, the faster is the speed. When
START/ON key is pressed, the highest score is
shown and the initial level is displayed. Player
can press RFLIP to select the level. After that,
press START/ON key to start the game. Press
RFLIP to serve the ball, when the ball drops,
depending on its position press LFLIP or RFLIP
to flip the ball and prevent it from dropping to
the goal. The strength to serve a ball depends on
the length of time alloted in pressing RFLIP
key. There is a gate at the bottom left side of the
screen. The gate will open or close at intervals.
The ball should be prevented from dropping
down to the gate when it is open. There are only
three balls served in each level. When the score
reaches 3000 or 7000, one ball is relatively
added as bonus. When power is on, or player
has to select a level, or when the game is over, if
the player does not press any key at any one of
the three conditions, then it automatically goes
into free run within one minute. During free
run, if START/ON or OFF key is pressed, then
the game starts, or the power is off. Otherwise,
if the free run lasts about 4 minutes 20 seconds,
the power is automatically turned off. The high-
est score is lost only when RESET key is
pressed or when the battery is changed.
LCD test pattern
At any time, press LFLIP or RFLIP key simul-
taneously with RESET key, then release the
RESET key, all the LCD patterns are shown.
When LFLIP or RFLIP key is also released,
the program goes back to normal.
