| HTG1395 3-in-1 LCD Game Features * * Operating voltage: 1.2V~1.5V 27 segment3 common, 1/3 duty, 1/2 bias LCD driver * RC oscillator 400kHz General Description HTG1395 is a 3-in-1 LCD game designed by HOLTEK. Customers can select three kinds of game by using 2 Pad Bounding options, namely; Car racing, Soccer and the Eagle Preys on the chickens. Each game has its own characteristics. Car racing has two kinds of game mode, GAME I and GAME II. Those two games have different number of cars. The longer the user plays, the speed increases. The Soccer game controls the movement of the goalie either to the left or to the right in an attempt to block the football. Contact with the cup that simultaneously appears at the upper left of the screen, could add 50 points to the score. When the opponent makes a goal, the score adds to three times and the game is over. The Eagle preys on the chickens is played by making the mother hen protect her young chicks from the attacks of the eagle.

A short demonstration game is played showing the battle between the attacking eagle and the defending mother hen who is trying to protect her chicks.

The remaining keys are disabled. - Upon pressing the START/PAUSE key once during the demonstration period or when a game finishes, the highest number of rounds achieved from the previous games are displayed on the right hand side of the screen, accompanied by a short fanfare. Next, the highest recorded score is displayed, again accompanied by a short fanfare. Next, the cumulative total for the coming game (1-1) is displayed, also accompanied by a short fanfare. Finally the current score for the first game will be displayed (0000). The game begins immediately upon display of this score. During the initialization period when the scores and performances are displayed, the keys are temporarily disabled. - The maximum number of rounds is nine. A round is divided into four innings. Each inning represents successive increments in the number of eagles attacking the hen, - - - - - - - - hence an increase in level of difficulty. The first inning represents one eagle attacking the hen. The second inning represents two eagles attacking the hen and so on. Each round represents successive increase in game speed. The first round is the slowest, the ninth round is the fastest. The player can use the arrow keys (L,R) to control the movement of the hen, or press the HIT key to attack the eagle. Each time a hen pecks an eagle to death, 10 points are awarded. If 15 eagles are pecked to death, the next game skips a set (it is not necessary to move through each innings consecutively). If neither the hen nor any of her chicks have been eaten at the beginning of a new inning, 50 points are awarded. The highest score is 9990. Once this score has been reached, no more points will be awarded. A round is achieved after four innings are completed. Nine rounds is the maximum number of rounds achievable. When all innings in all nine rounds have been completed, a new game will start from the beginning. If the eagle lands right on the hen, the demise of the hen is denoted by an X. If the eagle, upon reaching the ground, fails to eat the hen, the eagle remains motionless for a moment before disappearing. However, if the eagle lands on the chicks right, the chick will be eaten. An X denotes the demise of a chick. Once the hen and her chicks have all been eaten by the eagle three times, GAME OVER flashes on the LCD, accompanied by a little musical finale. The image will be frozen until START is pressed.
