Whack-a-Mole

A "whack-a-mole" style game in which the player must use the fire and directional buttons to hit one of the four corresponding targets on the screen. The player loses if either he/she presses the wrong button, or taking too long to press. This game is variously known as "Hammer Attack", "Ghost Hunter" or "Alien Darts" in some packaging manuals. On the top of the screen, a symbol is used to represent the correct/wrong button press, usually "X" and "O", or in some version, a smile or frown.
