The Gals Panic games are Japanese eroge, variants of the classic puzzle game Qix. The objective is to uncover the silhouette portion of background with a marker until at least 80% of the silhouette is uncovered. When capturing background, only the enclosed area without the stage boss is uncovered, so it is possible to capture 100% of silhouette without capturing the entire background, by limiting boss's movement to an area without silhouette.
As a sequel of Gals Panic , Gals Panic 2 has some new features includes 8-way joystick, stereo audio, and the Card Dispenser option.A stage begins with player at the edge of a randomly chosen rectangle. Capturing an area can no longer be done by moving cursor to the border of the background image.
The gauge is now changed to a time-based gauge, called time gauge. Time gauge is full at the beginning of a round or when player continues. When the gauge reaches below a certain point (as indicated by purple arrow), the background image changes, with time gauge drains in slower rate, until the image is changed back to normal.
