The player has to line up tiles in rows by sliding them around horizontally or vertically.
This game runs on Namco System 1 hardware.
It seems this game is missing data. The obvious title screen is know, however there is another issue that usually isn't mentioned. The girl from the bonus round has special separate picture that is shown when certain bonus rounds are completed. The problem is she is missing facial features when this picture of her is shown. This almost seems like chr 7 or obj 0 may be missing.
