PAC-ATTACK is a falling board puzzle game in which you have to cleverly line up and clear the dropping PAC-MAN, wall blocks and ghost. Get higher your score if you will clear more blocks at a time. Groups of 3 blocks will be dropped from top of the screen at once. Rows, that are full of wall-blocks, will disappear. PAC-MAN will come out as a block from time-to-time. Bear in mind that PAC-MAN moves by gravity toward the bottom of screen and will eat any ghosts in his path. When PAC-MAN eats enough number of ghosts, a fairy will appear. The fairy is able to clear all monsters of 8 lines below the line it lands on.
Avoid the blocks and ghosts from reaching at top of the screen by clearing wall blocks and eating ghosts. Initially, the play field of each puzzle is pre-filled by some ghosts and wall-blocks. Pre-determined blocks will be dropped and you have to arrange them such that PAC-MAN can eat all ghosts. This game allows you to compete against your Facebook friends within online-ranking mode named Scramble.
