Pac-Attack is a puzzle game based on Namco's Japanese-only arcade puzzler Cosmo Gang the Puzzle . It is similar to many block-dropping puzzle games from the time, such as Puyo Puyo .
The objective of the game is to place ghosts and then, after three pieces (which can include one or two blocks as well), make Pac-Man eat as many ghosts as possible to try and clear up the game area. Pac-Man's directions are chosen at random between left or right, but as he goes moving on the game area (after you place him, of course), if he bumps against a block or a "wall" on the game area, he will change his direction.
The gameplay involves dropping blocks and ghosts onto the screen to try and clear up the game area. If a line of blocks and/or ghosts reaches the top, the game ends. However, by filling up a meter on the left of the game area, a fairy may appear that can clear approximately 6 or 7 lines with ghosts.
The game also features a versus mode against another human player, where the goal is to eat as many ghosts as possible and have your opponent receive many ghosts. Additionally, there is a Puzzle mode featuring 100 levels, where you must eat all ghosts with no more than 4 Pac-Men at least.
Pac-Attack was released on the Super Nintendo on June 15, 1905, and includes all of these gameplay modes.
