A block-shifting/line-building puzzler challenging gamers to connect as many lines together as possible by moving set blocks with line parts on top. The basic Gunpey gameplay has square pieces, each containing a diagonal line, rising from the bottom of the screen toward the top. You move the pieces up and down, attempting to form a line from left to right. The panels then disappear. The game ends early if -- you guessed it -- the pieces reach the top of the play field.

For this portable version, Q Entertainment is placing its focus on an aspect that it has become well-known for: its integration of music into gameplay. With the DS version, each time you clear a panel, the game releases a sound. By lining up the sound with the background music, you can make your own music. The game also features new control aspects for the Nintendo DS touchscreen.
