Two versions of this game exist. In the the original version a routine that handled the additional on-screen balls in game 3 - 6 was missing a comparison and branch. This was included in the second version.
In the Progressive variations, when a brick progresses to the last row at the bottom center of the screen, it will stay there for a specified amount of time and then disappear. If you hit it in the center before it disappears, you may receive a special bonus of 50-150 points.
Multi-language boxes with a N sticker on the top flap containing a NTSC Black label cart are known to exist.
