BG-Line is a background effect in Powder Game and Powder Game 2 that is similar to BG-air, except that BG-line has lines that show the direction of wind if it is present. It is the default BG upon starting the game, instead of the more likely BG-non. BG-line was the first background to be released in Powder Game in ver1.0, but it was not until ver 2.3 that is was called BG-line. Before that, it was simply the only background available.

In Powder Game 2, BG-line was implemented when the game was released in ver1.0 along with BG-non, BG-air, and BG-blur. It is still the default BG in Powder Game 2.



BG line

In uploads

In uploads, BG-line is used when it is needed to show the air pressure and the direction of the wind. BG-line is the most common BG (about half of all uploads use it). However, many people just use BG-line because it is the default background.

Glass viewing

If strong wind occurs, BG-line can be used to observe glass.

How BG-line works

BG-line is very similar to BG-air: high air pressure is shown green, and low air pressure is shown blue. The difference between it and BG-air is that wind is shown as a dark red line in BG-line, facing the direction the wind is blowing, and the more powerful the wind is, the longer the line is.

Pros and cons


  • Can show which area of the screen have high or low air pressure.
  • Can show what direction the wind is moving using red lines.


  • The red lines may look ugly or distracting to some people.
  • The red lines can hide the edges of the block if enough wind is present.
