Bubblins 2 is a free Match 3 online game: Arrange three or more same colored smileys in a row or column to remove them. The time is your only opponent, and you permanently have to remove a certain amount of Bubblins to keep the time indicator from reaching null. Also keep an eye on the big smiley on top right. When he's full a new harder level starts.
Click on a smiley, keep the mouse button pressed, and then drag the smiley left, right, up or down to change it with the Bubblin in that place.
