Marble Lines is an incredible bubble game. In the middle of the playing field, you see a small cannon standing. From this, you can fire different colored balls. There are balls in the colors red, yellow, blue as well as green. You always see the ball, which you can fire next, as well as the next ball. A path runs through the playing field, on which other balls in different colors move along. They are attached to each other in a seemingly endless queue. They move along through the field at a leisurely pace. Your task now is to bring three or more balls of the same color together. If you see two red balls move in a row, for example, you shoot a red ball at them. For this, you are aim at the balls with your mouse and shoot off your ball with a click of the mouse. If a group of three or more same-colored balls has now formed, the balls simply dissolve. The goal of Marble Lines is to shoot all the balls out of the game before they have reached the end of their path. All you have to have is a fast response as well as a really good eye. This game is also suitable for people with color blindness, because the balls are not only colorful, but also covered with various symbols, so that the colors are not important. With the space bar, you can change the color of the balls, which you want to fire away, by the way. So you will surely be able to shoot all the balls from the field of Marble Lines.
