Marbles are not just for fun but also for training your mind. See if you still have the guts to play with marbles once you have tried Woodbox Marble Lines! Your goal here is to clear marbles either horizontally or vertically. You need to create 5 marbles of the same color in order to clear them out of the screen. Once you have cleared enough marbles, you will be able to access the next level. More marbles will also appear every time you move a marble, but they will only appear after 2 moves. The board will be filled up with marbles if you can't create lines so hurry it up!
