Falco Lines 

Falco Lines is an enjoyable game in which you must move the colored balls to align five or more of the same color to make them disappear from the board. The balls can only be moved in a straight line, and only if there are no other balls blocking their way. The objective is to create as many lines as possible before the game is over. The thing is that every time you move a ball, others are added randomly, so it gets more and more challenging. The game is over when there are no more available moves or when the board gets full of balls.

Sadly, the game only includes one level, but it may last a long time, depending on your skills. All the games are timed, so you can break your own records. Unfortunately, the game only includes one mode, one difficulty level, and no customization options. Graphics are really simple, as well as sounds, and there is no music.

In short, Falco Lines is just a simple free game to pass the time which doesn't include much but at least it is enjoyable and challenging.
