In Mixed Up, you have to straighten the lines out from the tangled web they have weaved. You start with two red lines that are intersecting. Click and drag at the end of any line to move it. You need to get it to the point where no lines are touching or intersecting at all. When a line doesn't touch any other lines, it will turn tan instead of red. When all the lines are tan, the level is over. The game gets harder when all the lines aren't separate. They might stay in shapes, which means you have to use a little bit more strategy in how you untangle the lines.
