This game is as easy at it looks. This game is also as hard as it looks. It’s called BallTrap and is from urgames.com (so don’t forgot to stop over and pay them homage).
The object is to get all the red balls on the red side and the blue balls on the blue side. You vertically move an opening between the two sections trying to organize the balls into their rightful places. This will get very difficult very quickly. Good luck!
