The point of this game is to roll your ball (you toss it at the start line) from one end of the 'court' to the other end where the finish line is, missing or hitting different things that are in your ball's way.
First off, decide where your court will be. Create a start line (can be a ribbon, a pencil, a line drawn into the carpet with your finger, or whatever you have) and a finish line. Between the two lines, make obstacles for your ball to hit, miss, go over, bounce off, under, around--anything!
Some ideas--a toy horse could be a bridge and your ball has to go between the legs. Maybe a propped up comb needs to be knocked over, a toilet paper tube needs to be gone through. Put as much in your court as you want. Mix it up! Is it too hard? Make it easier. Too easy, make it harder!
When playing with a friend, have one person on each end of the court. So your finish line becomes their start line and your start line becomes their finish line.
The obstacle game can also be a 'points' game where you get points for hitting or missing different things in your court.
Make this a family activity: The more people working on the course, the cooler the ideas!
