Build a wall around the edge of a big building plate.

Decide where the game is going to start and how to get the ball rolling (use the tubes and put them into a tower).

Build some obstacles for the ball to roll around or through.

Hold the base plate and roll the ball around – see if you can make it go slowly – can you make it go fast?

Where did you make the game start and end?

Can the ball roll uphill?

What happens if the tube turns up at the end? Does it slow the ball down?

Is it better to roll the ball quickly or slowly? Can you make it speed up or slow down?

Try making a scoring system – the difficult obstacles should have a higher score than the easy ones. Add flags or numbers to show the score, so that the players can keep track of their points.

Try making a tunnel out of DUPLO bricks or a bent piece of cardboard.
