My son asked me to put together a website for him (he was seven at the time) with some statements about him and a few online games.

It was cute because he said "I am seven and this is my life, my best friend is Hugh and all boys should BEWARE of Eliza".

I found a number of good online games that gave you the code to put them onto your websites. There was also some free dirt bike games, here is one of them:

The game uses the arrow keys to control a dirt bike as it negotiates an obstacle course.

As you clear one section you move onto a more difficult section. You need to balance your forward movement as you go over obstacles with the body position of the rider.

As far as free dirt bike games go, this is a good one to play.
