All of the thrills of slot-car racing with none of the dangers!
See, the italics are what makes this link irresistably clickable. When you arrive at your destination, there you will find a blank screen, on which you can construct the slot-car track of your dreams. Assuming the slot-car track of your dreams fits on one screen.
It actually isn't bad. It would have been nice to be able to build bigger tracks, add scenery, etc., but whaddya want for free?
You control your car by clicking on its icon (or use the D or K keys) at the bottom. There are five selectable levels, of which 1 is the easiest.
Warning: Typical slot-car sounds. Also some voice offering inane commentary when your car flips off the track. I think it's meant to be humorous.
