One nice touch was music in the title screen - relatively rare at the time this game was released.

This is pretty average game. Perhaps This game is much better when you try to control your horses.

The original Intellivision box had a different layout for Horse Racing. Either that, or it combined content from the betting screen - which ended up with a different color scheme than the image below shows.

Prerelease Horse Racing Shot

There were also some variations of the 'Running Man' and Mattel logo on the back cover.
