I've used many of the wonderful ppt games found here. 

In my current job, I don't have time to use them in class.

But, I'd like to offer them to students for self-study at home view my website.

But, I don't have the ppt skills to change the games here to work as single-player ones.

Do you know of any of the templates that work for single-player? 

Basically, I'm thinking of games that keep a running tally of points...

As a default, I can use the regular games I've used before, but it would be more engaging for the student if the game kept score...
