I've had a lot of success using PPT game templates from this site from when I was teaching in Korea.  I'm looking for something that is mobile-device friendly...?

First, though, do you know of a template or slides in PPT that automatically tallies scores?  All the templates I've used require the teacher to record the scores on a whiteboard or input them manually. 

I want something I can modify to fit vocabulary and/or grammar that students can access online - especially via tablet or smartphone - but I'd also like the PPT games to automatically keep score too.

I've been surfing the Internet.  I've seen game design sites where you can make simple side-scroller games as entertainment, but they don't look like they'd be good for adding teaching material...???....

I'm also a terrible artist.  Even if I had the time to design icons and images and backgrounds, they'd look like crap --- so I'm hoping to find a more novice game maker too...

I've come up dry so far...

Any ideas?
