I think they're fine. I prefer a real ditionary with pages and stuff because it's easier to browse, but what is it that's bothering you? Just the fact that they might be playing games?

I've never seen anyone playing games with e-dictionaries in my classes. What king of games do they have? word games?

You could always define a time when dictionaries are allowed and when they're not. If they use the dictionaries to get their work done and play games after they've completed the exercise, it really doesn't matter. They got their work done, right? If they're not getting their work done then you need to initiate some sort of incentive or punishment system.

If they're playing games while you are teaching then I can see the problem and maybe you could fix that with a set 'dictionary time.'
