I have (and have had) several of these Russian games before, and have seen the same thing on more than one of them... It's just whatever the green coating is being poorly made. Is it flaking off? If it is, and you remove it, the board looks fine underneath.
It might be something different on yours, but I've never seen liquid damage on a circuit board that didn't leave behind other evidence (corrosion, rust, residue from the liquid, etc...) I just made that comment as yours looks exactly like a couple of these 'Elektronika' games I've had in the past...

I'd say Sean's the best option though, send 'em his way. smile
