First, get all upgrades, then go after the BIG trophies, then just dig strait across, when you get the the big diamond depth and just send your mole out to get big diamonds. A very useful hint is that you can use your mole more than once, and you need to use him very often, then the hard badge shouldn't bee to hard after all. It's actually kinda like a hard-medium badge.......
I agree with buccio it does need badges,but all in all this a a wonderful game there is no doubt that it is better than the last one and deseves to given high praise. It it were a cd perhaps I'd buy it 5 out of 5 stars a 20 out of 10 absolutly the best I have come accross.
