I remember playing this at a casino also called "Black Diamond" around three years ago. It was the first time I had seen a "Top Game" casino and I remember thinking it was all a little strange, but I did appreciate the fact they had a download casino as browser based games didn't run anywhere near as well back then as they do today.
I also remember being shocked at just how badly the game seemed to pay - I left it running on auto play for a few hundred spins and saw the free spins being triggered numerous times with no real difference to my balance along the way. Looking at the paytable today it doesn't appear to be quite as low variance as I thought but I certainly didn't see any big wins whilst playing a couple of hundred spins as I wrote this review.
There are two features in this game, the free spins round I already mentioned which is triggered by hitting just two scatters but doesn't have any multiplier or infact any special features whatsoever, and a gold bar bonus round that awards between 40 and 200 coins - that's a maximum of just 8x your stake, hardly something to get excited about!
Some people have assured me that there are a few really great slot machines from Top Game, but I can honestly say I haven't managed to find one myself just yet. In all fairness I really don't get to play the games very much because I simply don't trust any of the casinos that run this software. The one time I did deposit at a Top Game casino I had my winnings confiscated and felt lucky to receive my deposit back, and I've not felt like I had a good reason to give them another try since then despite burning through a handful of no deposit bonuses trying out a few more of their games.
