The microgaming slots run real hot and real cold. Thunderstruck is a perfect example of this. Lately when I've played it, the rams have been off grazing or something and simply refuse to show up in other than a single cameo appearance. However, I got a nice bonus offer from Vegas Joker over the weekend and took them up on it, and decided to have some fun with it on T-struck for a while. It played almost predictably, after about 50 spins or so, I'd hit 3 rams and make back about 125% of what I lost before the free spins. Wasn't hitting anything big during the spins, but not bad either. So after 3 or 4 of these patterns repeated, I upped the ante from 5cents to 10cents per coin and sure enough, the pattern continued and the first round of free spins got me +$100 on my bankroll. Pretty good, so I continued at this level and almost predictably got my 3 rams again and on the 7th free spin, hit the combo you see below (its a little fuzzy because I actually did the screen capture after I got over the initial shock and the reels are just starting to spin, lol) Check out the feature wins amount in the lower right corner, not bad on a $4.50 bet. Cashed out almost immediately thereafter at +1500 over my deposit. Now that was fun.
