Thunderstruck - what can I say about Thunderstruck except to say it's my favourite online slot and the grandfather of all free spin bonus slots. The great thing about Thunderstruck - and kudos to Microgaming for getting this right - is that it balances a decent amount of sizeable wins in normal play and the wins you get during the free spins, which can be pretty big. That's not to say it doesn't have it's cold moments mind, but when you get 3 or more of the orange "Scatter Rams" in view, the fun really begins...well, you hope it does anyway! Free spins can retrigger and you get 15 with all wins trebled when the Rams hit.

The online casinos above all carry the Thunderstruck slot on both the download and the Flash casino versions. You can also play it free by signing up a guest account at one of the online casinos listed above. This also gives you access to "Spring Break", "Summertime" and "Ladies Nite" which are exactly the same as the Thunderstruck slot in terms of features, but with different skins. I occasionally wander round to Spring Break when Thunderstruck is in a bad mood, but personally I find TS rules this genre.

On teh 4th May 2010, Microgaming launched the eagerly anticipated follow-up, Thunderstruck II - a very different slot but one that if you like the original, is well worth a try.
