Which one is better, Thunderstruck or Thunderstruck II? It’s a legit question. Both are amazing slots from Microgaming. And, if not for the first, there would none of the second.

Despite your own feelings regarding either of the slot machines, undeniably Thunderstruck II became a bigger success than its predecessor.

Differences Between Thunderstruck and Thunderstuck II

thunderstruck 2 paylinesThere are big differences between the two. Instead of 9 paylines, Thunderstruck II is a 243-payline slot. Which also changes the play limits.

On Thunderstruck you could play $0.01 cent per line up to $2 per line. However, Thunderstuck II became much more expensive ($0.30 per spin minimum).

These differences may be a big part behind the difference in popularity of the series. Perhaps there are more players that like 243-paylines compared to 9-payline slot fans.

Especially when you consider that the graphics haven’t changed that much. Thunderstruck II does look better but only slightly. You could even say that the visuals were updated just so the players could tell the two slots apart.

Because the symbols also stayed very much the same.

But a much more likely reason why Thunderstruck II became a bigger success than the first edition. And it’s not what you think.

How to Make a Hit Slot: Secret Recipe to Thunderstruck II

Thunderstruck II free spinsIf you know both slots, you probably think that RTP made a difference. Return-to-player ratio increased from 96.1 percent to 96.6 percent!

But the truth is that Microgaming simply made a much better marketing decision. At the time, Microgaming’s biggest rival was NetEnt’s Starburst. Everywhere you looked there were 10 free Starburst spins.

So, Microgaming went bigger. They contacted the casinos and approved a 50 free spins Thunderstruck no deposit offer. And it worked like a charm.

Starburst 10 spins x 10 cents meant you get $1 in free value.
Thunderstruck II 50 free spins at 0.30 meant you are getting $15 in no-risk value.

Nowadays these 50 free spins Thunderstuck II offers are not as common as they already did their job. The offer produced thousands of loyal players. But you should keep an eye out because from time to time you can still find 50 no deposit free spins on Thunderstruck II (even on the original Thunderstruck slot.)
