I've now covered the summary, intro, graphics, music, and sound effects. Next on the list, I’m going to explore the key game features of 12 Bolts of Thunder.
At OLBG we create slot games reviews that include up-to-date info about essential features such as the theme, paylines and reels, bet range, and bonuses. I’ll finish off the review by talking about my play experience, first impressions and expert verdict.
Theme – Mythology
The game is based on Thor's magical hammer, which is called Mjölnir in case you're interested. Thor himself doesn't make an appearance in this game; however, it's set in some otherworldly realm - perhaps Asgard, where the gods in Norse mythology resided. As befitting of a game set in a place where Gods are supposed to hang out, the colours are based on the blues of the sky, and you'll see plenty of fluffy white clouds. 
When switching to the altogether different realm... of the Bonus Game, the colours switch to pink, purple and orange hues, which gives a glow to the screen. The grid is eye-catching with dazzling colours, and the Hammer Paytable matches this design, so you can't miss it. On the grid, in order of value from the highest, you'll see number 7s, the word BAR, a bell and a lucky horseshoe. These are then followed by the standard symbols of, A, K, Q and J.
Reels
The 12 Bolts of Thunder slot game is made up of 5 reels and 4 rows to play with.
Paylines
There are 20 non-adjustable paylines where you can trigger wins.
RTP
Return to Player is most commonly referred to as RTP which you may have seen on slot sites. This is a way of measuring theoretically what percentage of players' stakes will be returned to them over the long term so it's an important measure. The higher the number the better for players, RTP should be around 96% or more. 12 Bolts of Thunder is slightly over the average at 96.15%.
Thunderkick use this RTP figure as a default value so if you shop around you’ll discover different rates. To save you some time, we’ve identified a few at some of the current popular UK online casinos and added them to our table below.
By the way, RTP is just one factor when deciding which site to play at. You should also think about payment options, game library, customer support and welcome bonuses and deals. Our casino reviews look at this info and much, much more.

Play Experience & First Impressions
When launching the game for the first time it was aesthetically pleasing, but does it have the features to back it up? The gameplay is straightforward; the Hammer Paytable is key, so during the base game, you're hoping to see 4 or more Hammer symbols. A multiplier prize table is a tried-and-tested slot mechanic; you'll be familiar with it if you've played slots for a while. The Hammer Win during the Bonus Game made things a bit more dramatic and exciting due to the sheer amount of hammers popping up on the screen. However, the features felt a bit flat to me, it was a bit too simple.
