12 Bolts of Thunder Slot Review
Get ready to witness the power of Thor in Thunderkick’s latest release, 12 Bolts of Thunder!
Harness the power of the God of Thunder in 12 Bolts of Thunder, where Multiplier Prizes of up to 30,000x are waiting to be claimed.
During Free Spins, each Hammer Win upgrades the paytable to reach new heights, meaning the smallest of Hammer Wins can end up quite rewarding!
12 Bolts of Thunder Base Game and Features
12 Bolts of Thunder is a 5-reel Video Slot with 20 fixed pay lines. Forming wins requires 3 or more of the same symbol types to land from left to right, starting from the leftmost reel.
12 Bolts of Thunder can be played for as little as £.€0.10 per spin, up to a maximum bet of £.€100 per spin, with plenty of other options in between the two. Thunderkick has opted for a theoretical RTP of 96.15% and a max win cap of 30,000x.
The highest-paying symbol here is the Triple 7s, followed by the Bar, Bell, and Horseshoe. Low-paying symbols are standard Ace, King, Queen, and Jack. Wilds substitute for all other symbols except Scatters and Hammer symbols.
Hammer Win Feature
To the right of the reel set is a list of 9 Multiplier Values equal to the number of Hammer symbols that can land. Hammer symbols appear on reels 2, 3, and 4 only.
When 4 or more Hammer symbols land at the same time, the Multiplier Value for the total number of Hammers in view is awarded, up to a maximum of 12 Hammers.
12 Bolts of Thunder Free Spins
Landing 3, 4, or 5 Scatters in the base game triggers the Free Spins round, awarding 6, 9, and 12 Free Spins respectively.
During Free Spins, Hammer wins will upgrade each Multiplier Value on the hammer paytable after each payout, up to a maximum of 5 Muliplier Upgrades. The highest Multiplier Value is 30,000x for 12 Hammer symbols at the highest level. Each Hammer win awards an additional +3 Free Spins.
12 Bolts of Thunder Bonus Buy
Those outside the UK will benefit from a Bonus Buy option. Thunderkick has granted players access to the Free Spins round for 100x your bet.
12 Bolts of Thunder: Our Verdict
After all that heat in Hot Potato! and Hellapenos, Thunderkick are taking us high in the sky for some fresh air and electrifying entertainment in their latest release, 12 Bolts of Thunder.
It’s rather strange to see a game represent a powerful God such as Thor, yet you never actually catch a glimpse of him anywhere. What also feels slightly out of place is the mix of classic fruit machine symbols. Who’d have thought Thor was a big fan of old fashioned fruit machines?
The hammer collection feature seen here looks like something from a Games Global slot, but like Push Gaming and 10 Swords, Thunderkick has put their own unique spin on it that can be witnessed in Free Spins.
Gameplay is nice and simple and it doesn’t take players long to figure out how the game works, but for players who thrive on quirky, complex features and big mechanics, you may find 12 Bolts of Thunder a little bit of a buzz kill.
The alterations made to the Hammer collection feature in Free Spins did come as a pleasant surprise. Each Hammer win during this time will cause the hammer paytable to upgrade, reaching up to a staggering 30,000x for 12 Hammers and triggering an additional +3 Free Spins.
Like most slots that have this kind of feature, it’s not always easy to see any action past 4 or 5 Hammer symbols. However, reaching Upgrade level 5 will see the minimum number of Hammers pay an impressive 50x your bet.
All in all, 12 Bolts of Thunder isn’t Thunderkick’s best work, but it did bring a spark of excitement in the Free Spins round!
12 Bolts of Thunder will be available at our favourite new slot sites when it releases on 30/01/2024!
