12 Bolts of Thunder Slot Review

Overview

As mentioned in my introduction, 12 Bolts of Thunder comes to us from the inventive creators at Thunderkick Games. This Swedish developer has impressed me before with enjoyable titles like Pink Elephants, so I had high expectations for their take on Norse mythology slots.

The theme revolves around the legendary Viking god Thor, specifically his mighty hammer Mjolnir which can summon lightning and thunder. Symbols include items from Norse legend like winged helmets, drinking horns, and shields alongside classics like sevens and bells.

With 5 reels, 3 rows, and 20 fixed paylines, the layout sticks to a tried-and-true formula. The real innovation comes from the Hammer Prize mechanic, where landing stacks of hammer symbols triggers instant payouts based on the multiplier ladder shown on the right side of the screen.

During free spins, won by hitting 3+ bonus door scatters, the hammer prizes increase each time you hit a new threshold. At max level, landing 12 hammers can reward an earth-shattering 30,000x your wager! Talk about unleashing the thunder!

With an RTP of 96.15% and high variance, 12 Bolts of Thunder is best suited for daring players chasing those mega payouts. The simplicity of the core gameplay makes it accessible for all, while the huge win potential adds an electrifying jolt of excitement.

My Thoughts Overall

Over my many hours and 1000+ spins with this game, I'm pleased to say 12 Bolts of Thunder exceeded my expectations and left me thoroughly entertained. As an experienced slot enthusiast, I'm not easily impressed, but this release hit all the right notes.

The first thing that struck me was the cheery, inviting graphics. Slots based on Norse mythology and legends can sometimes end up looking too dark or gritty. Here, the friendly clouds and rainbow colors make the world feel magical instead of menacing.

The jaunty soundtrack also stood out right away for enhancing that lighthearted feel. I usually listen to podcasts or music while playing slots, but this score works perfectly fine on its own to accompany the action.

Of course, graphics and audio only go so far if the gameplay itself isn't up to par. Thankfully, 12 Bolts of Thunder delivers a smooth, rewarding experience. I love how straightforward and intuitive the main mechanics are while still retaining the potential for exciting wins.

The Hammer Prize multiplier ladder effectively replicates the anticipation of picking prize doors, chests, or other reveal-style bonus features. Since the hammers can strike on any spin, it adds an element of surprise.

As my session progressed, I was impressed by how the hammer payouts synergize with the free spins. Watching the prize values increase with every milestone kept the energy high throughout my time with this game. By the end, I really felt I had joined Thor on an adventure!

Overall, 12 Bolts of Thunder provides dynamic and satisfying entertainment through and through. For players seeking epic rewards wrapped in an accessible package, this game is a quest worth undertaking.

Bonus Features

The main draw of 12 Bolts of Thunder, as evident from the title, comes from the hammer symbol and its associated prize feature. Let's break down how it works:

Hammer Prize

During the base game, the hammer symbols can appear stacked on reels 2, 3, and 4. Whenever you land 4 or more hammers simultaneously, the game pays out an instant prize based on the Hammer Paytable.

This ladder starts at 2x your bet for 4 hammers, and increases all the way up to a whopping 1000x your bet if you hit the maximum of 12! Since the hammers can strike on any spin, it adds an unpredictable thrill to the gameplay.

Free Spins

Landing 3 or more of the scattered Bonus Door symbols will activate the free spins round, awarding 6 to 12 gratis games depending on the number that triggered.

The hammer prizes really amp up during this round. Each time you pass a hammer symbol threshold, the multiplier values on the paytable increase. After 5 upgrades, the top prize for 12 hammers becomes an incredible 30,000x!

This creates huge win potential as even smaller hammer hits can get multiplied into massive payouts. Plus, every hammer win grants you 3 extra spins, allowing the excitement to continue.

Bonus Buy

For a set fee, players can instantly buy their way into the free spins round. This is an ideal option if you're impatient to trigger them organically and want quicker access to those juicy hammer payouts.

Win Potential

As a fan of slots with high volatility and epic win possibilities, 12 Bolts of Thunder ticked all my boxes. The hammer prize mechanic and multiplying values during free spins create the potential for absolutely giant payouts.

As mentioned earlier, the top base game reward caps at 1000x your wager if you're lucky enough to land 12 hammer symbols at once. But the real magic happens in free spins, where the paytable can be upgraded 5 times.

At max level, a full stack of 12 hammers awards an earth-shattering 30,000x your stake! Even at mid-tier hammer levels, you can still win thousands of times your bet thanks to the multipliers. Hitting lots of extra free spins from the hammer wins extends the lucrative fun.

While the default RTP of 96.15% means you should expect to lose a few spins overall, the sheer size of the top prizes here more than makes up for it in my opinion. When you consider that many slots cap out between 500-1000x wins, the potential on this game is extraordinary.

Of course, keep in mind that max payouts are incredibly rare. But that's the thrill - knowing any spin could unleash a thundering hammer strike and change your fortunes in an instant! This is a slot built to create millionaires.
