12 Bolts of Thunder Slot by Thunderkick: Free Demo & Game Review 2024

12 Bolts of Thunder Review

Thunderkick has finally decided to jump on the instant scatter prize bandwagon, arriving more than fashionably late to the party with 12 Bolts of Thunder slot. As is usually the case with volatile Thunderkick releases, the base game can be a rough ride through scarce payouts and smaller wins. The instant hammer prizes top out at 1,000x in the base game, which is unusually low for this genre.

However, the somewhat lackluster base game is compensated by a solid bonus round, where you can upgrade the hammer prizes up to 5 times. Each upgrade gives you extra free spins, and the top prize at level 5 is a solid 30,000x your stake. Each hammer prize win equals an upgrade, and getting at least a few of them didn’t seem that hard in our experience. 12 Bolts of Thunder is a fast-paced game that could’ve been more balanced, but the thrilling “hammer time” bonus round makes it worthwhile.

Thunderkick - Slot Developer

Thunderkick is a Swedish developer that’s been producing innovative and high-quality slot games since 2015. They are known for making game concepts their own by adding creative twists and tweaks, and they deliver visually pleasing and engaging games most of the time.

Slot Theme And Storyline

You get a bright and mood-lifting Norse mythology theme in 12 Bolts of Thunder slot, but Thor is nowhere to be seen in this game. You’ll probably don’t mind too much when his hammer wreaks havoc to the tune of up to 30,000x though, and the 5x4 grid is set against a cloudy backdrop. Not the most imaginative Norse theme we’ve seen, but still pleasant enough for a simple game like this.

12 Bolts of Thunder RTP, Volatility, And Max Win

The top-tier 12 Bolts of Thunder RTP of 96.15 % is well above average according to our stats, but keep in mind that this game comes with lower RTP settings as well. This is a highly volatile release from Thunderkick, so your bankroll will experience ups and downs in longer sessions. The 12 Bolts of Thunder max win is 30,000x your stake, which is well above average according to our numbers.

12 Bolts of Thunder Rules And Gameplay

You can play with bet levels of €0.1 to €100 per spin in 12 Bolts of Thunder, and the game plays out on 5 reels with 4 rows that add up to 20 paylines. You win by landing 3 to 5 matching symbols across at least 1 payline, and the Wild symbol substitutes for any pay symbol to help you out in that regard. The wild does not hold any value of its own, and scatters trigger the bonus round. Check the paytable below for details.

12 Bolts of Thunder Bonuses And Special Features

You can land instant hammer prizes up to 1,000x your stake in the base game, but other than that 12 Bolts of Thunder slot does not come with any bonus features except the bonus round where you can upgrade the prize table. Let’s check it all out!

Hammer Win

You can land hammer symbols on the 3 middle reels, and you need at least 4 hammers in view to win an instant prize. The prize table is on display on the right-hand side, and your hammer prize gets better the more hammers you land in view. The base game prize range goes from 2x to 1,000x your stake, and the top prize is won when you land 12 hammers in sight.

12 Bolts of Thunder Free Spins

You trigger the Bonus Round when 3, 4, or 5 scatters land in view, and this awards 6, 9, or 12 free spins, respectively. Every instant prize hammer win you land in the bonus round levels up the prize table with higher prizes across the board. You can upgrade the prize table 5 times, and each upgrade awards +3 extra free spins. At level 5, the top prize for 12 hammers in view pays 30,000x your stake.

12 Bolts of Thunder Bonus Buy (not UK)

Eligible players can purchase the bonus round for 100x the stake, and this increases the RTP to 96.5 %.

The 200 Spins 12 Bolts of Thunder Online Slot Experience

The base game didn’t land us much, but you get a brief taste of it anyway. We purchase and trigger the bonus round with 3 scatters at 0:48 into the 2:35-minute highlights video, which gave us the minimum of 6 free spins for starters. You can see which hammer prize level we achieved, and how much we got away with, by hitting the play button below.

Review Summary And Verdict

It’s actually refreshing to play a Norse mythology slot without some humanized, ripped deity hanging around the grid. Thor’s absence makes him omnipresent in a way, while his hammer can do serious damage in the bonus round. The 9 Masks Of Fire source of inspiration is undeniable, of course, and it’s a bit of a dilemma that the hammer prize max win is only 1,000x your stake in the base game. This makes 12 Bolts Of Thunder game less attractive in many ways, but it makes up for this shortcoming when the bonus round hits.

The main lure of instant scatter jackpot games is the possibility of larger payouts striking like lightning from a clear blue sky. The good news is that it didn’t seem that hard to level up the prize table in the bonus round, and we got plenty of extra spins via this upgrade system as well. Getting to level 5 will not happen every time, of course, but solid payouts are available from level 3 and up. This is a volatile game, however, but well worth checking out if you can stomach the barebones base game.
