12 Bolts of Thunder: Slot Overview

In the crowded landscape of online slots, the mechanic of landing specific symbols to unlock a range of prizes has become quite familiar. Thunderkick, joining the fray, introduces its own twist with “12 Bolts of Thunder,” a game that hints at its electrifying theme right in its title. The aim of the game is straightforward: accumulate as many Hammer symbols as possible to rake in cash rewards, with the free spins round promising prizes significantly larger than what’s typically seen in similar games.

Initially, “12 Bolts of Thunder” might not strike players as particularly groundbreaking. The Hammer Paytable, which outlines the available prizes, and the overall visual experience may not dazzle at first glance. The setting, amidst drifting clouds, doesn’t rank as Thunderkick’s most inventive backdrop. However, the game gains momentum as it unfolds. The free spins round is bathed in a warm golden hue, enhancing the visual appeal, complemented by a rainbow effect that signals the transition from the base game to the free spins. This, along with a well-chosen soundtrack, enriches the gaming experience, making “12 Bolts of Thunder” more engaging as players delve deeper.

In “12 Bolts of Thunder,” players can adjust their bets from a minimum of 10 cents to a maximum of $/€100 for each game round. Those eager to dive directly into the action will appreciate the bonus buy feature located next to the spin button, offering instant access to the bonus round. This option is particularly appealing as the Hammer prize ladder, central to the game’s reward system, can be significantly enhanced during the bonus round, making it an attractive target for players. The gameplay unfolds on a classic 5-reel, 20-payline layout, promising a high maximum win potential that complements the game’s high volatility and a solid Return to Player (RTP) rate of 96.15%.

The symbol assortment in “12 Bolts of Thunder” combines mythological elements with traditional slot motifs. The lower-value symbols are represented by the J to A card ranks, with a five-of-a-kind (5 OAK) hit ranging from 1.5 to 3 times the player’s bet. The higher-value symbols feature iconic slot imagery, including horseshoes, bells, BARs, and triple 7s, where landing five matching premium symbols can yield wins from 5 up to 20 times the bet. The wild symbol plays a pivotal role, substituting for all symbols except for the scatter and Hammer symbols, further enhancing the game’s dynamic and potential for big wins.

12 Bolts of Thunder: Slot Features

For players familiar with games that utilize scatter prizes, “12 Bolts of Thunder” offers a comfortable and engaging experience with its Hammer Wins, free spins, and a buy feature designed to enrich gameplay.

Hammer Win The game features Hammer symbols that can land on reels 2, 3, and 4. Securing at least 4 Hammer symbols triggers a payout based on the number of Hammers present and their position on the Hammer prize ladder. In the base game, the rewards for landing 4 to 12 Hammers range from 2x to 1,000x the player’s bet, accordingly. The free spins round offers the opportunity to enhance these values further on the Hammer Paytable.

Free Spins Landing 3, 4, or 5 scatter symbols awards players with 6, 9, or 12 free spins, respectively. During the free spins, any Hammer Win not only awards a payout but also elevates the Hammer prize ladder, increasing the prize values. The ladder can advance up to five levels, with the pinnacle awarding a staggering 30,000 times the bet for hitting 12 Hammers. Additionally, each Hammer Win grants 3 extra free spins, though the prize ladder resets once the player returns to the base game.

Buy Feature For those looking to directly access the free spins round, the game offers a buy feature at the cost of 100 times the total bet. Opting to buy free spins enhances the RTP to 96.5%, making it an attractive option for players aiming for the higher potential wins available during the free spins.

12 Bolts of Thunder: Slot Verdict

Amidst the electrifying theme of “12 Bolts of Thunder,” featuring thunder and hammers, one might expect the legendary Thor to play a central role. However, his absence is noticeable and somewhat mirrors the game’s initial visual impression, which leans towards the simplistic side. Yet, there’s an undeniable Thunderkick quality to the graphics—vibrant and crisp. The soundtrack and animations add a layer of engagement, ensuring that the experience is far from mundane, unlike the stark commentary offered by Jens Haaning’s provocative art piece “Take the Money and Run” at the Kunsten Museum of Modern Art.

For enthusiasts of games like “9 Masks of Fire” who crave a bit more excitement, “12 Bolts of Thunder” offers an intriguing proposition. Despite Thunderkick’s reputation for being conservative with its max win payouts, the prospect of winning up to 30,000 times the bet in this game is an enticement that’s hard to ignore, especially when compared to the more modest max wins of similar games from other developers. For instance, Push Gaming’s “10 Swords” caps its winning potential at 5,000x the bet, catering to a different kind of player with its lower volatility.

“12 Bolts of Thunder” appears to target gamblers who relish a more challenging gameplay experience, promising greater rewards for those willing to navigate its turbulent path. With its straightforward visuals and uncomplicated rules, the game aims to satisfy players looking for a scatter prize game that offers a level of excitement and challenge above the ordinary.
