Thoro Slot RTP, Details & Wager Limits
Like the Wild Toro slot, Thoro is played on 5 reels, 4 rows, and 178 paylines. You can hit a matching combination by landing 3 or more matching symbols on adjacent reels from left to right.
Bets range between 20p to £100 per spin. To adjust the stake size, tap the coins icon and select your preferred bet amount. Players outside the UK can switch up the gameplay by activating the Autoplay function to access up to 100 autospins.
I was disappointed with the Thoro RTP of 94%, which is lower than the average at UK online casinos. Although this means that the game will not make our best payout slots, the good news is that it has medium-high volatility. With this, you can expect the right balance between big payouts and a high frequency of wins.
This Norse-mythology-themed slot has a 23.1% hit frequency. Put simply, you will land a win after every 4 spins on average. The Thoro max win per spin is 10,000x the bet. You can achieve this by landing 12 Lightning symbols on the reels at any Thoro casinos where you play this game.
Theme – Thor Journeys Back to Asgard to Reclaim the Throne
Thoro is another addition to ELK Studios’ growing collection of Toro online slot games, which includes Wild Toro 2, Gladiatoro, and Toro Shogun. This time, however, it takes a detour to explore Norse mythology, where Thor, the god of thunder, is set to become the king of Asgard following his return from Earth.
As expected, Thor appears in the form of Toro, a bull-headed character who sends lightning bolts across the reels with his Mjolnir. The colourful grid is set among thick clouds, with a city with iron gates, presumably Asgard, in the background.
There is something satisfying about a Thor-centered slot with an epic, larger-than-life soundtrack that sometimes goes full heavy metal, especially when the graphics are sharp and the animations are amusing.
On the reels, low-paying symbols are represented by runestone writings, while the high-paying symbols are inanimate elements in the Norse tradition. See how the paytable looks below:
| Symbol | Payouts/Info |
|---|---|
 Blue Rune | 3, 4, 5 = 0.1, 0.2, 0.4x stake |
 Green Rune | 3, 4, 5 = 0.15, 0.3, 0.5x stake |
 Pink Rune | 3, 4, 5 = 0.2, 0.4, 0.6x stake |
 Red Rune | 3, 4, 5 = 0.25, 0.5, 0.8x stake |
 Horn | 3, 4, 5 = 0.4, 0.6, 0.9x stake |
 Pig | 3, 4, 5 = 0.6, 0.8, 1.2x stake |
 Goblet | 3, 4, 5 = 0.8, 1.5, 2.5x stake |
 Helmet | 3, 4, 5 = 1.5, 2.5, 5x stake |

Thoro Mobile
Thoro mobile slot was developed with HTML5 technology, so it is compatible with portable devices and desktop computers. It runs smoothly on iOS and Android devices at mobile casinos without distorting the game’s functionalities or high-quality graphics.
However, I prefer to play it in portrait mode since the spin button is conveniently reachable even if I have to move around while using my phone with one hand only.
Thoro Bonus Features
The Thoro slot game comes with 6 bonus features, including respins, walking wilds, and a unique Lightning symbol. For non-UK players, the provider has also added its distinctive X-iter where you can purchase your way into activating bonus features.
Lightning Symbols
The Scatter symbol, represented by a lightning bolt, triggers a bonus game. It doubles as a paying symbol, awarding a win when you land 4 or more on the reels. However, it can only land on reels 2, 3, and 4.
The payout amount is calculated as: the current stake x the corresponding multiplier on the lightning paytable, which is on the left side of the grid. Moreover, the values on the lightning paytable can be upgraded to higher payout levels when Thoro wields Mjolnir.
In addition to that, you can hit the 10,000 max win by landing 12 lightning symbols on the reels. Of course, it is no easy feat to achieve this—I could only land a maximum of 6 lightning symbols on a spin in over 300 attempts. Nonetheless, it is a unique and rewarding bonus feature.
Loki Respin
You can activate 1 Loki respin by landing 2 or more Loki symbols anywhere on the reels during the base game. During this round, the Loki symbols remain sticky on the reels, and additional Loki symbols award 1 extra respin.
However, I would have enjoyed this feature better if it offered more respins corresponding to the number of Loki symbols that land on the reels.
Thoro Thunder Strike
The Thoro Thunder Strike feature is a replica of Toro Goes Wild in Gladiatoro. It is triggered when Thoro and Loki symbols appear together on the reels. During the Thoro Thunder Strike feature, Thoro moves vertically and horizontally to knock out all the Loki symbols with his Mjolnir. As he moves on the reels, he leaves a trail of wild symbols behind and awards 1 respin for each step.
I love the idea behind this feature—it depicts the strained relationship between Thor and his brother, Loki, as depicted in Norse myths.
Mjolnir and Thoro
You can trigger the Mjolnir feature when the Mjolnir appears on the reels simultaneously with Thoro, making him pull the Mjolnir towards him. Thoro is a walking wild that awards respins as he moves leftwards, just as in Gladiatoro. However, it does not double the value of symbols it passes.
As long as the Mjolnir feature is active, Thoro can randomly upgrade the lightning paytable or increase his multiplier value.
Bifrost Bonus (Free Spins)
Like most new online slots, Thoro has a bonus free-spins game that you can activate by landing 3 or more bonus symbols. Bonus symbols are represented by lightning bolts, and they can only appear in reels 2, 3, and 4. It is noteworthy that free spins do not work during Thoro’s Respins.
I was lucky enough to trigger the Bifrost bonus after a little less than 50 spins, awarding 8 free spins. Even more interesting, I was able to activate the Thoro Thunder Strike on my first free spin.
X-iter (Not Available in the UK)
X-iter is ELK’s proprietary bonus feature that allows you to jump right into the bonus game. It is typically a bonus buy feature that you will find at the top slot sites.
Unfortunately, the X-iter feature is not available in the UK. Nevertheless, here is a breakdown of the available game modes and their costs:
- Super Bonus: The next spin activates the Super Bonus game, where the Lightning paytable starts the highest payout. Thoro also carries both Mjolnir and a multiplier, and it costs 500x the bet.
- Bonus Game: This purchaseable feature guarantees an entry into the bonus game. It costs 100x the bet.
- Mjolnir Feature: You are guaranteed to trigger the bonus feature of the same name, where walking Thoro wields Mjolnir. It costs 25x the bet.
- Loki Respin: The following spin triggers Loki Respins, and it costs 10x the bet.
- Bonus Hunt: It increases your chances of getting into a bonus game by 3x or more, and it costs 3x the bet.
Thoro Verdict – Interesting Gameplay With an Instant Win Symbol!
In terms of visuals, I have always been indifferent about the Toro series, and disappointingly, the Thoro slot didn’t offer the graphics immersive enough to change my perception. This doesn’t take away from the fact that the game has high-quality design and amusing animations.
Thoro might be just a bull wielding a hammer, but the game boasts an impressive selection of bonus features—the Thoro Thunder Strike feature and Lightning symbols stood out during the test run. It is rather fascinating that Thoro moves around during the Thunder Strike feature, activating respins and knocking down Loki off the reels.
Best of all, you can hit the 10,000x max win during the base game rather than attempting to achieve it in the bonus game. While Thoro may rank amongst ELK Studios’ best real-money slots, the 94% RTP is a major setback. For a well-rounded experience, I recommend you play the Thoro demo game, available on this page, alongside a ton of other free online slots.
