Thoro: Slot Overview

The online slot Wild Toro was one of ELK Studios’ better-known early titles, and after sitting quiet for 5 years it charged back onto the scene in 2021 as part of a 3-slot world tour that began with Wild Toro 2. Since then, the unruly star has gone toe-to-toe with bison in Buffalo Toro, taken in Japanese vibes in Toro Shogun, and battled it out in Gladiatoro. It’s like he caught the travel bug and decided to tick off destinations nonstop. Now Toro goes full Norse in the online slot Thoro, with the Matador along for the ride as Loki, plus a generous stack of extra features.

First up: Thoro. Yep, a neat mash-up of Toro and the legendary god of thunder, Thor. In this story, Thoro is poised to take the throne of Asgard, but his troublesome brother Loki has different ideas… Thoro runs on a 5-reel, 4-row grid, set in the cloud-borne realm of Asgard with the Bifrost in view. It’s a world away from the steamy Spanish arena of Wild Toro, yet the playful man-versus-beast face-off remains, along with a few familiar mechanics.

One way to land winnings in Thoro is by hitting matching symbols on adjacent reels starting from the left side of the grid. Symbols on neighbouring reels must connect either horizontally or diagonally to count as a win. Alongside five X-iter betting modes, players can set stakes from 20 c to $/€100 per spin in this medium-high volatile slot, which runs at an RTP of 94%.

Glowing rune stones make up Thoro’s 4 low-paying symbols, while a horn, a daggered pig, a cup of bubbly, and a helmet represent the higher pays. Five-of-a-kind rune hits return 0.4 to 0.8 times the bet; landing 5 matching premium symbols pays 0.9 to 5 times the bet. Wild symbols assist by substituting for any standard paying symbol to complete combinations. An all-wild combination pays the same as the top-paying symbol.

Thoro: Slot Features

Rumbling out of Asgard are Lightning symbol wins, Loki Respins, a Thoro Thunder Strike feature, a Mjolnir feature, free spins, super free spins, and X-iter bonus buys.

Lightning Symbols

Lightning symbols are required to claim rewards from the Lightning paytable shown beside the reels. Lightning symbols can appear on reels 2, 3, and 4. At the base level, landing 4 to 11 landed Lightning symbols awards 2x to 1,000x the bet. The Lightning paytable can also be upgraded to unlock bigger prize values. Hitting 12 Lightning symbols pays whatever amount is still needed to reach Thoro’s max win. Free spins scatter symbols count as Lightning symbols too.

Loki Respin

Landing 2 or more Loki symbols triggers a Loki Respin. During the respin, Loki symbols become sticky and stay where they land. If more Loki symbols appear on a Loki Respin, another respin is awarded.

Thoro Thunder Strike

Thoro acts as a walking wild that steps left until it exits from the leftmost reel, awarding a respin for each move. Only one Thoro can appear on the grid at any time. Lightning and scatter symbols are sticky during Thoro respins. Any Lightning symbol payout is only awarded once Thoro has spun out. Landing a Thoro symbol while at least one Loki symbol is visible, or landing a Loki while Thoro is in view, activates the Thoro Thunderstrike feature. In Thoro Thunder Strike, Thoro moves vertically and horizontally to smash all Loki symbols off the reels until none remain. As he charges and knocks Loki symbols away, Thoro leaves behind a trail of wild symbols.

Mjolnir

The Mjolnir symbol is a blocker that appears only while it hasn’t been pulled by Thoro. When both symbols show up, Thoro pulls Mjolnir towards him, which triggers the Mjolnir feature. In this state, Thoro carries Mjolnir and the Mjolnir feature stays active for the rest of the spin. Triggering the Mjolnir feature grants a respin provided Thoro Thunder Strike isn’t pending. While Mjolnir is active, Thoro can randomly upgrade the Lightning paytable or increase his own multiplier on each respin. If Mjolnir and Loki symbols are both present, Thoro pulls Mjolnir to trigger the Mjolnir feature before Thoro Thunder Strike.

Bonus Game

Scatter symbols land on reels 2, 3, and 4. Hitting 3 scatters starts the free spins round. Free spins are not decreased by Loki Respins or Thoro respins, and gameplay follows the same rules as the base game. In the super free spins bonus, the Lightning paytable starts at the highest payout level, and Thoro has both Mjolnir and a multiplier.

X-iter

Thoro’s X-iter bonus buy menu includes: Bonus Hunt – get more than triple the chance of triggering the bonus game for 3x the bet. Loki Respin – 10x the bet to guarantee a Loki Respin. Mjolnir Feature – 25x the bet guaranteeing walking Thoro carrying Mjolnir. Free Spins (100x the bet). Super Free Spins (500x the bet).

Thoro: Slot Verdict

It’s amusing that there was a five-year gap between the original Wild Toro and The Wild Toro World Tour. Since that comeback, Toro has popped up across a broad set of sequels. Even if the central character is largely the same—just dressed for different roles—the gameplay and feature sets tend to vary a lot. We’ve seen everything from ‘book of’ mechanics to a hold ‘n win, and now an instant prize-style 9 Masks of Fire setup. Still, some staples remain, and anyone who enjoyed Toro chasing the Matador and scattering wilds around the reels will find that familiar flavour again in Thoro.

That said, Lightning symbols and Lightning paytable rewards add a fresh twist. For instance, while Toro—sorry, Thoro—marches across the reels triggering respins, extra wilds, and even his own presence can become secondary to collecting Lightning symbols. It’s worth stressing that during respins, Lightning symbols and scatters (which also count as Lightning symbols) lock in place, potentially delivering a cash payout once the respins finish. Much like Mjolnir helps Thor overcome enemies, Mjolnir here is useful for raising Thoro’s multiplier and upgrading the Lightning paytable. The base prize values are solid, but the upgraded Lightning paytable levels are clearly where things get much more exciting.

Regardless of the paytable level, Thoro’s max win is 10,000x, and it can be collected by landing 12 Lightning symbols on the reels at any point. Along the way, players get the polished audiovisual presentation ELK Studios is known for packing into its releases. The mix of Norse mythology with pounding heavy metal suits Thoro perfectly, and it’s matched by an equally satisfying combination of gameplay elements.
