Thoro is a cheeky ELK Studios release where a cartoon bull cosplays as a Norse god. This 5-reel, 4-row game delivers 178 ways to win and a stack of inventive features: lightning strike instant prizes up to 10,000x, walking wild respins, Loki-triggered respins, wild trails, and two tiers of free spins, including a Super mode.
With high volatility and a 94.00% RTP, the Thoro slot caters to players who enjoy bold swings and feature-packed gameplay on desktop and mobile.
Thoro keeps the Toro universe’s playful tone: a grinning red bull (as Thor), a sly matador (as Loki), rune stones, foaming ale, roast pork, helmets, horns, and the mighty hammer. Asgard glows in the background while roars, commentary, and piano riffs set the mood.
Base wins pay for 3–5 matching symbols in sequence from the left. Sample values (at selected stake): blue rune pays 0.1x/0.2x/0.4x for 3/4/5; the helmet pays 1.5x/2.5x/5x for 3/4/5.
A lightning meter beside the reels holds nine prize tiers from 2x to 10,000x. Land 4–12 golden lightning bolts at once (bolts appear only on reels 2–4) to claim the corresponding prize. Thoro can randomly pull Mjolnir from reel 1 to upgrade meter tiers, raising the minimum prize from 2x → 5x → 10x (with higher tiers scaling up accordingly).
Land Thoro and Loki together to trigger a chase: Thoro dashes across the reels, leaving a trail of wilds and chasing Loki off-screen. The chase starts on any Loki on the same reel, then sweeps left (and right if more Lokis are visible).
If 2+ Loki symbols appear, they trigger Loki respins. Respins continue as long as new Lokis land, potentially covering large parts of the grid for a big finish.
The top payout is 10,000x your bet if all 12 lightning bolts land simultaneously on the three middle reels. At the 100.00 max stake, that’s up to 1,000,000.00.
The Thoro slot is a riot—sharp visuals, witty character moments, and layered bonuses that interlock in satisfying ways. The lightning meter gives clear instant-win goals, while walking wild respins, Loki chases, and upgraded Super Bifrost spins add real punch.
The 94% RTP is on the low side, so Thoro is best for players who value quirky, high-volatility features over long-haul return. If that’s you, play Thoro for a thunderous, high-energy session.
Thoro mixes Norse gods with Spanish bullfighting in a fun cartoon style. A red bull dressed as Thor is the star, along with the matador in his Loki outfit. Other symbols across the 5x4 grid include hammers, helmets, horns, and high card emblems.
Play the Thoro slot online, and you can win as much as 10,000 times the bet on any spin. It’s worth 1,000,000.00 at the maximum stake, and this prize is yours if lightning bolts fill all 12 symbol positions on the three middle reels.

You can trigger free spins of the Thoro slot reels when three bonus bolts of lightning appear at once. You get 8 Bifrost spins, or Super spins can be awarded at random. Lightning prizes are upgraded in the Super games, while Thoro will also trigger respins on each appearance.
