Lightning symbols and Bifrost
Four or more lightning symbols pay a scatter win multiplied by the value of the Lightning paytable. This paytable can be improved when Thoro activates Mjolnir, and the official page specifies that 12 lightning symbols award the max win of 10,000x.
The Bifrost Bonus game is launched with 3 Bonus symbols visible. These Bonus symbols also count as lightning symbols, which explains why the bonus and the lightning logic are linked. During Thoro's respins, the Bonus and lightning symbols remain sticky.

Thoro, Mjolnir and Thunder Strike
Thoro acts as a walking wild: he generates respins by moving to the left. If he carries Mjolnir, he can improve the Lightning paytable or his own multiplier. The game thus keeps a clear thread: advance Thoro, lock important symbols, and look for a payout improvement.
The Thunder Strike feature is triggered when Thoro and Loki are involved together. Thoro then leaves a trail of Wilds while removing Loki symbols from the grid. This is the most spectacular part of the game, as it truly transforms the state of the board.
Point of Caution
The official RTP is not displayed directly on the public ELK page. Cross-references list it at 94%, with a low variant reported at 87%. It is therefore necessary to open the casino's information screen before playing for real money, especially if the operator offers multiple configurations.
X-iter allows you to get into the action faster, with 5 modes including a Super Bonus option at 500x. These shortcuts can be useful for testing features, but they significantly increase the risk per decision. The medium-high volatility and the 10,000x cap demand strict management of your bet.
Our Quick Opinion
Thoro is a great continuation of the ELK family centred around Toro: a central character, moving wilds, a prize ladder, and an X-iter option to choose your level of exposure. The sheet is especially of interest if you like slots that build a spin around an active wild rather than piling up mini-games.
To stay within the same ELK family, you can compare with Toro Shogun, Toro 7s or Tropicool. The slot machine page allows you to browse other games, and the best online casinos page helps to place the choice of game in the context of the operator.
