Welcome to Asgard, the dwelling place of Gods. The God of Lightning, Thor, invites you to join him as he fights the big bad Fenrir Wolf. But don't worry. Thor's Mjolnir is with him, so you have a better chance of winning the fight against the wolf and getting the treasures of Asgard for yourself.
Aside from the powerful theme, Thor X is packed with cascading reels, meaning consecutive wins for you. Through the cascades, you can also trigger the free spins. Land more consecutive winning combos, and more free spins will be on your way. Land scatters, and you trigger another star bonus round, the bonus game. This is where the fight with the Fenrir Wolf actually happens. And if you don't want to wait for it to trigger spontaneously, you can use the bonus buy option to get access to the bonus round. So, if you follow me through this Thor X slot review, you will certainly find out how to get the most out of it.


The minute you launch it, the Thor X slot by TaDa Gaming takes you to Asgard, the Nordic mythological place where the Gods live. Thor himself appears on the screen, making his signature move with his magic hammer, the Mjolnir, getting ready for action. He prepares you for what's coming, a fight that decides who's the most powerful in the slot.
Fire burns on both sides of the grid, which is conveniently placed upon a temple door background. On the left side of the reels, there’s a pillar where consecutive wins are marked. It informs you how many more you need to trigger the free spins round.
Below the grid are the setup buttons, and behind them, you can see the Norse lands in the far, far distance. The audio is modestly playing in the background, with tunes that set you up for battle.
The consecutive wins not only bring payouts but also offer a chance to trigger the free spins. So, if you’re into the theme, you should definitely put it on your must-try list.
Press the coins button, found below the reels, and decide on your bet. The minimum bet you can place in the game is 12c, while the maximum is $180 for the 15 paylines across the 5x3 grid. Go a bit to the left and press the settings button to access the paytable as soon as you tap the “i” button.
Mjolnir is the wild, while the gates of Asgard are the bonus symbol. The former substitutes for all symbols bar the latter and gives the top payout. The latter only appears on the middle reels. Thor gives the same payout as the Wild, 1,000x for a 5-of-a-kind combo. Other theme-suited high-pays include an eye, the wolf, Thor's helmet, and horn, while the two low-pays are two Norse symbols, one blue, and one green.
Assuming you've decided on the bet level before you start spinning, continue reading to find out what to expect from the base and bonus rounds.
The cascading reel feature eliminates winning symbols from the grid upon a win, allowing new symbols to appear instead. Thanks to it, you get a shot at winning consecutive wins in one single spin, up to 100. These wins are marked on the left of the reels, and should you get 4, 5, 6, or 7, you win 4, 5, 10, or 20 free spins, respectively.
You can buy free spins access by pressing the buy bonus button for 80x the stake.
If, during the base game or free spins, you land 3 bonus symbols, you trigger the bonus game. During the round, Thor fights the wolf, starting with 3 chances/lives. If he gets attacked by the wolf, 1 chance is lost, and the bonus ends when Thor has no more chances. In each of the battles, you get to choose one of three options:
I tried the game for the max bet, and on the 8th spin, I managed to land consecutive cascades and triggered the five free spins. During the free spins, I wasn’t lucky enough to get more than three cascades to get more free spins, but I did manage to win a total of 13,6x the stake.
Unfortunately, I couldn’t manage to trigger the bonus game, no matter how many more spins I had to pay for. So, I cannot really share with you how it plays out. That was really frustrating and one of the cons of this game. The bonus game sounds good on paper, but despite all the efforts, I couldn’t get in, and that was a bummer.
Thor X online slot is medium volatile, with an RTP of 96.10%, which increases to 96.24% when you use the bonus buy option. The max you can win playing it is 300x the stake.
Thor X slot is exciting to play, there’s no doubt. In addition, the consecutive wins not only bring payouts but also offer a chance to trigger the free spins. So, if you’re into the theme, you should definitely put it on your must-try list. You can look it up across the best online casinos powered by TaDa Gaming.
Yggdrasil’s Thor Infinity Reels is as masterfully portrayed in terms of theme but also far more rewarding, though highly volatile. The 5,000x the stake payout potential in Pragmatic Play’s same-themed Power of Thor Megaways is also a great candidate. So, explore your options and go with the one that suits your playing style the best.
