Players outside the UK can opt for Autoplay which allows up to 100 auto spins with loss and single-win limits. There is no Turbo Mode or Quick Spin setting.
Returns-wise, the 21 Thor Lightning Wayz RTP is 96% which is the same as the online slots average rate. With a 94% RTP version available, the volatility is in the high category (5/5). The hit frequency rate is 28.57% meaning a win every 3.5 spins.

Theme: unleash the god of thunder’s might
With a Norse mythology theme, the 21 Thor Lightning Wayz slot sees you unleash the might of the God of Thunder. In case you’re wondering, that’s Thor. He was a hammer-wielding god that has inspired many online slot games including Games Global’s iconic Thunderstruck 2 slot.
On first impressions, the artwork and imagery are top-drawer with high-definition graphics and animations. Set in an icy Asgard, there’s a thunderous sky forming the backdrop which sets the tone. With Thor standing to the side of the reels wielding his hammer, the soundtrack is calm yet stirring. There are also sounds which remind me a of land-based casino by WMS whenever you get winning combinations.
On the reels, you’ll see lightning-wrapped A, K, Q, J and 10 royals. Higher-value symbols including a drinking horn, crossed axes, longships, Asgard, a female warrior and Thor himself. Thor is the best-paying symbol awarding 1, 2, or 5 times your total bet for 3, 4 or 5 in combination.
Then you have the Mjölnir Wild symbol which is the hammer of the thunder god Thor. As expected, it substitutes for all symbols except the Shield Bonus Scatter. When 3 or more of the latter appear simultaneously, you’ll play the Thunder Free Spins feature.

21 Thor Lightning Wayz Bonus Features
The 21 Thor Lightning Wayz slot comes with a quartet of bonus features. Lightning Ways add win multipliers up to 100x to wins with Thor randomly appearing in the base game to add new Lightning Ways. In the Thunder Free Spins feature, you’ll play with higher Lightning Ways win multipliers if you trigger the feature with more scatters. When you get a Lightning Ways win, the win multiplier increases for future wins.
Lightning Ways feature
Every base game spin has 1 or more active Lightning Ways. Basically, every win on a Lightning Way will award a win multiplier. Called the Lightning Ways feature, the value of the win multiplier varies between 5x and 100x. These are calculated from left to right starting from the leftmost reel.
Lightning Strike feature
Randomly, Thor can create new Lightning Ways at any time during a base game spin. Known as the Lightning Strike feature, every Lightning Way that Thor creates will have a random win multiplier between 5x and 100x. New Lightning Ways lines disappear before the next spin begins.
Thunder Free Spins feature
The 21 Thor Lightning Wayz slot comes with a Thunder Free Spins feature. It’s triggered when you land 3 or more Shield Bonus Scatter symbols anywhere on the reels. 3, 4 or 5 scatters will award 15, 20 or 30 free spins respectively.
The more triggering scatters, the higher the starting win multipliers will be for Lightning Ways. With extra Lightning Ways in play, they are awarded at the beginning of the feature. After any win involving a Lightning Way line, the win multiplier on that Lightning Way increases by 1 for future wins.
With Thor randomly creating new Lightning Ways, 3 or more scatters will award 5 additional free spins, up to 70 free spins.
Buy feature
Players outside the UK can opt for the Buy feature. Enabled by clicking/pressing the ‘Buy feature’ button, you have 4 options. 3 of them will award you with free spins and 1 of them gives you 1 spin with random Lightning Ways:
| 50 x bet | 15 Thunder free spins |
| 100 x bet | 20 Thunder free spins |
| 150 x bet | 30 Thunder free spins |
| 25 x bet | 1 spin with random Lightning Ways |
21 Thor Lightning Wayz Review Summary: the only thing missing is the win potential
Aesthetically, the 21 Thor Lightning Wayz slot is superb. The high-definition imagery is amazing which is what we’ve come to expect from a 4ThePlayer game. Norse mythology-themed slots are popular but I think this one is probably the best-looking of them all. It’s particularly impressive using Big Reel Portrait Mode on your smartphone.
In terms of the gameplay, it’s pretty simple. There are Lightning Way paylines on each spin which applies a multiplier up to 100x when a win lands on the payment. Thor can help you randomly in the base game to create new Lightning Ways for a higher chance of winning.
In the Thunder Free Spins feature, triggering with 4 or 5 scatters will result in higher starting win multipliers for the Lightning Ways. The bonus feature hit frequency is 1 in 232 spins.
Harder said than done, wins on a Lightning Way line will see the multiplier increase by 1 each time. Enough wins can see high multipliers on Lightning Way lines, up to 100x. Winning extra free spins is the key to building up those Lightning Ways multipliers though.
I’m sure that 4ThePlayer will be using Lightning Ways again. It’s similar to the SuperSpinner multipliers found in Print Studios slots like Darkness and Royal Potato 2.
That said, the win potential of 1,500 x bet is a tad disappointing. Especially when you compare it to the 90k Yeti Gigablox slot that comes with 90,000 x bet max wins! Another option is the ancient Egyptian-themed 4 Secret Pyramids which offers 55,000 x bet max payouts.
All in all, the 21 Thor Lightning Wayz slot is great to look at and the gameplay is exciting. The max win potential does let it down but it’s still decent enough to warrant giving this game a try.
