7×7 Thor Slot

7×7 Thor Slot RTP, Details & Wager Limits

The 7×7 Thor base game kicks off on a 5×5 grid. Like many new online slots, it skips fixed paylines for a wins-pay-anywhere setup—land 7 or more matching symbols anywhere, and you’ve got a win. Then, those winning icons vanish while new ones drop in, and this keeps going until no more hits show up.

As for the betting range, it’s pretty typical for online slots, starting at 20p and going up to £80. There’s the autoplay mode you can enable if you’re playing in non-UK 7×7 Thor casinos. It allows you to set anywhere from 10 to 100 automatic spins with single win and loss limit options.

The 7×7 Thor RTP is on the lower side compared to the best online slots, at 94%. That’s the default option, but you may encounter the 90.5% version as well. Also, since it’s highly volatile, I wouldn’t recommend going in expecting frequent wins. Payouts can take a while. On the bright side, when they hit, they’re usually bigger.

For the 7×7 Thor max win, you’re looking at up to 10,149x your bet, which stacks up pretty well against the best payout slots. I haven’t landed anything close to that amount yet, not even in the 7×7 Thor demo. However, from what I’ve seen, the big wins lie in the free spins round. There, multipliers build with every drop.

7×7 Thor Theme—Northern Lights, Rugged Peaks, and a Frozen Saga Unfolding

4ThePlayer packed a lot into this Norse mythology-inspired slot. The reels sit inside a glowing gold frame with the background stretching into a frozen arctic landscape under a sky lit by the Northern Lights. Thor stands to the left, hammer in hand, ready to charge in at any moment.

I especially love how everything’s in motion. You’ve got the clouds drifting and the aurora dancing. What makes it even better is the soundscape tying everything together. This applies to both the background music and the sound effects, like the crackling buildup right before you land that third scatter in the base game.

7×7 Thor goes beyond the typical symbols you see in the most popular games across UK slot sites. The lower-paying ones are 6 rune-carved stones, while the premiums include a drinking horn overflowing with frothy ale, crossed axes, a Viking ship, a wolf, and what looks like a Valkyrie. There’s also a scatter, but no wilds.

Below is the full list of symbols and their payouts:

Symbol	Payouts/Info
Teal Rune	7 to 12+ = 0.2 to 1.5x stake
Green Rune	7 to 12+ = 0.3 to 3x stake
Blue Rune	7 to 12+ = 0.4 to 4x stake
Purple Rune	7 to 12+ = 0.6 to 5x stake
Orange Rune	7 to 12+ = 0.8 to 6x stake
Red Rune	7 to 12+ = 1 to 8x stake
Drinking Horn	7 to 12+ = 1.2 to 10x stake
Crossed Axes	7 to 12+ = 1.5 to 12x stake
Viking Ship	7 to 12+ = 2 to 20x stake
Wolf	7 to 12+ = 3 to 30x stake
Valkyrie	7 to 12+ = 8 to 100x stake
Bonus Scatter (Thor’s Hammer)	3 to 5+ = 2.5 to 150x stake; 3+ trigger free spins

7×7 Thor Mobile Slot

I expect nothing less than top quality when playing 4ThePlayer slots across mobile casinos, and 7×7 Thor came through just like I figured it would. I especially appreciate how well it’s optimised for smaller screens, fitting perfectly in both portrait and landscape. On that note, since the latter option gives you a better view of the background, I ended up using it more.

Still, the vertical view lacks nothing when it comes to the quality of the visuals or general user experience. Everything’s easy to reach with your thumb, and the reels stay perfectly centred—a feature you’ll find in lots of other free slots on our website.

7×7 Thor Bonus Features

You’ll find 5 bonus features built into the 7×7 Thor slot game.

Thunder Reels

The base game starts with a 5×5 grid, but each Thunder Scatter that lands adds a new row, column, or both. Also, multiple Thunder Scatters can appear on a single spin or symbol drop.

Ultimately, the grid can grow up to 49 symbols in various layouts, including 5×9, 6×7, 8×6, and more.

Multiplier Symbol

Multiplier symbols can land on any spin or symbol drop with values ranging from 2x to 250x. Every time a winning combination hits, all visible multipliers double in value. And if one or more Thunder Scatters land and expand the reels, any existing multipliers also double. Yet, no matter how many times it doubles, a single Multiplier Symbol can’t go higher than 250x.

Once all symbol drops finish and no more wins appear, the total multiplier value on the reels is applied to the final payout.

Asgard Free Spins

Landing 3 or more bonus scatters triggers the Asgard Free Spins feature, awarding 12 spins regardless of how many scatters land, along with a cash prize.

During free spins, you start with a 5×5 grid, but this can expand. And if the reels grow, they stay that way for the rest of the feature.

There’s a Bonus Multiplier involved, which starts at 0x and builds up throughout the free spins whenever Multiplier Symbols land and are part of a win. Note that each winning multiplier gets added to the total, which carries over between spins instead of resetting. However, keep in mind that you need at least one Multiplier Symbol to be involved for the Bonus Multiplier to apply. Also, landing 3+ Bonus Scatters rewards 6 extra spins.

Power Bet and Buy Feature (Not Available in UK Online Casinos)

Use the Power Bet option to increase your chances of triggering Asgard Free Spins while raising your total bet by 25%.

In the meantime, the Buy Feature option lets you instantly access one of these 3 extras:

• Asgard Free Spins: Instantly triggers the free spins bonus for 85x your bet.
• Multiplier Spin: Guarantees a win with at least one multiplier for 125x your bet.
• Super Multiplier Spin: Secures a win with a multiplier of at least 10x for 200x your bet.

7x7 Thor Slot

7×7 Thor ditches traditional paylines for scatter pays and quite literally builds up momentum with every spin with its expanding reels. If you’re after a slot that thrives on volatility and massive potential, this one surely knows how to bring the thunder.

Pros

• Expanding reels mechanic
• Stacking multipliers
• High max win (10,149x the stake)
• Smooth mobile optimisation

Cons

• Lower-than-average RTP
• No wild symbols
• Not the most original approach

The 7×7 Thor slot holds up well on its own. For starters, the reels expand with Thunder Scatters, which open up more ways to win. Every win also triggers a cascade that clears space for new symbols to drop in. On top of that, there are 3 main bonus features, so plenty is happening beyond the base game.

The question is, does it play things a little too safe for those who’ve seen similar setups before? I’d say yes. Having played 21 Thor Lightning Wayz and 7×7 Zeus, this one feels a bit too familiar, especially in how it looks. I would’ve loved to see something more creative from 4ThePlayer.

That said, 7×7 Thor still checks all the right boxes, particularly with its 10,149x max win, high-quality visuals, and mobile-friendly design. If you’re more into chasing big hits over slow grinds, definitely give the free demo a go.
