7×7 Thor: Slot Overview

Plenty of slots appear and disappear without leaving much of a trace. A smaller number reshape the market, grabbing the attention of players and other studios. Pragmatic Play’s Gates of Olympus is one of those titles—hugely successful and a clear spark for a wave of lookalikes and similarly designed games. Rival developer 4ThePlayer seemingly took note, first launching 7×7 Zeus (2024), a scatter-paying slot featuring multiplier symbols, and then largely giving that concept a new coat of paint with 7×7 Thor, another scatter pays title with multipliers and a mighty god taking centre stage.

That said, while 7×7 Zeus borrowed several Gates-style ideas, it also introduced its own twists, including a play area that expands. As before, the star of 7×7 Thor stands beside the reels, set against a sweeping outdoor backdrop. This time it’s mountains, a glowing borealis, and rolling storm clouds—a harsh, dramatic setting. The combination of an imposing deity and energetic scenery works just as well here as it did in the earlier game, and much like in Gates of Olympus, which these 4ThePlayer releases arguably trace their roots back to.

7×7 Thor’s grid can expand both across and down, though every base game spin begins in a 5×5 pattern. Under the snowy peaks sits a highly volatile math model, returning an RTP of 94% when staking 20 c to $/€80 per spin or when selecting any of the three bonus buys. There’s also a Power Bet option that increases the total bet by 25%, boosting the likelihood of activating Asgard Free Spins.

Wins are formed by landing 7 or more matching symbols anywhere on the grid. Winning symbols are removed, new ones drop in to fill the gaps, and the process continues until no further wins land. Low-paying symbols include 6 rune-cut stones, a horn filled with froth, crossed axes, a ship, a wolf, and a female character. Scatter combinations of 7-9 OAK pay 0.2 to 8 times the stake, rising to 1.5x-100x for 12 or more of a kind.

7×7 Thor: Slot Features

7×7 Thor carries over most of the same mechanics found in 7×7 Zeus, including grid-expanding Thunder symbols, Multiplier symbols, free spins with progressive grid growth and a progressive Bonus Multiplier, plus feature buys.

Thunder Reels

Hitting a Thunder symbol increases the size of the reels. Each Thunder symbol that lands adds a new row or column (or one of each) to the play area, expanding it from 5×5 up to a maximum size where 49 symbols may land.

Multiplier Symbol

Multiplier symbols can appear on any spin or during any symbol drop, starting with multis of x2 to x250. When a winning combination hits, every multiplier symbol on screen doubles in value (up to x250). If one or more Thunder symbols land and the grid expands, multiplier symbols also double in value. Once the action ends with no more wins, the payout is multiplied by the combined value of all multiplier symbols currently visible on the reels.

Asgard Free Spins

Landing 3, 4, or 5 scatters awards 12 free spins. During free spins, whenever the grid area increases, the expanded size stays in place until the feature finishes. The round uses a global Bonus Multiplier that begins at zero. Multiplier symbols that contribute to a win add their value to the Bonus Multiplier after the win is worked out. The Bonus Multiplier carries over between free spin and is added to the value of multiplier symbols on screen when a win occurs. Landing 3 or more scatters awards +6 free spins.

Feature Buy

7×7 Thor includes three feature buys rather than two. You can purchase Asgard Free Spins for 85x the bet, A Multiplier Spin that guarantees a win plus one or more Multiplier symbols for 125x the bet, or a Super Multiplier Spin for 200x, which guarantees a win and one or more Multiplier symbols with a minimum multiplier of x10.

7×7 Thor: Slot Verdict

Even if 7×7 Zeus didn’t reach Gates of Olympus levels of hype, it still delivered a capable scatter pays experience with multiplier symbols and extra layers. It felt familiar enough to tempt Gates fans, yet distinct enough to make the move worthwhile. Clearly it did enough right to earn a rework, because 7×7 Thor returns with essentially the same core approach, aiming for a top win of 10,149x the stake, while adding a couple of extra wagering options. One is the Power Bet, which is the more understated addition next to the Super Multiplier Spin buy. Neither the new ante bet nor the new buy is especially groundbreaking, but they do bring something extra to the 7×7 Zeus setup that some players may have wanted.

Put those two additions—and the change of gods—to one side, and 7×7 Thor is largely a close match to the earlier release. In general, a multiplier framework pairs perfectly with a scatter pays win system, and having multiplier symbols double after a win or after the grid expands creates a lively DoubleMax-style feel. With more symbols on the screen, you’d expect more opportunities for matches to land, so the expanding grid concept is a sensible touch too. In free spins, both the Bonus Multiplier and the expanded grid persist, making the feature a strong place to be—assuming multiplier symbols show up and do their job.

Overall, 7×7 Thor is another dependable scatter pays slot with some appealing add-ons. The RTP is on the low side versus much of the competition, and it doesn’t offer a huge amount beyond what 7×7 Zeus already had, but this play style is clearly popular, and 4ThePlayer has produced another respectable entry in the series.
