How Power of Thor Megaways works

Power of Thor Megaways puts Norse mythology on a Megaways grid. There are six main reels, and each spin gives every reel between 2 and 7 symbols, so the number of ways to win changes from spin to spin. With every reel full, you get the maximum of 117,649 ways. Wins pay for matching symbols on adjacent reels starting from the left.

A seventh, horizontal reel runs across the top of the four middle reels. It adds extra symbols to those reels and is where the game's main base game feature lives. Thor's hammer can land on that top reel, taking up two spaces. When it does, every symbol on the reels directly below the hammer turns wild. On a Megaways grid that can mean a lot of wilds at once, and it is the most likely way to get a decent base game hit.

Every win triggers a tumble. Winning symbols vanish, the rest fall into place and new symbols fill the empty spaces. Tumbles keep going until no new win forms. Viking characters pay the most, and the low end of the paytable is made of card ranks.

Power of Thor Megaways free spins and bonus features

The bonus is triggered by the scatter letters T, H, O and R. Spelling Thor's name with four or more scatters gives 10 free spins, and extra scatters on the trigger add more, with up to 30 spins possible from one trigger.

Before the round starts, you get a choice. You can take the spins as they are, or gamble them on a wheel for a chance at more. The gamble can also lose the whole bonus, so only take it if you are happy to walk away with nothing.

During free spins, a win multiplier starts at 1x and goes up by 1x with each tumble win. It does not reset between spins, so long tumble chains early in the round set up every spin that follows. More scatters during the round add extra spins. The bonus ends at once if your total win reaches the 5,000x cap.

Some casinos outside the UK offer a bonus buy for this game. If yours does, the price is shown next to the reels, and it is usually blocked when you play with a bonus.

Power of Thor Megaways RTP versions: what to check

Pragmatic Play lists the RTP at 96.55%, which is above the usual 96% mark. As with every game from the studio, casinos can choose a lower setting instead. The game looks and plays the same, so you can only see the difference in the rules.

Open the game, press the menu or "i" button and scroll to the return to player line. If it shows 96.55%, you are on the top setting. If it is lower, the features and cap stay the same but the house keeps more per spin. Our RTP and volatility guide explains why that matters over a long session.

Max win and volatility in practice

The 5,000x cap is modest next to newer Megaways games, but it is far from small. Sources rate the volatility high, and Pragmatic Play's own launch release called it a high volatility title. Most of the upside sits in the free spins, where the multiplier needs a few good tumble chains before wins get large.

That means long base game stretches with small payouts and the odd hammer hit. If you are clearing a bonus, the swings make a long wagering target harder to reach, so check the numbers with our wagering calculator before you choose a stake.

Playing Power of Thor Megaways with free spins or a bonus

If you plan to play this game with a casino bonus, read the terms before you start. Bonus buys and gamble features are commonly excluded during wagering, and most casinos set a maximum bet per spin until playthrough is done. Breaking a rule can cancel your winnings.

Our guide to wagering requirements covers how playthrough works, and you can compare current deals on the free spins page. For a casino with a big slot lobby, have a look at our Mostbet review.

Our verdict on Power of Thor Megaways

Power of Thor Megaways is a classic Megaways game with two good ideas: the hammer that turns whole reels wild and a free spins multiplier that keeps climbing. The 96.55% RTP is solid, and the gamble wheel adds a choice that most slots skip. The 5,000x cap is lower than many newer releases, which some players will see as a drawback. If you want a high volatility Megaways game with clear rules, it still holds up well. Check the RTP in the game info screen and decide on the gamble wheel before the bonus lands, not in the moment.
