Power of Thor Megaways slot

Is the Power of Thor Megaways slot right for you?

Power of Thor Megaways is a Norse-myth Megaways game from Pragmatic Play, the studio behind Gates of Olympus and Sweet Bonanza. It was released in 2021 and combines a six-reel Megaways grid with tumbling wins and a reel-filling hammer wild.

The key thing to understand is the pairing of high volatility with a 5,000x maximum win. Many high-volatility slots justify long dry spells with huge top prizes; this one caps out lower than several of its siblings. That makes it a game for players who enjoy the hammer and the free spins build-up, rather than chasing a giant ceiling.

With a default RTP of 96.55%, its cost per pound staked is in line with most of the Pragmatic Megaways range and better than many older games in our mobile slot reviews.

Power of Thor Megaways specifications and RTP

Because 96.55% is the default, an operator may have chosen a different setting. The game's own information screen is the place to confirm it; our page on how to find the RTP in a casino app shows the usual routes.

How the features work in Power of Thor Megaways

Tumbling wins

Every win removes the winning symbols, and replacements drop in from above. If the new symbols form another win, the tumble continues. One paid spin can therefore produce several wins in a row.

Thor's Hammer

Thor's Hammer is a wild that lands on the top reel, which sits above the main grid. When it lands, it turns the symbols in the reel directly below it into wilds. A full wild reel in the middle of a Megaways grid can link symbols across many ways at once.

Free spins with a rising multiplier

Four or more scatters trigger free spins, up to 30 of them. During the round a progressive multiplier rises by 1x with every tumble, so long tumble chains build a higher multiplier for later wins.

Gambling the spins before the round

Before the free spins start, you can choose to gamble the awarded spins for more. If the gamble fails, you lose the spins. Keeping them is the lower-variance option; gambling turns the bonus into an all-or-nothing moment.

The free spins gamble: what it does and does not change

Gamble options are not banned in the UK. The Gambling Commission's online slots stake limit guidance (opens in a new tab) even describes a player turning down a prize for a chance at a larger one within the same game cycle, as long as no extra stake is required.

There is no right answer that beats the house. If you are unsure, decide your rule before you start, for example always keeping the spins, so you are not making the call on impulse after a long wait.

Power of Thor Megaways cost per spin at 10p, 50p and £1

The house edge of 3.45% is what the game keeps, on average, from everything staked. The figures below use that edge and assume 600 spins an hour; the legal maximum pace is 1,440 spins an hour because each spin must take at least 2.5 seconds.

High volatility makes small budgets fragile. With £20 at £1 a spin you have just 20 spins, and with four or more scatters needed for the bonus, many sessions will end before it arrives. At 10p you buy far more time. The £5 row is the UK maximum for players aged 25 and over, shown to illustrate cost, not as a suggestion.

Playing Power of Thor Megaways on your phone

Pragmatic Play builds its slots in HTML5, so this game loads inside casino apps on iPhone, iPad and Android. It is part of the casino's lobby rather than a separate download from the App Store or Google Play.

The top reel where the hammer lands sits above the main grid, which makes the layout tall. The developer specifications do not confirm portrait support, so turn your phone if the top reel or scatter count is hard to read. Our guide to casino apps and battery life has tips if long sessions drain your phone.

1. Open a UK-licensed casino app with your age and identity already verified.
2. Search for Power of Thor Megaways in the game lobby.
3. Tap the information icon to read the RTP, the hammer rules and the free spins gamble.
4. Decide in advance whether you will keep or gamble any free spins you trigger.
5. Set a stake within your budget and the £5 cap (£2 if you are 18 to 24), then tap to spin each time.

UK slot rules and Power of Thor Megaways

In Great Britain, online slots follow the RTS 14 responsible product design standard (opens in a new tab). Since 31 October 2021 that has meant no autoplay, a 2.5-second minimum per spin, no turbo or slam-stop, and no celebrating wins that are equal to or less than your stake.

From 17 January 2025, net spend and time played must be visible in real time, and playing several games at once is not allowed. The £5 and £2 stake caps came in during 2025. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so the free spins must be triggered naturally. See our pages on the autoplay ban and UK game design rules.

Pragmatic Play Megaways slots like Power of Thor

Great Rhino Megaways has a much higher ceiling for similar volatility, while Madame Destiny Megaways and Buffalo King Megaways share the 5,000x cap. If the Norse theme is the draw, NetEnt's Vikings is another option. For apps with large Megaways libraries, see the best Megaways slot apps.

Limits worth setting before a high-volatility session

High-volatility games can swing fast in both directions. Setting limits beforehand keeps a bad run from turning into a bigger loss than you planned.

• Set a daily or weekly deposit limit in the app before you play.
• Never raise your stake to win back a lost free spins gamble.
• If you want a longer break, GAMSTOP (opens in a new tab) blocks all UK-licensed gambling sites and apps for 6 months, 1 year or 5 years.
• Free, confidential support is available from the National Gambling Helpline on 0808 8020 133, 24/7.
