Power of Thor Megaways (Pragmatic Play) RTP review: 96.55% (configurable)
The blended headline problem
Power of Thor Megaways is the slot to study if you want to see how messy "RTP" can get. Pragmatic's basic-game info shows a blended 96.55% headline — but the actual certified builds are 96.97% with the Bonus Buy in use, 95.81% for the regular non-buy default, and 94.77% at the floor. Read that again: the ordinary spinner's build is 95.81%, while the buy route certifies over a point higher at 96.97%. Where buying is legal, this is one of the few Pragmatic games where the feature buy is unambiguously the mathematically privileged way to play; UK players, barred from buying, are locked into the weaker figure. The info screen shows what applies at your casino — read it with this ladder in mind.
Spelling THOR under a hammer
The game itself is a six-reel Megaways (to 117,649 ways) with tumbles, whose free spins trigger by collecting letters to spell THOR — a collection quirk that spaces bonuses differently from scatter games. Inside the feature, the win multiplier climbs with the action and does not reset between spins, the same coveted rule as Great Rhino Megaways; a Hammer feature strikes the board with modifiers to keep chains alive. The cap is 5,000x — a quarter of Rhino's, which is the main structural argument between the two unresetting-multiplier stablemates. Volatility: 5/5. Stakes 0.20–100.
How to play it rationally
The build asymmetry rewrites normal advice. Non-UK players intent on this game should price the buy against their session plans, because the 96.97% certification makes bought bonuses better long-run value than 95.81% spinning — an inversion of the usual buyer-beware. UK players and buy-averse spinners should simply note they're accepting sub-96% maths and weigh Rhino (95.59%+ builds, bigger cap) accordingly.
Mjölnir's measure
Worthy
- Unresetting free-spins multiplier with Hammer support
- Buy route certifies at a genuinely high 96.97%
- THOR-spelling trigger is a fresh bonus cadence
Unworthy
- Regular spin build is just 95.81% — below the shelf norm
- 5,000x cap trails its Rhino stablemate badly
- Blended 96.55% headline obscures the real ladder

Thor, weighed on the anvil
Skip if: you spin naturally — the 95.81% default is a quiet downgrade
Power of Thor Megaways is really two products sharing a hammer: a below-par 95.81% spinner and a 96.97% buy game, blurred together under a blended 96.55% headline that flatters neither. The unresetting multiplier and Hammer modifiers make its features worth having; the question is purely which door you enter through. Buyers (outside the UK) get one of Pragmatic's better-certified routes; spinners are better served by Great Rhino Megaways' higher builds and quadruple cap. Know which player you are before the first spin.
