Power of Thor Megaways (Pragmatic Play) RTP review: 96.55% (configurable)
What 96.55% RTP means on Power of Thor Megaways
Power of Thor Megaways carries a published RTP of 96.55%, a theoretical house edge of roughly 3.45% over the long run. Because Pragmatic Play ships this game in multiple RTP builds, that edge only holds where a casino licenses the top version; a lower build quietly raises the edge against you, which is exactly why we flag configurable titles instead of quoting the headline unqualified. As always, RTP is a long-run average over millions of spins, not a per-session promise: the edge is real and permanent, and a high RTP never turns a slot into a reliable source of income.
Volatility, max win & features
Volatility is rated high (5/5). Expect long gaps between meaningful wins, with most of the return concentrated in the bonus — a friendly RTP does not make this a smooth, low-risk grind. The top prize is capped at 5,000x your stake, and the headline features are megaways, tumble, free spins (spell thor), progressive win multiplier (no reset in free spins), hammer feature, bonus buy.
What to know before you play Power of Thor Megaways
- Check the RTP build. Pragmatic Play licenses Power of Thor Megaways at 96.97% / 95.81% / 94.77% — open the in-game "i" screen and confirm you're on 96.55% before you commit a bankroll.
- Bankroll for variance. At high volatility the bonus carries the return — size your stake for long dry spells, not the 5,000x ceiling.
- Feature-buy (not in the UK). Buying the bonus shifts the effective RTP — the in-game info screen shows the buy-specific figure.
- High RTP is not profit. 96.55% still leaves a 3.45% long-run house edge; it lowers the cost of play, it never flips the odds in your favour.

Our verdict on Power of Thor Megaways
Skip if: your casino only offers a lower-RTP build of this game
Power of Thor Megaways is a high-volatility (5/5) Norse-themed Megaways slot on Pragmatic's 6-reel, up-to-117,649-ways cascading engine. Its defining feature is the free-spins round, triggered by spelling THOR with scatters, where a progressive multiplier climbs on every consecutive tumble and never resets — the source of the 5,000x cap and the reason swings are extreme, with most of the maths sitting in the bonus. The RTP is configurable, which is why sources cite different numbers: the info box shows a blended 96.55%, but the certified builds are 96.97% (bonus-buy), ~95.81% (common non-buy default) and 94.77% (stripped), so return depends on the deployed build, not stake. The 100x Bonus Buy lifts the headline to the 96.97% tier but is blocked in regulated markets like Great Britain. It suits experienced high-variance players who accept long dry stretches for a top-heavy free-spins payout, and is poorly suited to small bankrolls or frequent-win seekers.
