Why Power of Thor Megaways still holds up in 2026
Three reasons:
- The unlimited progressive multiplier is unique — most Megaways titles have a cap (x10, x25). Here, it keeps climbing as long as cascades keep chaining
- 96.97% RTP on Bonus Buy — above Pragmatic's usual average (which often tops out at 96.5%)
- Double Wild Hammer — a signature feature that can turn a dead spin into a big win
Mechanics in detail
Base game (6 reels + Megaways top row)
6 main reels with variable height plus a top row with 4 positions add up to 117,649 ways to win. Symbols: Thor (top pay at 50x), Mjölnir, Loki, plus the classic A-10. Wild Hammer and the Asgard scatter trigger free spins.
Tumble Wins
Symbols forming a winning combination disappear and are replaced by the symbols above (a cascade). Multiple consecutive wins are possible on a single spin.
Free Spins (the heart of the game)
4+ Asgard scatters trigger 10 free spins (a Gamble option is available to boost this to 12, 15, 20, or 30 spins with proportional risk). During the bonus, every winning cascade adds +1x to the multiplier — with no official cap. Theoretically, a long chain of cascades can push the multiplier to dozens of x. That's what creates the potential for big runs.
Double Wild Hammer
A random feature during free spins: Thor strikes with Mjölnir and turns 2 reels into stacked wilds — an almost-guaranteed big hit on the following spin.
Bonus buy at 100x stake (96.97% RTP)
Available (except in the UK). The notable point: the Bonus Buy version's RTP is 96.97%, or 0.42% above the standard RTP (96.55%). That's rare for Pragmatic and makes the bonus buy particularly attractive on this slot.
RTP — 96.55% / 96.97% Bonus Buy
| Version | RTP | Recommendation |
|---|---|---|
| Standard | 96.55% | Top tier for modern releases |
| Bonus Buy | 96.97% | Above average — a strong pick |
| Alternative | 95.81% | Avoid |
| Degraded | 94.77% | Avoid entirely |
Note: the Bonus Buy version has an RTP higher than standard — this is the only Pragmatic Megaways title where that's the case. If you play Power of Thor regularly, the bonus buy is mathematically the better option over time.
