Power of Thor Megaways

The Megaways engine and reel structure

Power of Thor Megaways runs on six vertical reels with an additional horizontal sliding reel at the top. The Megaways engine varies the number of symbols shown on each reel with every spin, and the sliding top reel adds extra symbols that can apply across the main reels below. When all reels display their maximum symbol count, the total number of active ways reaches 117,649.

In practice, the active way count changes every spin. A spin where all reels show two symbols produces far fewer than 117,649 ways; a spin where all show seven or more produces the maximum. The variable way count is the core variance driver in the Megaways format: any individual spin has a different potential win structure depending on the reel layout it produces.

Cascade wins apply. When a winning combination forms, those symbols are removed and new ones fall from above, potentially creating a new combination without the player re-staking. Cascades continue until no new combination forms.

The unlimited progressive multiplier

The free-spins round is the primary return driver. Scatter symbols trigger it, and within the round an unlimited progressive multiplier accumulates. It starts at 1x and increases by 1x for each cascade win that occurs. The multiplier does not reset between individual free spins in the round; it only resets when a new free-spins round starts.

A free-spins round that produces cascade wins early generates a high multiplier for the later spins. A later spin with a large Megaways combination under a high multiplier is the scenario that produces the game’s significant wins. The multiplier’s unlimited ceiling is what creates potential beyond the typical fixed-multiplier free-spins design.

That potential is bounded by the 5,000x hard cap. Any combination of cascades and multiplier that would produce a win above 5,000x is paid at exactly 5,000x. This cap is a deliberate design choice, not a technical limit; Pragmatic Play has published 5,000x as the game’s maximum win figure.

Double wild reels in the base game

During base-game spins, random reels can become double wild reels. When this triggers, the selected reel fills entirely with wild symbols, substituting for all regular symbols in any combination that crosses that reel. A double wild reel on a spin with a high active way count creates simultaneous wins across many combinations at once and is the base-game event with the highest immediate value.

Norse design and symbol hierarchy

The game’s visual identity uses Norse mythology: Thor’s hammer Mjolnir, Asgard imagery, rune symbols, and a storm-lit colour palette. Thor himself is the highest-value symbol; the runestone symbols fill the mid-value tier; standard playing-card suits make up the low-value fillers.

High-value symbol combinations on maximum way-count spins or under the free-spins progressive multiplier are the scenarios that drive the game toward meaningful wins. Low-value symbol combinations, regardless of the multiplier level, produce modest returns.

Bankroll and the 5,000x cap in context

High volatility combined with a 5,000x cap creates a specific player experience: the game can produce significant wins in free spins, but a run of cascades that builds a very high multiplier will cut off at the cap regardless of how favourable the symbol distribution was. For players expecting uncapped outcomes from an unlimited multiplier, the cap is the most important piece of information about this title.
